Description

Distributing Vessel of Beginning Rainwater Concentration and storaging System Using the Same

The present invention controls the flow distribution tank so that the storage tank and the continuous treatment tank complementarily operate according to the concentration during rainfall, thereby improving the water treatment efficiency while preventing the flow load and the pollutant load in the whole system, and the inflow water of the medium concentration and the low concentration is separate. The present invention relates to a flow rate distribution tank that is economical and has no place limitation because it can reduce the land area by allowing continuous processing without storage of oil and a storage and continuous processing complex system using the same.

In general, in the combined sewage pipe, the total amount of sewage generated during the dry season is transferred to the sewage treatment plant through the conduit, but during rainfall, the flow rate exceeding the capacity of the conduit is overflowed. The combined sewage overflow water is known to be one of the main causes of polluting rivers when discharged into adjacent waters because of the discharge of surface pollutants and sediments in conduits.

Storage tanks and continuous treatment tanks (apparatus-type treatment facilities) have been proposed as technologies to treat inflows such as combined sewage pipe overflow water generated during rainfall, initial rainwater, and untreated sewage.

In the case of the continuous treatment tank, the treated water is discharged to the stream by treating such influent, and as shown in FIG. In particular, when a pollutant load is generated due to a blockage of the device, there is a problem of releasing the discharged water exceeding the effluent quality standard or doubling the probability of generating a flow load.

In addition, in the case of the storage tank to treat the inflow water so that the treated water flows into the sewage treatment plant, as shown in Figure 6 can be stored by treating the initial high concentration influent water, but in this case also the flow load occurs and the overflow water is intact It must be discharged, and in order to compensate for this, it must be large in size, which causes uneconomical and site-limited problems. That is, such a storage tank is used to treat high concentration of influent, and in the case of the existing storage tank, even if the high concentration inflow water enters the storage tank, it is diluted by the low concentration inflow water introduced into the storage tank, so there is a problem that the size of the storage tank must be increased. In storage tanks, there is a need to store influent by concentration.

Accordingly, Korean Patent Application Publication No. 10-2008-4647 provides an influent measurement unit provided in a conduit to measure the quantity and quality of influent water flowing into the conduit; A storage tank connected to the collection conduit, the inner space being divided into a high concentration storage tank accommodating a high concentration of inflow water from the intake water of the collection conduit by a partition wall, and a low concentration storage tank accommodating a low concentration inflow water from the inflow of the collection conduit; An opening / closing valve unit for switching the inflow water discharge direction of the collecting pipe into one of the high concentration storage tank and the low concentration storage tank; And a control unit for controlling the opening / closing valve unit according to the data measured by the inflow water measuring unit, to separate and store the inflow water of the collection conduit in the high concentration storage tank and the low concentration storage tank for each concentration. Suggesting.

In the above technology, there is a side to increase the treatment efficiency by storing the inflow water by concentration at rainfall. However, by having a separate storage tank of low concentration and treating it by a treatment facility, the required site according to the storage tank is increased, thereby limiting the construction cost and urban application. There is a problem.

Korean Patent Application Publication No. 10-2008-4647

The present invention has been made to solve the above problems, by reducing the flow load of the system by classifying and treating the influent by the concentration during rainfall, and at the same time can be discharged by continuously treating the medium and low concentration influent without storage. Therefore, to provide a flow distribution tank that does not need a separate storage facility for this, and a storage and continuous processing complex system using the same.

As a means for solving the above problems, the flow distribution tank according to the initial excellent concentration of the present invention, the body is formed a space therein; A guide wall partitioning the inside of the main body so that an inflow passage is formed at one side and a discharge passage is formed at the other side, and a communication path is formed so as to communicate between an end portion of the inflow passage and a start portion of the discharge passage; An inlet formed at the beginning of the inflow passage so as to introduce the inflow water; A low concentration outlet formed at an end of the inflow passage and openable; And a high concentration outlet formed at an end of the discharge passage and capable of opening and closing.

In addition, the induction wall is formed to be inclined gradient, it is reasonable that the width is narrowed from the beginning of the inflow passage to the end of the inflow passage.

In addition, it is reasonable that the height of the guide wall is less than or equal to the height of the low concentration exit.

In addition, it is reasonable that the inlet flow passage is composed of the needles formed between the guide wall and the main body.

