Description

Movable Zero Discharge and Sewage Treatment System {MOVABLE ZERO DISCHARGE SYSTEM}

The present invention is to remove the organic rich substances and the causes of eutrophication (nitrogen and phosphorus, color and odor) contained in the sewage to purify the manure and sewage of the outdoor public toilet to the initial washing water level, and the treated water to the toilet The present invention relates to a mobile non-discharge manure and advanced sewage treatment device capable of protecting the water resources and preventing environmental pollution since the treated water is not discharged to the outside by recycling with water.

In general, the sewage discharged from outdoor toilets or domestic sewage not only contains a large amount of nitrogen (N) and phosphorus (P), which causes eutrophication, but also generates a bad smell. Nitrogen and phosphorus contained in sewage act as nutrients for the synthesis of proteins and nucleic acids for the activity and proliferation of microorganisms, and the surplus is removed or discharged to become a major cause of water pollution such as eutrophication.

Recently, biological treatment processes or chemical treatment devices and techniques have been developed to remove nitrogen, phosphorus, and odors contained in sewage, but most toilets or sewage treatment facilities apply chemical treatment processes due to inconvenient maintenance and burden of environmental impact. It is difficult to do so.

As an example, there is a natural fermentation type mobile or fixed toilet or a potent toilet equipped with a bubble generator as a means to reduce the odor inside the toilet, but the odor is severe because manure is accumulated and stored in a storage tank. It is unsanitary due to the occurrence of pests, and the inconvenience of having to collect manure and sewage on a regular basis and as a secondary environmental pollution source in the collected manure and sewage disposal are virtually impossible to operate. Therefore, publicly installed parks, walkways, riverside paths, and hiking trails have had many difficulties in efficient maintenance.

In order to solve the problems caused by the maintenance of the public toilets as described above, Republic of Korea Utility Model No. 321856 "Anti-purifying purifier using a toilet" has been disclosed, which will be described with reference to Figure 1 as follows. same.

A storage tank is connected to the toilet bowl 80, and a connection pipe 83 in which the cutter pump 82 is installed is coupled to the storage tank, and an aeration tank 84 is connected to the front end of the connection pipe 83.

The aeration tank 84 is provided in the tank 87 in which the exhaust port 86 was provided, and is connected to the storage tank by the connecting pipe 83 in the tank 87.

As an action on the vanishing type purification device configured as described above, when the sewage discharged from the toilet bowl 80 is introduced into the storage tank, the sewage from the storage tank again moves along the connection pipe 83 to be crushed by the cutter pump 82 While being conveyed to the aeration tank 84.

The sewage is then removed organic matter by aerobic microorganisms in the aeration tank 84, and at the same time the colorless odorless gas generated in the sewage is discharged into the atmosphere through the exhaust port (86).

The purified sewage is returned to the storage tank through the connecting pipe 83 and then circulated again through the same process as described above through the connecting pipe 83.

The conventional decay sewage treatment device as described above is purified only by aeration, so the purification ability is reduced due to the removal of nitrogen (N), phosphorus (P) and color and odor, and the treated water cannot be recycled in the toilet bowl separately. There are inconveniences that must be collected, and the collected wastewater is a secondary environmental pollutant, which is not only environmentally friendly but also very disadvantageous in terms of maintenance due to the additional cost of treatment.

An object of the present invention is to remove the manure and sewage in order to remove the organic rich substances contained in the manure and sewage discharged from the outdoor toilet and nitrogen (N) and phosphorus (P) and the color and odor to a recyclable level. 1 The aerobic reaction tank, the second aerobic reaction tank, the first advanced treatment tank, the second advanced treatment tank, the flow rate adjusting tank, the wood chip microbial reaction tank, and the decolorizing filtration tank are sequentially passed through and purified, and the purified treated water is not discharged to the outside. The present invention provides an environmentally friendly mobile non-discharge manure and advanced sewage treatment system that can not only protect water resources but also significantly improve maintenance by recycling the toilet water.

Another object of the present invention is not only a newly installed toilet, but also a conventional toilet in use, or the discharged water quality is exceeded to allow for a variety of sewage treatment facilities that can not be practically used to greatly improve the purification capacity as well as the existing It is to provide a mobile non-discharge manure and advanced sewage treatment device that can be used as it is and can be moved to another place if necessary.

