A non-clogging microporous aeration system

Abstract

The invention relates to the technical field of microporous aeration systems, in particular to a non-blocking microporous aeration system, comprising an air inlet pipe, a distribution pipe is fixedly connected to the lower end of the air inlet pipe, and a uniformly distributed aeration pipe is connected to the distribution pipe Aeration pipe, one end of the aeration pipe away from the distribution pipe is provided with a sealing plate, and the aeration pipe is provided with an aeration part, and the pipe body corresponding to the aeration part is provided with evenly distributed micropores, the aeration pipe A first collar and a second collar are sleeved on the upper part, a circular tubular waterproof cloth is connected between the second collar and the side wall of the sealing plate, and the waterproof cloth is sleeved on the outside of the aeration pipe, so the The material of the second ring is metal iron, and the end of the first ring close to the second ring is fixedly installed with an electromagnet. Cover it, and then use clean water to replace the water between the tarpaulin and the aeration pipe. At this time, the air source can be closed normally, and impurities will not block the pores.

Description

technical field [0001] The invention relates to the technical field of microporous aeration systems, in particular to a non-clogging microporous aeration system. Background technique [0002] Sewage treatment refers to the measures taken to change the nature of sewage so that it does not cause harm to environmental waters. Sewage treatment is generally divided into three levels: primary treatment, which uses physical treatment to remove insoluble pollutants and parasite eggs; secondary treatment, which uses biological treatment to oxidatively degrade various complex organic substances in sewage into Simple substances; tertiary treatment, which uses chemical precipitation, biochemical, physical and chemical methods, etc., to remove phosphorus, nitrogen, refractory organic matter, inorganic salts, etc. in sewage. The biochemical process is mainly carried out under the condition of sufficient oxygen supply in the aeration tank. Due to the metabolic activity of aerobic bacteria...

AI Technical Summary

Problems solved by technology

In order to prevent the sludge from clogging the aeration holes, when the microporous aerator is not aerating, the outer cover blocks the aeration micropores under the action of gravity, so the aeration head can only be set in the multi-row microporous aerator. The upper side of the air pipe cannot make full use of the working area of ​​the multi-row microporous aeration pipe; in addition, the aeration hole cannot completely prevent sludge from entering, and it is not easy to disassemble for internal sludge cleaning after long-term use and blockage