It is reasonable that the sedimentary wear is inclined gradient is formed, the sediment discharge hole is formed in the induction wall portion that the sedimentary wear is in contact.

In addition, it is reasonable that at the beginning of the discharge passage, a rounded flow rate preventing prevention wall is formed at the corner of the main body.

In addition, it is reasonable that the bypass passage is formed at the top of the main body at the end of the inflow passage.

On the other hand, the combined flow and storage system using the flow distribution tank according to the concentration of the present invention, the flow distribution tank; A storage tank communicating with said high concentration outlet in said flow distribution tank; And a continuous treatment tank communicating with the low concentration outlet in the flow rate distribution tank.

In addition, the measuring unit for measuring the contaminant concentration in the inflow water into the flow distribution tank; It is reasonable that the controller is further configured to control the opening and closing of the high concentration exit and the low concentration exit in conjunction with the measuring unit.

Based on this configuration, when the pollutant concentration of the influent measured by the measurement unit is measured at a high concentration based on the reference concentration preset in the controller, the controller opens the high concentration outlet, closes the low concentration outlet, and measures the medium concentration. If the control unit is to open the high concentration exit and low concentration exit, it is preferable to close the high concentration exit and open the low concentration exit when measured at a low concentration.

As described above, the flow rate distribution tank according to the initial excellent concentration of the present invention and the storage and continuous treatment complex system using the same are used to mutually store and process the initial rainfall, combined sewage pipe overflow water, untreated sewage, etc. By complementary operation, there is an advantage that water treatment can be performed while preventing the flow load and the pollution load.

In addition, the flow distribution tank according to the concentration of the present invention and the storage and continuous treatment complex system using the same are economical because it is possible to reduce the land area by continuous treatment without separate storage of the medium and low concentration influent in the influent. This has the advantage of reducing place restrictions.

Hereinafter, the structure and operation of the present invention will be described in more detail with reference to the accompanying drawings. In describing the present invention, the term or word used in the present specification and claims is based on the principle that the inventor can appropriately define the concept of the term in order to best describe the invention of his or her own. It should be interpreted as meanings and concepts corresponding to the technical idea of

As shown in FIG. 1, the flow distribution tank 100 according to the initial excellent concentration of the present invention divides the main body 110 having a space formed therein and the inside of the main body 110 to have an inflow passage 130 at one side thereof. Induction wall to be formed and the discharge passage 140 is formed on the other side, and the communication passage 121 is formed to communicate between the end of the inflow passage 130 and the start of the discharge passage 140 ( 120, the inlet 150 is formed so that the inlet water is introduced at the beginning of the inflow passage 130, the low concentration outlet 160 formed at the end of the inflow passage 130 and openable and the discharge passage 140 It is formed at the end of the characterized in that it comprises a high concentration outlet 170 that can be opened and closed.

The main body 110 is not limited to its shape, but in FIG. 1 and the like, a rectangular plane is presented. Hereinafter, the main body 110 will be described based on the main body 110 having a rectangular planar shape.

First, the guide wall 120 is configured inside the main body 110 to partition the inflow passage 130 on one side and the discharge passage 140 on the other side. In addition, the communication path 121 is formed so as to communicate between the end of the inflow passage 130 and the start of the discharge passage 140, the induction wall 120 as shown in FIG. The communication path 121 is formed by starting at one side wall of the 110 and having a predetermined gap formed at the other end of the main body 110.

Here, the beginning of the inflow passage 130 refers to a point where the inflow water introduced through the inflow opening 150 starts to flow in the main body 110, and the beginning of the discharge passage 140 refers to the inflow. Inflow water flowing to the end of the flow path 130 refers to the point where the flow through the communication passage 121 starts to flow in the discharge passage 140.

As described above, the inflow water is formed at the beginning of the inflow passage 130, the end of the inflow passage 130, and the communication passage 121. Flow is formed at the beginning of the discharge passage 140 and the end of the discharge passage 140.