In addition, the installation method can be fixedly installed in a specific place, for example, underground, above ground, on the roof of a building, and can be moved by installing the above components in the container 200.

The operation of the mobile non-discharge manure and advanced sewage treatment apparatus according to the present invention configured as described above will be described with reference to FIGS.

According to the operation command of the circuit control device 60 connected from the cutter pump 4 in which manure sewage or living sewage is installed in the outdoor public toilet or sewage purification system, the first screen through the transfer pipe 5. When transported into the first chamber 7a of the aerobic reaction tank 7, the sewage flowing into the first chamber 7a is stacked lattice stones 10 and oysters of the second chamber 7b along the transfer port 49. It is moved between the shell (11).

In the above process, the action of the components contained in the ganguerite (10) and oyster shell (11) and the decomposition of organic matter contained in the sewage by the action of the microorganisms that grow and act attached to the gantherite (10) and oyster shell (11) Nitrogen and phosphorus in the manure and sewage are also removed.

When the cutter pump 4 operates as described above, when the manure and sewage level of the storage tank 2a of the external toilet 100 or the sewage purification apparatus is lowered to a certain level, the water level sensor 3 detects this and the cutter pump 4 ), And when the sewage reaches a certain level again, the cutter pump 4 is operated to collect the manure and sewage pulverized through the transfer pipe 5 in the first aerobic reaction tank 7 and the first chamber 7a. Transfer to).

In the first exhalation reactor (7), the air pump (14) connected to the diffuser (9) installed in the second chamber (7b) is periodically operated by a command transmitted from the circuit control device (60) to diffuse air. The air is supplied through (9). At this time, when air is supplied through the diffuser (9), the first chamber (7) and the second chamber (7b) become aerobic, and when the air supply is interrupted, it becomes anoxic. At this time, the first chamber 7a and the first chamber 7a are partitioned into a second chamber 7b and a partition screen 8 and are operated in an almost anoxic state.

In the aerobic state as described above, ammonia nitrogen (NH-N) contained in the sewage is converted into nitrite nitrogen (NO-N), and nitrite nitrogen (NO-N) is again converted to nitrate nitrogen (NO-N). The nitrification reaction proceeds to conversion.

As described above, when nitrification proceeds, nitrifying bacteria nitrosomonas or nitrobacter are involved.

The nitrification process in the aerobic state is as follows.

(Nitrosomonas)

^{_{(1) NH 4 + + 3/2}} 0 2 ---------------> NO 2 - + H 2 O + 2H +

(Nitrobacter)

^{_{(2) NO 2 - + 1/2}} O 2 - ---------------> NO 3 -

In addition, when the aerobic state as described above, the microorganisms acidize the substrate stored in the cell to obtain energy for the biological reaction, and by using the re-absorbed phosphate phosphorus is stored in the form of polyphosphoric acid in the cell.

Unlike the above, when the air supply through the diffuser 9 is stopped, the inside of the first aerobic reactor is anoxic, whereby the denitrification microorganism proceeds with denitrification to release nitrogen (N).

The denitrification process is as follows.

_{^{NO 3 - ---> NO 2 -}} ---> NO ---> N 2 O ---> N 2

In addition, when the first chamber 7a and the second chamber 7b of the first aerobic reactor 7 are anaerobic, the microorganism hydrolyzes the polyphosphoric acid in the cell to release the phosphorous acid.

Phosphorus released as described above is excessively ingested by the microorganisms in the aerobic process, and these microorganisms are subsequently removed to achieve a biological dephosphorization reaction, and at the same time, the phosphorus contained in the sewage is first and second advanced treatment tank (53). ), (52) denitrification, dephosphorized media are adsorbed or decomposed.

In addition, aerobic microorganisms are parasitic on the surfaces of the oyster shell 11 and the wood chip media installed in the first and second aerobic reaction tanks 7 and 54, and anaerobic microorganisms of the oyster shell 11 and the wood chip media Parasitic on the inside, aerobic microorganisms store phosphorus in the cell while promoting nitrification, and anaerobic microorganisms denitrify NO ₃ ⁻ to release N ₂ and remove organic matter.

