Aerobic internal circulation bio-separation reactor

Abstract

The invention provides an aerobic internal circulation bio-separation reactor. By arranging a partition plate, an aerobic reaction region and a settling region are combined, the land area is directlysaved, and a better choice is supplied to a sewage treatment station with the compact floor area; activated sludge is vertically and circularly moved in an equipment reactor, the motion height difference is large, the activated microbial activity is larger, and metabolism is faster; shallow aeration is adopted, operating pressure of power equipment can be saved, the model selection power of the power equipment is directly lowered, and the energy-saving effect is achieved; aerobic shallow aeration and inclined tube sedimentation are adopted to be combined, and the effluent quality is better; the aerobic internal circulation bio-separation reactor is more sufficient in aerobic reaction, the sludge age is prolonged, and the effluent quality is more limpid.

Description

technical field [0001] The invention relates to a sewage treatment device, in particular to an aerobic internal circulation biological separation reactor. Background technique [0002] According to the provisions of the National Environmental Protection Law, no matter whether it is domestic wastewater or industrial wastewater, it must be treated to meet the national standard before it can be discharged into natural water bodies. In the process of process selection, the most commonly used method is the aerobic biochemical method. Nowadays, the mature and commonly used aerobic biochemical methods include activated sludge method, contact oxidation method, biological filter method and so on. Most of these methods have the defects of long process flow, large floor area and unstable effluent quality. [0003] At present, for the activated sludge method, the sewage and various microbial groups are continuously mixed and cultivated under the condition of artificial oxygenation to f...

AI Technical Summary

Problems solved by technology

However, in the simple aeration process, sludge deposition needs to be dealt with, once the deposited activated sludge does not get enough oxygen, it will die

This will not only lead to the waste of active bacteria, but also fail to achieve the required effect of sewage treatment