In addition, the induction wall 120 is formed to be inclined gradient, the width of the inlet flow path 130 in the inlet flow path 130 is formed so that the width is narrowed to the end of the inflow path 130, the inflow flow path 130 This is to increase the flow rate at the end of the inflow passage 130 so that the width of the) narrows. The reason for constructing the induction wall 120 is to prevent foreign substances mixed in the inflow water in the inflow passage 130 due to the flow rate of the inflow water. That is, the foreign matter mixed in the inflow water is introduced into the storage tank 200 through the high concentration outlet 170 as described below, and the foreign matter mixed in the inflow water into the continuous treatment tank 300 through the low concentration outlet 160. This is to prevent the discharge of contaminated loads such as occlusion of the discharged water that does not meet the discharged water quality standards or blockage in the continuous treatment tank 300.

In addition, the height h1 of the induction wall 120 is less than or equal to the height of the low concentration outlet 160 as shown in Figure 3 continuous processing tank 300 connected through the low concentration outlet (160) To prevent overload. That is, as shown in FIG. 2, inflow water at least higher than the height of the low concentration outlet 160 continuously forms the water flow ③ to overflow the guide wall 120 so as to immediately flow to the discharge passage 140. It is to prevent the load of the processing tank 300.

In addition, the inflow passage 130 is preferably configured such that the needle wall 131 formed between the guide wall 120 and the main body 110. The reason for configuring the immersion wear 131 is that when the flow rate of the inflow water in the inflow passage 130 is relatively small, foreign matters are deposited from the inflow water, thereby obstructing the flow of the inflow water or the continuous treatment tank 300 through the low concentration outlet 160. In order to prevent the foreign matter from flowing into the influent by controlling the deposition of foreign matters by the icing ware 131 to generate a load.

To this end, the icing ware 131 is a gradient gradient is formed so that the foreign matter deposited is concentrated in the direction of the guiding wall 120 from the icing ware 131, the guiding wall contacting the icing ware (131) ( The portion 120 is configured to allow the sediment discharge hole 122 to be discharged (④) to the discharge passage 140 so that the sediment eventually flows to the storage tank 200. That is to discharge the high concentration of influent water through the high concentration outlet 170 to be treated in the storage tank (200). The inclined gradient of the sergeant wear 131 means that the angle θ formed by the main body 110 and the immersion wear 131 forms an obtuse angle as shown in FIG. 2.

In addition, the inlet opening 150 is formed at the beginning of the inflow passage 130 so that the inflow water is introduced. As shown in FIG. 1, the inlet opening 150 is formed at one side wall of the main body 110.

In addition, the low concentration outlet 160 is formed at the end of the inflow passage 130 and is configured to be open and close, as shown in Figure 2 the water flow (②) in communication with the low concentration outlet 160 is mainly heavy As mentioned above, the flow rate is increased at the end of the inflow passage 130 by the inclined gradient of the induction wall 120, so that the foreign substances in the inflow water at the low concentration outlet 160 portion. It is to be introduced to the low concentration outlet 160 directly without deposition or to be guided to the discharge passage 140 through the communication passage 121. That is, the low concentration outlet 160 is to prevent the contamination load of the continuous treatment tank 300 by preventing the foreign matter deposited as structurally possible.

Here, the low concentration outlet 160 may be opened and closed to close the low concentration outlet 160 when the influent water flows at the initial stage during rainfall so that the high concentration inlet water is led to the high concentration outlet 170. The opening and closing of the low concentration outlet 160 may be performed manually, but may be performed automatically or manually by the control of the controller 700 to be described below.

In addition, the high concentration outlet 170 is formed at the end of the discharge passage 140, as shown in Figure 1, such as is formed in the main body 110 at the end of the discharge passage 140, mainly rainfall When the initial high concentration of influent water is introduced to the discharge tank 200 to be discharged. The influent flow (①) to the high concentration outlet 170 shown in Figure 2 will be a high concentration influent and medium concentration influent. Here, the opening and closing of the high concentration outlet 160 may be performed manually, but may be performed automatically or manually by the control of the control unit 700 to be described below.

In addition, the present invention as another configuration for preventing the flow rate of the inflow water in the main body 110 is a flow rate preventing wall rounded at the corner of the main body 110 at the beginning of the discharge passage 140 An example in which 111 is configured is shown. That is, the inflow water induced in the direction of the discharge passage 140 through the communication passage 121 forms a vortex at the corner portion of the main body 110 so that foreign matters are deposited or the discharge passage 140 through the communication passage 121. This is to prevent the flow of the inflow of the incoming water to eventually prevent the flow of ② ② of FIG.

