Problems solved by technology
The activated sludge method and its improved process still have problems such as insufficient biomass, low utilization rate of filler, and insufficient utilization of the separated area of the reactor; the suspended filler is mainly made of high-molecular organic substances such as polyethylene, polypropylene, and polyurethane, which has anti- Pressure, corrosion resistance, abrasion resistance, aging resistance, etc., but at the same time, it also has the disadvantages of poor hydrophilicity and biophilicity, resulting in slow film-forming speed and small amount of film-forming of fillers, which affects the overall sewage treatment efficiency.

Abstract
The invention discloses a domestic sewage treatment system comprising an anaerobic treatment system, an aerobic treatment system, a precipitation system, a disinfection system, a sludge storage systemand a power distribution room; the anaerobic treatment system is additionally provided with a filler baffle plate and a rotary filler box, so that the contact time and area of domestic sewage and filler are increased, and the starting time is shortened; an underflow stirrer is additionally arranged, so that the problems of short flow, dead corner and the like are reduced; the volumes of compartments of a reactor are different, and the degradation efficiency is improved by utilizing the difference of microbial communities; according to the aerobic treatment system, a flow baffle is additionally arranged, the dissolved oxygen amount is increased in a mechanical mode, and the operation cost is saved; the different-wave baffle plate is utilized, so that the inflow retention time is prolonged,the surface of the baffle plate is rough, a film is easy to form on the baffle plate, and the treatment efficiency is improved; by adding a modified combined suspended filler, the film culturing efficiency of the filler is improved. The invention also discloses a method for treating domestic sewage by using the domestic sewage treatment system, biochemical treatment is carried out in the whole process, no chemical is added, and secondary pollution is reduced.
Description
technical field [0001] The invention belongs to the technical field of domestic sewage treatment technology, and in particular relates to a domestic sewage treatment system and a method for using the domestic sewage treatment system. Background technique [0002] The anaerobic baffled reactor was improved and developed by researchers such as McCarty of Stanford University in the United States when they studied the anaerobic biological turntable reactor, referred to as ABR (Anaerobic Baffled Reactor). Because the reactor has many advantages such as good composite flow state, simple structure, strong bio-retention capacity, high efficiency and stability, it has become one of the research hotspots of wastewater anaerobic biological treatment technology. But the baffles of the reactor in the prior art only play the role of baffles and are not fully utilized; and according to the research, the microbial community structure, pH value and the products of organic matter in each comp...
