Detailed description of the invention
In order to preferably this utility model is illustrated, elaborate below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of system for reducing sludge of sewage treatment plant amount, including inlet channel 1, pretreatment pool 3, biochemistry pool 7, sedimentation tank 10, sludge condensation 13, water pump 16, wherein inlet channel 1 is connected with pretreatment pool 3, between inlet channel 1 and pretreatment pool 3, it is provided with grid 2, grid 2 is set in pretreatment pool 3 front end, removes big suspended material, sewage enters pretreatment pool 3 through grid 2, carries out the regulation of the water yield, water quality etc..Pretreatment pool 3 is connected with the macromolecule organic degradation biological bacterium incubator 4 being arranged on its side.Biological bacteria effect is processed by efficient waste water fermentation, the Organic substance of macromolecule difficult degradation is changed into the Organic substance that low molecule is easily degraded, improves the biodegradability of sewage, simultaneously work as the regulation effect of the water yield, water quality, reduce the impact to biochemistry pool, strengthen the disposal ability of biochemical system.
The outlet pipe 5 of pretreatment pool is connected with biochemistry pool 7, biochemistry pool 7 processes biological bacteria incubator 8 with the activated state waste water being arranged on its side and is connected, efficient activated state waste water is coordinated to process biological bacteria, can be with the COD in fast degradation, removal sewage, ammonia nitrogen etc., improve effluent quality, reduce by more than 40% sludge yield；Simultaneously because adding of biological bacteria, add the Quantityanddiversity of microorganism in biochemical system, enhance the shock resistance of system, anti-fluctuation ability.
The outlet pipe 9 of biochemistry pool is connected with sedimentation tank 10, and biochemistry pool 7 sewage out enters sedimentation tank 10, carries out mud, water separation in sedimentation tank 10, and the supernatant is discharged by being located at the outer comb 12 above sedimentation tank 10.Being additionally provided with return duct 6 between biochemistry pool 7 and sedimentation tank 10, return duct 6 is connected with the outlet pipe 5 of pretreatment pool, and an activated sludge part for lower floor enters biochemical system front end by return duct 6, so ensures that the part of contaminated water of backflow is fully degraded at biochemistry pool 7.Residue point then enters sludge concentration tank, waits and further being processed.
The discharge pipeline 11 of sedimentation tank is connected with sludge concentration tank 13, and sludge concentration tank 13 is connected with the sewage disposal biological bacteria incubator 14 being arranged on its side.After excess sludge enters sludge concentration tank 13, by the nitrification and denitrification process intercoupled between biological bacteria, remove the ammonia nitrogen in mud and oxygen consumption organic, simultaneously by being enriched in the transduction of the microfauna food chain of mud oxide layer, quickly cut down mud.
The outlet pipe 15 of sludge concentration tank connects with water pump 16, and the outlet pipe 17 of water pump connects with pretreatment pool 3.Process the mud after biological bacteria is decomposed through waste water in sludge concentration tank 13, aqueous mixtures is processed to pretreatment pool 3 again by 16 dozens, water pump, and the whole process of system can make mud decrement reach more than 90%.
Above-mentioned detailed description of the invention is not construed as further restriction of the present utility model, and the unsubstantiality change that those skilled in the art make according to this utility model content all should fall in this utility model protection domain.