Meanwhile, the flow rate distribution tank 100 of the present invention allows the bypass flow path 112 to be configured to prevent the load of the storage tank 200 and the continuous processing tank 300, the storage tank 200 and the continuous When the inflow of water exceeding the treatment capacity of the treatment tank 300 is discharged to the outside through the bypass passage 112. The bypass flow path 112 is not shown in the drawings, but may discharge the inflow water exceeding the processing capacity by a pump to the outside, and as shown in FIG. 1, the main body at the end of the inflow flow path 130 may be discharged. It can be formed on the top of one side wall of the 110 to allow the inflow water of a certain level or more to be discharged to the outside by the monthly overflow.

Meanwhile, in the present invention, as shown in FIG. 4, a storage and continuous treatment complex system (hereinafter, referred to as a “system of the present invention”) using a flow distribution tank according to an initial excellent concentration is also presented.

The system of the present invention comprises a flow rate distribution tank 100 according to the concentration; A storage tank 200 in communication with the high concentration outlet 170 in the flow rate distribution tank 100; And a continuous processing tank 300 in communication with the low concentration outlet 160 in the flow rate distribution tank 100.

In the case of the inflow water of the high concentration and the medium concentration in the inflow water introduced into the flow distribution tank 100 to open the high concentration outlet 170 based on the operation of the above-mentioned flow distribution tank 100 to enter the storage tank 200 will be. The inflow water of the high concentration and the medium concentration introduced into the storage tank 200 is to be discharged to the sewage treatment plant 400 while a certain flow rate is stored. Various techniques have been proposed, and description thereof will be omitted.

In addition, in the case of the inlet water flowing into the flow distribution tank 100 in the case of medium and low concentration inlet water, such as rainwater after the initial stage, the low concentration outlet 160 is opened based on the operation of the above-described flow distribution tank 100, and the continuous treatment tank. It is to be introduced to (300). The continuous treatment tank 300 is to be immediately discharged by performing a filtration by a known technique such as a filter, a screen, the continuous treatment when the inflow water flowing through the flow distribution tank 100 is introduced at a high concentration In order to prevent the discharge of the discharged water exceeding the discharged water quality standard due to blockage or the like in the tank 300, or to prevent the case where the discharged water flows into the medium concentration but the inflow flow rate is excessive to exceed the processing capacity of the continuous treatment tank 300. The structure of the guide wall 120 of the above-mentioned flow distribution tank 100, the opening and closing of the low concentration outlet 160 is presented.

Thus, the system of the present invention has a basic configuration of the flow distribution tank 100, the storage tank 200 and the continuous processing tank 300, and the other configuration is selectively configured as shown in Figure 1 to operate. .

In detail, the inflow port 150 of the flow distribution tank 100 is configured such that a contaminant treatment tank 500 is connected by a line 1 (L1) so that the specific gravity and the size in the previous stage of the flow distribution tank 100 are large. The foreign matter may be primarily filtered to allow the influent to flow into the flow distribution tank 100. The influent may be initial stormwater, combined sewer overflows, and sewage treatment plants.

In addition, the line 1 (L1) bar may be configured to measure the contaminant concentration in the inflow water to the flow distribution tank 100, the measurement unit 600, the measurement unit 600 is With the configuration for measuring the concentration, the concentration of contaminants may be turbidity, SS and the like. Although the measuring unit 600 shows an example configured in the line 1 (L1) in FIG. 1, the measuring unit 600 is not limited thereto and may be configured inside the flow rate distribution tank 100.

In addition, the control unit 700 is configured to control the respective components of the flow rate distribution tank 100, and the control unit 700 is interlocked with the measurement unit 600 based on a preset standard. 600 to control the opening and closing of the low concentration outlet 160 and the high concentration outlet 170 according to the concentration of the pollutant.

The flow rate distribution tank 100 is configured to communicate with the storage tank 200 by the line 2 (L2), mainly through the line 2 (L2) is a high concentration of influent flows, the medium influent also flows do.

In addition, the flow rate distribution tank 100 is configured to communicate with the continuous processing tank 300 by the line 3 (L3), through the inlet water of medium and low concentrations through the line 3 (L3).

In addition, the flow rate distribution tank 100, the line 4 (L4) is connected to the bypass flow path 112 of the flow rate distribution tank 100, line 4 (L4) is the flow rate of the flow rate distribution tank 100 Corresponds to the configuration to discharge to the outside for a flow rate exceeding.

