Description
Technical Field
The utility model relates to a water treatment system, in particular to an acetate wastewater treatment system.
Background
The A/O process is a biological method combining oxygen deficiency and oxygen deficiency to treat total nitrogen and COD in sewage, and has the advantages of high efficiency, simple flow and the like, but most of the traditional treatment devices are straight-through type, and water is drained after anaerobic treatment, aerobic treatment and sedimentation are sequentially completed, so that the total nitrogen utilization rate and the nitrogen and phosphorus removal rate need to be considered, the time of each process needs to be prolonged, the treatment period is long, and the treatment cost is relatively increased.
Disclosure of Invention
The utility model provides an acetate effluent disposal system with simple structure and effective compromise of treatment efficiency, period and cost.
The utility model adopts the technical proposal that: the utility model provides an acetate effluent disposal system which characterized in that: including the sewage house steward, the anaerobic treatment pond, the aerobic treatment pond, the sedimentation tank, the outlet pipe, the mud squeezer, squeeze the wet return, good oxygen wet return, deposit the wet return, the sewage house steward connects the anaerobic treatment pond in proper order, good oxygen treatment pond, the sedimentation tank, the outlet pipe is connect on sedimentation tank upper portion, the sedimentation tank lower part connects the mud squeezer through the pump through the mud pipe, the mud squeezer connects the sedimentation tank through squeezing the wet return pipe, good oxygen treatment pond, the sedimentation tank bottom is respectively through good oxygen wet return, deposit the wet return and connect to the sewage house steward on.
Further, the sludge discharge pipe is connected with a sludge concentration tank, and the sludge concentration tank is connected with a sludge presser through a pump.
Furthermore, the upper part of the sedimentation tank is divided into two paths, one path is connected out, and the other path is connected back to the aerobic treatment tank through a water outlet pipe by a pump.
Furthermore, the sewage main pipe, the water outlet pipe and the water outlet pipe are all provided with a stop switch valve.
Furthermore, a carbon source adding box is arranged on the anaerobic treatment tank, and the aerobic treatment tank is internally connected with an aeration pipe.
Furthermore, the sewage main pipe, the water outlet pipe and the water outlet pipe are all provided with flow meters.
The utility model discloses improve the structure that the through-type was handled in proper order with the tradition, pass through the flowmeter control return volume with effectual heterotrophic bacterium in good oxygen processing pond, the sedimentation tank, thereby it sends into the anaerobic treatment pond to merge to return to the sewage house steward, thereby combine the anaerobic treatment pond to add the carbon source, the sewage squeezer squeezes the return water sedimentation tank, when can compromise total nitrogen utilization ratio, nitrogen and phosphorus removal rate, the processing time of each process is controllable relatively shortens, be favorable to shortening treatment cycle, reduce cost.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: the system comprises a sewage main pipe 1, an anaerobic treatment tank 2, a carbon source adding box 3, an aerobic treatment tank 4, an aeration pipe 5, a sedimentation tank 6, a water outlet pipe 7, a sludge discharge pipe 8, a sludge presser 9, a squeezing water return pipe 10, an aerobic water return pipe 11, a sedimentation water return pipe 12, a stop switch valve 13 and a flowmeter 14.
Detailed Description
The following further description is made in conjunction with the accompanying drawings and examples.
FIG. 1 shows: an acetate wastewater treatment system comprises a main sewage pipe 1, an anaerobic treatment tank 2, a carbon source adding box 3, an aerobic treatment tank 4, an aeration pipe 5, a sedimentation tank 6, a water outlet pipe 7, a sludge discharge pipe 8, a sludge presser 9, a squeezing water return pipe 10, an aerobic water return pipe 11, a sedimentation water return pipe 12, a stop switch valve 13 and a flowmeter 14.
The sewage main pipe 1 is sequentially connected with an anaerobic treatment tank 2, an aerobic treatment tank 4 and a sedimentation tank 6, a carbon source adding box 3 is arranged on the anaerobic treatment tank, an aeration pipe 5 is connected in the aerobic treatment tank, the upper part of the sedimentation tank 6 is connected with a water outlet pipe, the lower part of the sedimentation tank is connected with a sludge squeezer 9 through a sludge discharge pipe 8 and a pump, the sludge squeezer is connected with the sedimentation tank through a squeezing return pipe 10, and the bottoms of the aerobic treatment tank and the sedimentation tank are respectively connected with the sewage main pipe 1 through an aerobic return pipe 11 and a sedimentation return pipe 12; a stop switch valve 13 and a flow meter 14 are arranged on the aerobic water return pipe 11 and the sedimentation water return pipe 12.
In order to further improve the sewage treatment and sedimentation efficiency, the sludge discharge pipe is connected with the sludge concentration tank, the sludge concentration tank is connected with the sludge squeezer through the pump, heterotrophic bacteria can further react in the sludge concentration tank conveniently, and then the sludge squeezer squeezes and squeezes the water return pipe to return to the sedimentation tank, so that the improvement of the treatment efficiency is facilitated.
