Embodiment Construction
[0011] Below, in conjunction with specific embodiment, the present invention is further described:
[0012] A microbial treatment method for urban sewage, including primary filtration, secondary filtration, multi-bacteria group reaction, gas collection and sedimentation anti-virus, primary filtration: the bulk impurities in the sewage flowing into the grit chamber are filtered through a multi-stage filter. Intercepting with suspended solids, the mesh of the filter screen gradually decreases along the sewage inflow direction, and there are sewage outlets between each filter screen, so as to reduce the filtration pressure of the grit chamber, facilitate the classification of impurities inside the sewage, and facilitate the sewage circulation.
[0013] Secondary filtration: The sewage is passed into the grit chamber, and the secondary treatment of the sewage is completed by removing the heavy sand particles in the sewage, and then removing the suspended solids, and then enters th...

Abstract
The invention provides an urban sewage microbiological treatment method comprising primary filtration, secondary filtration, multi-flora reaction, gas collection and precipitation sterilizing. Large impurities and suspended solids in sewage flowing into a grit chamber are intercepted through a multi-stage filter screen, the sewage is introduced into the grit chamber, sand grains with large specific gravity and suspended solids in the sewage are removed, and transverse aeration pipes and vertical aeration pipes are laid in a multi-flora reaction tank. A turbofan is mounted in an area enclosed between the transverse aeration pipe and the vertical aeration pipe, firstly, air is blown to perform an aerobic bacteria decomposition reaction, the amount of the introduced air is determined according to the measured organic matter content, the multi-flora reaction tank performs an anaerobic reaction and anaerobic bacteria fermentation, and gas generated by the reaction is collected through a gas conveying pipeline; and a gas flow meter is mounted on the gas conveying pipeline, when the flow is greatly reduced, the anaerobic reaction and gas collection are stopped, and sewage is introduced into the grit chamber to be subjected to precipitation disinfection. The method is high in sewage treatment efficiency, economical and environment-friendly.
Description
technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a microbial treatment method for urban sewage. Background technique [0002] Water pollution and water shortage are one of the serious environmental problems facing our country. The direct discharge of a large amount of sewage not only destroys ecology, exacerbates water shortages, but also seriously endangers industrial and agricultural production and human health and safety. At present, the continuous flow treatment of urban sewage at home and abroad mainly adopts the activated sludge method, and the devices used are composed of grids, grit chambers, anaerobic reaction tanks, anoxic reaction tanks, aerobic reaction tanks and sedimentation tanks. Among them, the anaerobic reaction tank, the anoxic reaction tank and the aerobic reaction tank are square tanks. The reaction tank has an inlet pipe and an outlet pipe. The water inlet pipe of the anaerobic reaction tank is c...