The storage tank 200 flows the water stored in the capacity margin time to the sewage treatment plant 400 after the rainfall is finished while the inflow of high concentration or medium concentration flows into the storage tank 200 through the line 2 (L2). L5) is configured. By doing so it is to prevent the flow load that may occur in the sewage treatment plant 400 during rainfall.

Line 6 (L6) for introducing the medium or low concentration of inflow water from the flow distribution tank 100 through the line 3 (L3) to the continuous treatment tank 300 to discharge the treated water to the river or the like by filtration. Is connected. In this way, the continuous treatment tank 300 is to continuously inflow and treatment of the medium concentration or low concentration influent water to meet the discharge water quality standards to the end of the rain, can be treated without a facility for storing a separate medium concentration and low concentration influent water. Therefore, economical processing becomes possible.

In addition, bar 7 (L7) is connected to the storage tank 200 in the continuous treatment tank 300, line 7 (L7) is the treatment tank purified by the continuous treatment tank 300, the storage tank ( 200) to act as wash water.

An operation example of the system of the present invention will be described below.

First, in the event of rainfall, the influent is introduced into the flow distribution tank 100 by first filtering the foreign matter having large specific gravity and size from the contaminant treatment tank 500. In this process, the measurement unit 600 measures the pollution concentration of the influent water so as to interlock with the control unit 700, and the control unit 700 has a high concentration such as an initial excellent rain, which makes it impossible to process the continuous treatment tank 300. The low concentration outlet 160 is closed and the high concentration outlet 170 is opened in order to introduce the inflow water into the storage tank 200. This high concentration inflow water is introduced into the storage tank 200 by line 2 (L2), while the storage water is stored in the sewage treatment plant 400 through the line 5 (L5) while storing for a predetermined time (after rainfall type). To make it flow. That is to ease the flow load of the sewage treatment plant 400 during rainfall.

Next, when the contamination concentration measurement value of the measuring unit 600 becomes a medium concentration in the process of introducing the inflow water through the line 1 (L1) from the contaminant treatment tank 500 to the flow distribution tank 100, the continuous The control unit 700 opens the low concentration outlet 160 to treat the inflow of medium concentration into the treatment tank 300 to be treated. However, when the inflow water of the medium concentration is introduced, the flow rate is often the heavy flow rate, so that the controller 700 causes the flow rate to exceed the flow rate of the continuous processing tank 300 to flow into the storage tank 200. In this case, too, the high concentration exit 170 is opened. In the case of the medium concentration and the heavy flow rate inflow water, the flow load of the entire system by performing the treatment by the continuous treatment tank 300 and the storage treatment by the storage tank 200 at the same time based on the structure of the flow distribution tank 100. And to prevent the pollution load of the continuous processing tank (300).

Next, when the measured value of the measuring unit 600 becomes low in the process of introducing the inflow water from the contaminant treatment tank 500 to the flow distribution tank 100 through line 1 (L1) or the storage tank 200. When the water level becomes high, the control unit 700 is to close the high concentration outlet 170 to operate only the continuous processing tank 300, and to open the low concentration outlet 160. In this case, since the inflow water is low in concentration, the inflow water can be discharged by sufficiently treating the inflow water to satisfy the discharge water quality standard with only the continuous treatment tank 300, so that the control unit 700 operates only the continuous treatment tank 300. As described above, the continuous treatment tank 300 is capable of increasing the treatment capacity while reducing the load of the storage tank 200 without a separate facility by continuously discharging the influent water of the medium concentration and the low concentration.

That is, the present invention is to process while keeping the low flow rate and the high concentration of influent water in the storage tank 200, while the inlet water of the medium concentration and heavy oil flow in the continuous treatment tank (300) first to process the first In order to complement the processing capacity of 300, the storage tank 200 is operated at the same time, and the low concentration inflow water is treated by the continuous processing tank 300 only, the storage tank 200 and the continuous processing tank 300 mutually Complementary operation is to control the flow distribution tank 100 to prevent the flow load and contamination load.

Those skilled in the art will appreciate that various changes and modifications can be made without departing from the spirit of the present invention. Therefore, the technical scope of the present invention should not be limited to the contents described in the detailed description of the specification, but should be defined by the claims.
