Embodiment

[0051] Multistage aerobic enhanced phosphorus removal A according to the present invention P O-M process installed A in a decentralized sewage treatment plant in Shenzhen p O-M system, such as figure 2 shown.

[0052] Raw sewage 1 passes through coarse screen 2, lift pump 3, and fine screen 4, and then enters grit chamber 5 and fine screen 6 for pretreatment, reducing large particles and inorganic matter and increasing the biodegradability of sewage. The bar spacing of the coarse grid 2 is 20mm. The fine grid 4 is an internal inflow fine grid, which is a high-efficiency fine grid decontamination equipment that combines pollution prevention and decontamination, with a mesh size of 5mm and an installation angle of 90°. The residence time of sewage in the advection grit chamber 5 is 30s, and the effective water depth is 1.10m. The fine grid 6 is an internal flow fine grid with a mesh size of 1mm and an installation angle of 90°.

[0053] Subsequently, the sewage enters the ...

Abstract

The invention relates to a multistage aerobic enhanced phosphorus removal APO-M system. The system includes an anaerobic pool (AP), an aerobic pool (O) and an MBR pool (M). The anaerobic pool is communicated with the aerobic pool, the aerobic pool is communicated with the MBR pool, wherein the system also includes a chemical phosphorus removal agent adding device for adding of a chemical phosphorus removal agent into the MBR pool. The aerobic pool is used for aerobic treatment, including biological phosphorus removal, on sewage; the MBR pool is used for further aerobic treatment of sewage andchemical phosphorus removal treatment. The invention also relates to a multistage aerobic enhanced phosphorus removal APO-M technology adopting the system for simultaneous biological phosphorus removal and chemical phosphorus removal on sewage. The system and process provided by the invention can reach a high standard effluent level with a total phosphorus content of less than or equal to 0.2mg/L,and can achieve chemical phosphorus removal in the MBR pool, and have the advantages of space saving, investment saving and easy maintenance.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to a multi-stage aerobic enhanced phosphorus removal A P O-M system and process. Background technique [0002] With the growth of population, the modernization of industry and agriculture, and the development of urbanization, the amount of domestic sewage and industrial and agricultural wastewater is increasing day by day, which puts forward higher requirements for sewage treatment. With the deepening of urbanization and the improvement of infrastructure in my country, although the rate of sewage collection and treatment has increased, but due to the limitation of nitrogen and phosphorus removal technology in sewage treatment, the nitrogen and phosphorus indicators of the tail water of sewage treatment plants have always been affected. An important factor in the trophic level of water bodies. With the introduction of my country's "Water Pollution Prevention and Control Act...
