Aeration system of biochemical sewage treatment tank

Abstract

The invention provides an aeration system of a biochemical sewage treatment tank. The aeration system comprises a biochemical aeration tank, a stirring device arranged at the bottom of the biochemicalaeration tank, a plurality of aerator assemblies symmetrically arranged on the inner wall of the biochemical aeration tank, an air blowing unit and an upper computer. The air blowing unit is connected with the aerator assemblies through a pipeline system and at least comprises an air blowing device, a plurality of aerators arranged on an aeration prepressing pipe uniformly and a plurality of dissolved oxygen testers arranged on the aeration prepressing pipe, each air blowing device is connected with the corresponding aerator assembly through a first electric binary valve connection pipeline A, and the upper computer is connected with the stirring device, the air blowing devices and the dissolved oxygen testers. Compared with the conventional technology, the aeration system has the advantages that dissolved oxygen content in the biochemical aeration tank is tested in real time by arranging the dissolved oxygen testers, and oxygen content in the biochemical aeration tank is ensured to be within a stable range by controlling start and stop of the air blowing devices and flow to reach needs of microorganisms on oxygen.

Description

technical field [0001] The invention relates to the technical field of biochemical sewage treatment, in particular to an aeration technology for a biochemical sewage treatment pool, in particular to an aeration system for a biochemical sewage treatment pool. Background technique [0002] At present, the biochemical aeration system of the water treatment biofilm method generally adopts the aeration method of installing the aeration disc at the bottom. This installation method makes it extremely troublesome when maintenance is required, and the entire biochemical tank needs to be emptied, causing the system to fail to operate. Maintenance costs have also increased significantly. In addition, the amount of aeration in the rear section of the general biochemical tank does not need to be large, so the number of aeration pans installed will also be reduced in terms of process requirements. In this way, the installation interval of the aeration pans is large, so that some biofilm b...

AI Technical Summary

Problems solved by technology

[0005] In the above, although the sludge can be cleaned through disassembly, the cleaning of the biochemical aeration tank is very complicated. Even if it can be disassembled and cleaned, the actual effect is not very prominent. Every disassembly requires complicated cleaning work. Fulfill actual requirements

At the same time, the biochemical aeration tank is prone to sludge accumulation, and the cleaning work is more cumbersome
