described CASS Waste Water Treatment, also has one group of B401-2 blower fan in described Ventilator Room.
beneficial effect:
1. the CASS Sewage treatment systems of the present invention's design and method are to develop and next on the basis of intermittent activated sludge process (SBR method), and it is in CASS reaction tank front portion, to be provided with biological selecting area, and rear portion is provided with liftable automatic draining device.Its working process can be divided into aeration, precipitation and draining three phases, and loop cycle is carried out.Cyclic activated sludge system divides pre-reaction zone and main reaction region.In pre-reaction zone, microorganism can be adsorbed rapidly most of dissolved organic matter in sewage by the fast transfer mechanism of enzyme, the matrix Rapid Accumulation process of a high loading of experience, this plays good shock absorption to influent quality, the water yield, PH and hazardous and noxious substances, hyphomycetic growth is played to restraining effect simultaneously, can effectively prevent sludge bulking; In main reaction region, experience subsequently one compared with the substrate degradation process of underload.Cyclic activated sludge system integrates reaction, precipitation, draining, function, the degraded of pollutent is a plug-flow process in time, microorganism among aerobic, anoxic, anaerobism periodical change, thereby reach pollutant removal effect, also there is good denitrogenation, phosphorus removal functional simultaneously.Through simulation test research, cyclic activated sludge system has been successfully applied to the improvement of sanitary sewage, food wastewater, pharmacy waste water, and obtained good treatment effect sewage and entered continuously pre-reaction zone, through partition wall bottom, enter main reaction region, guaranteeing, under the condition of oxygen supply, to make organism by the microbiological deterioration in pond.According to influent quality, can adjust operating parameter.
2. construction cost of the present invention is low, has saved primary sedimentation pond, secondary sedimentation basins and sludge reflux equipment, and construction cost can save 20%-30%.Technical process is simple, and Sewage Plant main units is water collecting basin, settling pit, CAS aeration tank, sludge sump, and compact in design reduces floor space; Save working cost, because aeration is that periodically in pond, the concentration of dissolved oxygen also changes, precipitate phase and bleeding stage dissolved oxygen reduce, and while restarting aeration, oxygen concentration gradient is large, transfer efficiency is high, and energy-saving effect is remarkable, and working cost can save 10%-25%; Organic removal rate is high, and effluent quality is good, can not only effectively remove organic carbon source pollutent in sewage, and has good denitrogenation dephosphorizing function; Management is simple, reliable, is difficult for occurring sludge bulking, sewage work's device category and comparatively small amt, and Controlling System is simple, safe and reliable to operation; Sludge yield is low, and stable in properties is convenient to further process and dispose.
