Abstract
The invention provides an integrated partial nitrosation-anaerobic ammonium oxidation slant plate enhanced bioreactor. The main structure of the bioreactor is cubic and is sequentially divided into anaerobic zone, a transition zone, an anaerobic zone, a diversion zone and a separation zone from left to right. The bioreactor includes a water inlet pipe, a compartment double-side water distributor,a micro-hole aeration pipe, an aerobic zone sludge draining pipe, a transition zone and anaerobic zone sludge draining pipe, a separation zone sludge draining pipe, a reflow pipe, an aerobic zone andtransition zone exhaust pipe, an anaerobic zone exhaust pipe, a separation zone exhaust pipe, a water outlet groove, a water outlet pipe, a baffle, a combined slant plate I, a combined slant plate IIand a slant plate. According to the bioreactor, autonomous deployment among the functional zones can be achieved, the poisoning influence of aeration on anaerobic functional microorganisms is completely avoided, the effect of separating sludge from water is greatly improved, and the overall nitrogen removal efficiency of the reactor is improved. The bioreactor has the following advantages that 1,the impact load resistance is high, and the floor space is small; 2, the influence of aeration on the performance of the reactor is avoided; 3, autonomous deployment of the functional zones is achieved; 4, the overall efficiency of the reactor is improved.
Description
technical field [0001] The invention relates to a biological autotrophic denitrification reactor for sewage, which belongs to the field of biological treatment for denitrification of sewage, in particular to an integrated partial nitrosation-anammox slant plate enhanced bioreactor. Background technique [0002] The Ministry of Environmental Protection pointed out in 2017 the environmental quality of surface water that ammonia nitrogen has become one of the main pollution indicators of surface water in my country. In recent years, the concentration of ammonia nitrogen discharged in the process of life and production has far exceeded the self-purification capacity of the receiving water body, which has become a major problem in the protection of my country's water environment. Ammonia nitrogen pollution will not only cause a series of environmental problems such as eutrophication of water bodies, but also a major hidden danger that threatens human health. [0003] When the tr...