Subsequently, the sewage from which denitrification, dephosphorization, and organic matters are removed in the second aerobic reaction tank 54 flows toward the first advanced treatment tank 53 along the filtration device 17 and the discharge pipe 18.

The sewage introduced into the second aerobic reactor 54 is periodically driven by the air pump 16 by the circuit control device 60, and the atmosphere of the reactor is aerobic due to the air aeration of the diffuser 15 installed below the reactor. The environment is periodically formed and organic substances are adsorbed on the surface of wood chips and inorganic media, or decomposed and removed by aerobic microorganisms parasitic on the surface and anaerobic microorganisms parasitic inside the wood chip.

The sewage treated in the second aerobic reaction tank 54 passes through the filtration device 17 and is discharged toward the first advanced treatment tank 53. The operation occurring in this process and the configuration of the filtration device 17 will be described below. same.

In addition to physical filtration by wood chips installed in the filtration device 17, organic matters are decomposed and removed by aerobic and anaerobic microorganisms parasitic on wood chips, and organic matters are also simultaneously physiologically filtered by mineral media of elvan and activated carbon. Removed.

The denitrification and dephosphorization cube media 23 adsorb and decompose and remove nitrogen, phosphorus and organic substances contained in sewage.

The sewage treated by the above-described action in the first advanced treatment tank 53 passes through the filtration device 20 and flows along the discharge pipe 24 to the second advanced treatment tank 52.

In the second advanced treatment tank 52, the sewage is treated by the same method and operation as in the first advanced treatment tank 53, and the organic matter remaining in the sewage and the components such as nitrogen, phosphorus, and chromaticity are secondarily treated.

The sewage purified by passing through the filtration device 29 of the second advanced treatment tank 52 is introduced into the flow rate adjustment tank 51 through the discharge pipe 30.

The flow rate adjusting tank 51 detects the water level of the treated water introduced along the discharge pipe 30 in the second advanced processing tank 52, and then transfers the sensing signal to the circuit controller 60. By the circuit control device 60 to supply or cut off the power of the transfer pump (33). If the water level is detected above the reference value by driving the transfer pump 33 and the watering pump (34a) to return the sewage to the first aerobic reaction tank (7) through the conveying pipe 31 and at the same time Woodchip microbial reaction tank (55) To the) side.

If the amount of sewage flows into the flow rate adjustment tank 51 more than the quantity of water transferred by the transfer pump 33 and the water spray pump 34a, or when the pump is not driven due to a pump failure or power failure, It is discharged to the outside through the over-water discharge pipe 32 installed on the flow rate adjustment tank 51 to adjust the overall flow rate.

Of course, when the water level of the flow rate adjustment tank 51 is lowered below a certain level, the circuit control device 60 receives the signal sensed by the water level sensor 58 is supplied to the feed pump 33 and the watering pump 34a. Shut off power to stop both pumps.

In the wood chip microbial reaction tank 55, as described above, the filthy water transported by the transfer pump 34a, the transfer pipe 74, and the sprinkling nozzle 34 in the flow rate adjustment tank 51 is the wood chip microbial reaction tank 55. As described above, the intake process of phosphorus (P) is sprinkled on the surface of the wood chip 38 and is absorbed by the aerobic microorganism parasitic on the surface. It proceeds and substantially denitrifies by anaerobic microorganisms adsorbed inside the wood chip 38 to release nitrogen, and at the same time, residual organic matter is removed by the microorganisms.

As described above, the introduced manure and sewage are sequentially passed through the first aerobic reaction tank 7 and the second aerobic reaction tank 54, and the organic suspended matter, nitrogen (N), and phosphorus (P) are firstly treated. The organic matter, nitrogen, phosphorus, some chromaticity, etc. are secondarily removed while passing through the advanced processing tank 53 and the second advanced processing tank 52, and then sprayed onto the wood chip microbial reaction tank 55 for treatment. Residual organics, nitrogen, phosphorus and chromaticity are removed while the water passes through the layer of wood chips 38.

