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

Embodiment Construction

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the implementation manners in the present invention, all other implementation manners obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0019] Such as figure 1 shown, combined with figure 2 , the aerobic internal circulation biological separation reactor of the present invention comprises a reaction vessel 1, a mud bucket 2, a water inlet cylinder 3, a mud discharge pipe 4, an aeration head 5, a partition plate 6, an overflow weir 7, an isolation cylinder 8 and an inclined Tube 9.

[0020] The reaction vessel 1 provides space for reaction and circulation...

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...
