Description

Wastewater Treatment System{WASTE WATER TREATMENT SYSTEM}

The present invention relates to a wastewater treatment system, and more specifically, wastewater treatment capable of adjusting the salt concentration of wastewater flowing into the treatment tank to an appropriate level by mixing appropriate amounts of wastewater having various salt concentrations generated in various wastewater generating regions before treatment. It's about the system.

For the conservation of water quality in public waters, sewage, sewage, and wastewater (hereinafter referred to as'wastewater') discharged from homes, livestock farms, shopping malls, factories, etc. It must be purified and drained until it reaches the standards prescribed by the law. For this, methods such as solid/liquid separation, physicochemical treatment, and biological treatment are used depending on the type of wastewater or the substances contained therein.

The solid-liquid separation method is for separating and recovering suspended matter in wastewater, and it is inexpensive to process and easy to operate. The sedimentation separation method by gravity is the most widely used method, however, as opposed to gravity sedimentation, a method of naturally collecting injured objects on the surface of the water, or a forced separation method using the upward force of fine bubbles in the water generated by blowing or decompression Is also used.

Physicochemical treatment methods include neutralization/pH adjustment, oxidation/reduction, extraction, and adsorption. Neutralization/pH adjustment is to inject acid or alkali into the wastewater to release dissolved gas or to settle metal salts and adjust the pH to the most suitable for subsequent treatment. In addition to oxidation and reduction using chemicals, oxidation/reduction treatment is also performed by electrolysis and oxidative decomposition using ozone or ultraviolet light. Extraction is the recovery of useful substances present in the wastewater using a solvent, and adsorption is a method of treating various organic substances and ammonia in the wastewater with an adsorbent such as activated carbon or zeolite. In addition, ion exchange, electrodialysis, and treatment with reverse osmosis membranes are also a type of physicochemical treatment.

The biological treatment method is a method of decomposing or detoxifying contaminants in wastewater using bacteria, fungi, algae, protozoa, etc., and converting and removing organic substances in the form of carbon dioxide or methane gas. The biological treatment method is classified into a suspension method and a suspension method according to the type of contact between microorganisms and wastewater. In the suspended suspension method, microorganisms and wastewater are mixed, and the microorganisms are separated into treated water and microorganisms in a suspended suspension state, and then the microorganisms are returned to wastewater treatment. The fixing method includes a sprinkling furnace method, a rotating disk method, an immersion furnace method, a fluidized bed method, and the like, all of which have a fixed support for attaching microorganisms, so that only waste water passes through the surroundings of the fixing microorganism.

Physical and chemical treatments are disadvantageous in that they cause other types of environmental pollution because the operation cost is high due to consumption of chemicals, and the products after treatment must be reprocessed or disposed of, whereas biological treatments do not harm the natural environment much. There are advantages.

In the treatment of wastewater by biological treatment, the concentration of salt in the wastewater affects the efficiency of wastewater treatment. When the salt content in the wastewater is large, it affects the growth of microorganisms and treatment efficiency may decrease. In addition, even if the salt content in the wastewater is large, if the salt concentration is kept constant, the microorganisms can adapt to the environment and biological treatment is possible, but if the change in the salt concentration in the wastewater is large, the activity of the microorganism is greatly slowed.

However, since the conventional wastewater treatment system treats wastewaters of various salt concentrations generated in various wastewater sources as they are, it cannot actively cope with changes in the salt concentration of the wastewater flowing into the treatment tank, and the width of change in the salt concentration in the wastewater is large. There is a problem that processing efficiency is greatly reduced.

Specifically, the control unit 150 receives the salt concentration information of the wastewater collected from each of the plurality of water collecting unit salinity meters 112 to each wastewater collection facility 110, 120, 125, and the preset salt concentration calculation formula Accordingly, the flow rate of wastewater to be supplied to each salt collection tank 130 from each wastewater collection facility 110, 120, 125 is calculated. And by controlling the respective water collecting section pump 115 according to the time of reaching the wastewater from each wastewater collection facility (110) (120) (125) to the salt control tank 130, the salt control tank in each collecting section 111 The flow rate of the wastewater supplied to 130 is controlled. At this time, the control unit 150 controls the water collection unit pump 115 by receiving the flow rate information of the wastewater in real time from each water collection unit flowmeter 114, so that the amount of wastewater calculated in each water collection unit 111 is adjusted for salinity. It can be supplied to the tank 130.

In addition, the control unit 150 receives the salinity concentration information of the wastewater stored in the salinity control tank 130 in real time from the salinity control tank salinity meter 131, so that the salinity concentration of the wastewater in the salinity control tank 130 is a preset range. You can check whether it is maintained. Then, check whether the amount of wastewater supplied from each wastewater collection facility (110) (120) (125) calculated according to the calculation formula is appropriate, and each water collecting unit so that the salinity concentration of the wastewater in the salt control tank (130) is maintained in a preset range. The pump 115 can be readjusted.

In addition, the control unit 150 determines whether the water collecting unit salt meter 112 provided in each wastewater collection facility 110, 120, or 125 is abnormal by receiving a feedback signal from the salt control tank salt meter 131. can do. That is, when the salinity concentration of the wastewater in the salinity control tank 130 changes without changing the salinity concentration and the supply of wastewater in each wastewater collection facility 110, 120, 125, the control unit 150 It may be determined that an abnormality has occurred in the salinity meter 112 of the water collecting part. In this case, the manager can inspect and collect the salinity meter 112 of each wastewater collection facility 110, 120, 125, if necessary.

