Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a non-point source pollution reduction device,

The present invention relates to a non-point pollution source reduction apparatus, and more particularly, to a non-point pollution source reduction apparatus capable of efficiently removing and reducing a non-point pollution source generated from a bridge during rainfall, And a reduction device.

Recently, non-point pollution source refers to a pollutant source that flows out through an unspecified discharge route such as urban drainage and agricultural drainage. For example, when a non-point source pollution source such as fertilizer, farmland, Pollutants, pollution sources such as dust and garbage in urban areas.

Since these non-point pollution sources mainly flow out together with rain water during rainfall, the non-point pollution source reduction facility mainly focuses on collecting and processing the rainwater, and such non-point pollution source reduction facilities are largely classified into storage type, infiltration type, vegetation type, Type, and treatment type.

The storage-type abatement facility is a facility for sedimenting solid materials by storing stormwater in a certain space and inducing the natural purification of the pollutants. The permeation abatement facility is to induce the rainwater runoff to permeate into soil, gravel, sand, Or gravel, sand, or the like, which causes pollutants to be decomposed by microorganisms in the soil.

A vegetation-type abatement facility is a facility that plant trees in an excellent road to reduce soil erosion during rainfall, reduce sedimentation rate by planted trees when stormwater is introduced, induce sedimentation of solids, and purify pollutants. The facility-type abatement facility is a facility that removes pollutants contained in rainwater using a separate physical and chemical device. A treatment-type abatement facility is a facility that is equipped with a separate stormwater treatment facility, such as a sewage treatment facility, Means facilities that treat nonpoint pollutants.

Most of nonpoint source pollution reduction facilities applied to conventional bridges are infiltration type abatement facilities that mainly penetrate into soil without any other treatment facilities among the above nonpoint source pollution reduction facilities.

The conventional infiltration type abatement facilities include an excellent water collecting device provided on the upper plate of the bridge and a pipe connected to the excellent water collecting device. After the fine water flowing through the excellent water collecting device is moved through the pipe, It is a type to be discharged.

Such an intrusion type abatement facility is a very inefficient system, and the effect of reducing the substantial nonpoint source is very small.

On the other hand, in the case of the bridge on the river, the infiltration type abatement facilities mentioned above are mostly installed only on the land bridge, and most of the storms flowing into the excellent water collecting device provided on the bridge top plate are flowed directly to the river.

Therefore, the facility for reducing non-point pollution sources for bridges should be regarded as substantially not installed, and in most cases, the reduction effect is very small even when installed.

In recent years, some devices for reducing non-point pollutants in bridges have been developed and some have been imported and marketed. However, most of them are expensive equipments. Since the scale is large and a separate space is required for installation, There is a difficult problem.

A nonpoint source pollution reduction device installed on a bridge side to reduce pollution of water quality and pollution of the environment by efficiently removing and reducing the nonpoint pollution source from the rainwater and flowing the water into the river, ).

The main body 100 is of a receiving type and includes an inflow path 110 and a drain path 120 for inflow and discharge of a fluid such as contaminated water containing at least one surface pollution material ).

The fluid may be polluted or non-polluted, including non-point pollutants, generated in the bridge during rainfall.

The inflow path 110 and the drain path 120 may be connected to the main body 100 in the form of a pipe.

The purifier 200 is installed inside the main body 100 and efficiently removes and reduces the non-point pollutants from the fluid in a stepwise manner. As a result, .

The purifier 200 includes a first purifier 210 connected to the inside of the main body 100, a second purifier 220 and a third purifier 230.

Herein, the first purification tank 210 is configured to block and remove suspended matters and sediments of nonpoint pollutants from the fluid flowing through the inflow channel 110, and preferably the first purification tank 210 ) Receives the precipitate of the non-point pollutant settled from the fluid flowing through the inflow channel (110), blocks floating of the non-point pollutant from the fluid on the inner surface, and removes the float And a plate-like blocking member 211 which is horizontally joined at least one along the up and down directions.

At this time, one end of the blocking member 211 is biased downward about the inner surface of the first purification tank 210, and the upper surface and the lower direction of the blocking tank 211 are formed on the inner surface of the first purification tank 210, Accordingly, contaminants floating from the fluid introduced into the first purified water tank 210 can be more easily blocked.

Herein, the second purifying tank 210 serves to absorb and remove non-point pollutants from the fluid flowing from the first purifying tank 210, and is formed in a receiving form, and on the inner surface thereof, And at least one filter induction pipe 221 connected to the filter induction pipe 221 and connected to receive the fluid from the filter induction pipe 210, And at least one adsorption filter (222) for adsorbing and purifying the adsorbent.

3, when the fluid flows into the first purified water tank 120 through the inflow path 110, the non-point pollution source reduction apparatus of the present invention detects the presence of the solid precipitate in the non- While the suspended matters contained in the fluid are contacted with the bottom surface of the blocking member 211 while being prevented from flowing into the second purified water tank 220 side, Is first purified.

The fluid purified by the first purification tank 120 flows through the filter induction pipe 221 of the second purification tank 220 and is guided to the adsorption filter 220 side, In the process of passing through the adsorption filter 220, the adsorbent incorporated in the adsorption filter 220 adsorbs non-point pollutants such as contaminants and oil contained in the fluid, thereby purifying the fluid.

The fluid that has been subjected to the second purification treatment flows into the third purification tank 230 through the inlet hole 231 of the third purification tank 230 and the fluid injected by the water pressure through the inlet hole 231 Collides with the screen member 232 and falls downward to enter the filtering filter 240.

The fluid guided and introduced through the filtration net 242 of the filtration filter 240 passes through the filtration net 242 and the filtration media 243 and is subjected to third-order filtration of non-point contaminants contained in the fluid, The processed fluid flows downward through the filtration filter 240 and drained to the outside through a drainage path 120 connected to the third purification tank 230.

Accordingly, as the fluid is sequentially deposited, suspended, adsorbed, and filtered through the first, second, and third purification tanks 210, 220, and 230, Reduction and removal are excellent, and as a result, water pollution and environmental pollution can be reduced.
