An aeration system for a biochemical sewage treatment pond

Abstract

The invention provides an aeration system for a biochemical sewage treatment tank, comprising a biochemical aeration tank, a stirring device arranged at the bottom of the biochemical aeration tank, and several aerators symmetrically arranged on the inner wall of the biochemical aeration tank Assembly, a blower unit, connected to the aerator assembly through a pipeline system, the blower unit includes at least one set of blower devices, and the blower device is connected to the aerator assembly through an electric two-point valve connecting pipe A , several well-arranged aerators arranged on the aeration pre-pressure pipe and several dissolved oxygen measuring instruments arranged on the aeration pre-pressure pipe, a host computer, and the stirring device, the blowing device and the dissolved oxygen measurement The instruments are connected separately. Compared with the traditional technology, the present invention measures the dissolved oxygen content in the biochemical aeration tank in real time by setting the dissolved oxygen measuring instrument, and ensures the oxygen in the biochemical aeration tank by controlling the opening and closing and flow control of the blower device. The content is in a stable range, which meets the needs of microorganisms for 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...

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