In addition, the control unit 150 receives each wastewater collection facility by receiving information on the amount of wastewater stored in each collection unit 111 from the water level sensor 113 of each wastewater collection facility 110, 120, 125 It is possible to check the amount of wastewater that can be directly supplied from (110) (120) (125). Then, depending on the amount of wastewater that can be directly supplied from each wastewater collection facility 110, 120, and 125, the salinity concentration range of the wastewater controlled by the salinity control tank 130 is reset to be supplied to the treatment tank 140. It is possible to keep the salt concentration in the wastewater as constant as possible.

In addition, the control unit 150 receives the water level information of the wastewater stored in the salt control tank 130 from the salt control tank water level sensor 132 and controls the salt control tank pump 133 to process it in the salt control tank 130 The flow rate of the wastewater flowing to the tank 140 can be adjusted. If the level of the wastewater in the salt control tank 130 is excessively low, it may be difficult to control the salt concentration of the wastewater in the salt control tank 130, so the control unit 150 moves from the salt control tank 130 to the treatment tank 140. The salt control tank pump 133 may be controlled to reduce the flow rate of the flowing wastewater.

The salt concentration of the wastewater can be adjusted within a certain range by mixing the wastewater from the collection facilities 110, 120, and 125 in an appropriate amount in the salt control tank 130. In addition, since the salinity control tank 130 supplies the wastewater with the adjusted salt concentration to the treatment tank 140, the salt concentration in the treatment tank 140 is maintained by keeping the salt concentration change width of the wastewater flowing into the treatment tank 140 small. It is possible to prevent the degradation of the activity of microorganisms, and as a result, it is possible to increase the efficiency of wastewater treatment in the treatment tank 140.

A plurality of desalination tanks 230 are arranged in series along the sub-wastewater flow path 220, and an intermediate valve 233 is installed between the plurality of desalination tanks 230 to regulate the flow of wastewater. The intermediate valve 233 is controlled by the control unit 150. The connection path 235 is connected to the remaining salt removal tank 230 except for the salt removal tank 230 disposed at the downstream of the flow path of the wastewater passing through the sub wastewater flow path 220 among the plurality of salt removal tanks 230. Is connected. The connection path 235 connects the salt removal tank 230 and the treatment tank 140 to enable the flow of wastewater. The connection path 235 is provided with a connection path valve 237 for controlling the flow of wastewater through the connection path 235. Connection valve 237 is controlled by the control unit 150. When the sub-waste water flow path valve 225 opens the flow path of the sub-waste water flow path 220, the waste water flowing along the sub-waste water flow path 220 passes through one or a plurality of desalination tanks 230 in turn to be treated. It may be introduced into the tank 140. As such, the flow path of the wastewater flowing along the sub-wastewater flow path 220 may be controlled by the controller 150.

The control unit 150 detects signals from the water collecting part salinity meter 112, the water collecting part water level sensor 113, and the water collecting part flow meter 114 provided in the plurality of wastewater collection facilities 110, 120, and 125, respectively.

The operation of the control unit 150 is as described above.

In addition, when the salt concentration of the wastewater stored in the salt control tank 130 inevitably exceeds a preset range, the controller 150 passes the wastewater discharged from the salt control tank 130 through the salt removal tank 230. By doing so, the salt concentration of the wastewater supplied to the treatment tank 140 can be lowered.

Supply. In this case, the number of desalination tanks 230 through which the wastewater passes may be changed according to an excess range of the salinity concentration of the wastewater discharged from the salinity control tank 130. In other words, the larger the excess range of the salt concentration of the wastewater discharged from the salt control tank 130 is, the more the wastewater passes through the salt removal tank 230 which is sequentially disposed along the sub-wastewater flow path 220. It can be made to flow to the processing tank 140.

For example, when the excess range of the salt concentration of the wastewater discharged from the salt control tank 130 is not large, the controller 150 passes only the first salt removal tank 230 of the sub-wastewater flow path 220. It can be made to flow to the treatment tank 140.

On the other hand, when the excess range of the salt concentration of the wastewater discharged from the salt control tank 130 is large, the control unit 150 passes through all the salt removal tanks 230 disposed along the sub-wastewater flow path 220 It can be made to flow to the processing tank 140. To this end, the control unit 150 controls to open and operate all the intermediate valves 233 on the sub-wastewater flow path 220, and connects the connection paths 235 connected to the first and second desalination tanks 230, respectively. The valve 237 is controlled to close the flow path of the connection path 235. At this time, the wastewater flowing along the sub-wastewater flow path 220 passes through the first desalination tank 230, the second desalination tank 230, and the third desalination tank 230 in order to remove salt. It can flow to the post-treatment tank 140.

As such, the control unit 150 changes the number of the salt removal tanks 230 through which the wastewater passes according to an excess range of the salt concentration of the wastewater discharged from the salt control tank 130, thereby flowing into the treatment tank 140. It is possible to keep the change in the salt concentration of the wastewater small.

The wastewater purified by the treatment tank 140 may pass through the precipitation tank 145 and be discharged to the outside.

In this embodiment, the number of desalination tanks 230 disposed in the sub-wastewater flow path 220 may be variously changed. In the drawing, a plurality of desalination tanks 230 are shown to be arranged in series on one sub-wastewater flow path 220, but in another variant, a plurality of desalination tanks 230 are salt control tanks 130 ) And the treatment tank 140 may be arranged in parallel through a plurality of sub wastewater flow paths 220. In this case, the size of each salt removal tank 230 is different, or the salt removal of each salt removal tank 230 is performed through a method of disposing the absorption member 231 having different adsorption performance in each salt removal tank 230 Performance may vary. And by flowing the wastewater to the salt removal tank 230 having a suitable salt removal performance among a plurality of salt removal tank 230 according to the excess range of the salt concentration of the wastewater discharged from the salt control tank 130, the treatment tank 140 ), it is possible to keep the width of the salt concentration change of the wastewater flowing in small.
