Adopt such scheme, grid are mainly used in the preliminary removal to bulk foreign material in water after sewage network accesses sewage work; The breeding wastewater stirred in the agitated pool that catchments is extracted in waste water baffle-box, waste water in waste water baffle-box flows from top to down along filter screen in screw extrusion press, in this process, most water is walked by filter screen filter, water flows on the base plate of lower box, flow out from the water outlet at the lower box back side, the water that water outlet flows out enters preliminary sedimentation tank and carries out just heavy adjustment hydrolysis acidification pool.
Slag inclusion waste water enters auger sleeve from opening for feed, unnecessary water flows in cabinet from the permeable hole of auger lower cartridge again, under the effect of screw auger, slag constantly enters the extension of auger sleeve, slag is squeezed when entering the extension of auger sleeve, a small amount of waste water flows to sewage collecting box from the permeable hole of extension again, and the wastewater outlet of this sewage collecting box is connected with waste water baffle-box, again enters next circulation.Excrement slag then from slag notch out, enters fertilizer workshop.
Just the heavy hydrolysis acidification pool Main Function that regulates is runoff investigation and the tiny foreign material of preliminary precipitation, ensures that follow-up water treatment building normally runs. also play the function of larger molecular organics in acidication waste water.IC reactor decomposing organic matter, and a large amount of COD, BOD removed in waste water produces the reaction unit of biogas.After IC reactor, liquid enters one-level anoxic pond and one-level Aerobic Pond, utilize the pond of microbiological deterioration organism process, in anoxic pond, denitrifying bacterium utilizes the organism carbon source in waste water, be that nitrogen is discharged in air by bringing a large amount of nitrate-nitrogen reduction in backflow mixed liquor into, therefore, BOD declines, and nitrate declines.
Acidic substance during first alkali lye pond is used for and in water, make water be weakly alkaline, are conducive to microbial growth.Improve the efficiency of aerobic reaction.
In one-level Aerobic Pond, organism is degraded by microbial biochemical and continues to decline, and organonitrogen is by ammonification and then nitrated, be ammonia nitrogen concentration decline, but along with digestive process be nitrate increase, P is along with the excessive extraction of polyP bacteria, enter in bacterium, P content in sewage is declined.
One-level Aerobic Pond water out enters medium sediment pool, again precipitates, the excess sludge in removing Aerobic Pond, makes pond, front end remain active.
Intermediate sedimentation pond secondary anoxic pond and secondary Aerobic Pond react further, and more the process of plus depth remaining COD, BOD, makes water quality be cleaned further, process in rear end to polyP bacteria simultaneously.Second alkali lye pond is also to regulate pH, makes applicable microbial growth, improves the efficiency of aerobic treatment.
From secondary Aerobic Pond out after, enter Calcified pond and flocculation basin and dephosphorization settling tank, the unnecessary polyP bacteria produced processed, the polyP bacteria of excessive suction phosphorus is removed from waste water, thus reaches the function of dephosphorization; Simultaneously to remaining excess sludge of generation precipitation.And by adding acid for adjusting pH, improve effluent quality.
Finally enter the double oxygen pool.Effect utilizes the microorganism in pool and algae to carry out a biological disposal upon to sewage and organic waste water, carries out waste water evolution, purify water further by " bath bacterium cogeneration system " in pool.This water quality is just recoverable after sterilization.
In such scheme: described sludge gas collecting device comprises methane purifying system (61) and biogas storage system (62).
