Problems solved by technology

[0003] However, the disadvantages of the existing ordered batch activated sludge sewage treatment method are: the utilization rate of the intermittent aeration reaction tank is reduced, the treatment process is unstable, the rated air volume and power of the aeration blower are high, and the installation is relatively complicated. Inlet gate valve and automatic control system, etc.
[0005] Although the above-mentioned No. 97116662.5 patent overcomes the defects of the prior art, since

Abstract

A process for treating sewage by aeration and biologically removing phosphorus includes an aerobic phosphorus releasing stage, continuous aerating and excessive picking-up phosphorus stage, intermittent aerating and organic substance removing stage, and two deposition stages. Its apparatus is composed of the serially connected anaerobic reaction pool, continuous aerating reaction pool and intermittent aerating reaction pool.

Description

technical field [0001] The invention relates to a sewage treatment method and equipment, in particular to a continuous intermittent aeration sequence batch sewage treatment method and equipment with biological phosphorus removal. Background technique [0002] At present, the activated sludge method is generally used for sewage treatment, and the activated sludge method is a biological method for sewage treatment using the metabolic process of certain microorganisms in activated sludge. The specific treatment methods mainly include: continuous reaction type and sequence batch type. Sequencing batch activated sludge process is a kind of sewage treatment process that has been developed long ago. Its reaction mechanism and decontamination mechanism are basically the same as those of continuous reactive activated sludge process, but the treatment process and equipment are different from those of continuous reactive activated sludge process. There is a big difference. A typical ...