In the lower part of the wood chip microbial reactor 55, the air pump 36 supplies air by the control of the circuit control device 60, and the air is periodically supplied by the diffuser 37 to the wood chip 38 layer. Promote the activity and reproduction of parasitic microorganisms.

As described above, the treated water having almost completely removed organic matter, nitrogen, phosphorus, and chromaticity flows toward the decolorization filtration tank 41 along the discharge pipe 50 installed under the wood chip microbial reaction tank 55.

In the decolorization filtration tank 41, the treated water introduced from the wood chip microbial reaction tank 55 through the discharge pipe 50 flows from the first chamber 41a to the fifth chamber 41e, and is connected to each other through a sewage connection pipe. have. The connecting pipes are installed at the upper and lower portions of each chamber so that the treated water flows naturally from the bottom to the top and from the top to the bottom.

Therefore, while the treated water passes through the activated carbon 42 filled in the second to fourth chambers, the remaining organic matter remaining in the treated water is removed and at the same time, the turbid color remaining is cleared.

Therefore, when the level of the treated water flowing into the fifth chamber 41e rises by a predetermined value or more, the circuit controller 60 receives the signal sensed by the level sensor 59 and supplies power to the transfer pump 43. Thereby driving the pump. When the transfer pump 43 is driven, the treated water contained in the fifth chamber 41e of the decolorizing filtration tank 41 is transferred to the treated water storage tank 45 along the transfer pipe 44.

On the contrary, when the water level of the fifth chamber 41e falls below a predetermined value, the circuit controller 60 receives the sensing signal of the water level sensor 59 to cut off the power supplied to the transfer pump 43 to drive. Stop it.

On the other hand, the rainwater conveying pipe 71 is connected to the first chamber (41a) is installed, a portion of the treated water may evaporate in the process of operating the sewage treatment device (6). In this case, if the amount of evaporation is greater than the inflow of sewage, the water level is lowered. Thus, in preparation for such a situation, rainwater falling to the bathroom roof is collected through the rainwater conveying pipe 71 as shown in FIG. 2 to obtain rainwater. Use as supplementary water. With the inflow of rainwater, it is possible to eliminate the accumulated load of stored water, thereby improving water quality.

If the rainwater is excessively introduced into the decolorizing filtration tank 41, the transfer pump 43 relatively transfers a large amount of the treated water to the treated water storage tank 45. At this time, when a large amount of treated water flows into the treated water storage tank 45, the treated water is discharged to the outside through the over water discharge pipe 48 installed on the upper portion of the treated water storage tank 45.

The water quality of the treated water stored in the storage tank by the treatment process as described above has almost the same water quality as that of the washing water used in the toilet, and the treated water has a water pressure sensor when the flushing toilet 1 or the recycling tap water device 73 is used. (Not shown in the figure) operates the feed water pump 46 to supply the treated water to the flush toilet 1 tank and the recycling tap water 73.

Of course, the sewage generated by the use of the flush toilet (1) water tank and the recycling tap water device 73 is introduced into the storage tank (2a) again through the sewage discharge pipe is processed while circulating the configuration of the present invention as described above.

As described above, the purified wastewater is not discharged to the outside, and the above-mentioned process is repeated internally to remove the organic suspended solids contained in the manure and the wastewater, nitrogen and phosphorus as eutrophication substances, and color and odor. The water quality of the treated water can be treated at the same level as the quality of the first used washing water, which can greatly improve the purification efficiency.The purified water can be reused as toilet water or tap water, and the treated water is discharged to the outside. Water pollution can be prevented.

In addition, the entire sewage treatment apparatus 6 is manufactured by means of container type mobile installations without being fixed to one basement or one ground, and installed as well as newly installed facilities. If the present invention is simply connected to an unsanitary and bad smell toilet, such as a possum, or a sewage treatment apparatus that is virtually inoperable because the discharged water exceeds the allowable value, the existing facility can be operated as it is and is very economical.

In addition, if the use of the outdoor toilet or sewage treatment device no longer used during use, and the present invention is moved to another place, the pump 4 and the transfer pipe 5 connected to the toilet or the sewage treatment device as described above are simply When separated, the present invention can be moved to another place and used as it is, which is very economical and convenient.
