Abstract

The invention discloses an ultramicropore aerator for sewage treatment. The ultramicropore aerator comprises an aeration disc, an aeration tube and an air pipeline, wherein a support base is arranged below the aeration disc; one end of the aeration tube is communicated with the aeration disc through a central hole of the support base; an aerator base is arranged on the air pipeline; the other end of the aeration tube is communicated with the air pipeline through the aerator base; a sealing ring is arranged at the joint of the aeration disc and the support base; the aeration disc is provided with uniformly distributed aeration pores; the apertures of the aeration pores range from 50-75 mu m; and the aeration tube and the aerator base are in threaded connection. Compared with a common micropore aerator, the ultramicropore aerator is greatly improved in oxygenation property, and has the advantages of high working continuity, good material quality, good stability and the like.

Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to an ultra-microporous aerator for sewage treatment, which belongs to the technical field of sewage treatment. Background technique [0002] The aeration system of the sewage treatment plant is the largest energy-consuming link, accounting for about 50-70% of the total energy consumption. Improving the oxygenation performance of the aerator is the most effective way to reduce the energy consumption of the aeration system in the sewage treatment plant. Therefore, it is very necessary to develop high-performance microporous aerators. [0003] At present, the pore size of microporous aerators widely used in sewage treatment plants is generally between 150-200 μm. The size of the air bubbles produced by the aerator is determined by the pore size. Generally speaking, the smaller the bubble, the larger the gas-liquid contact area, which is conducive to oxygen mass transfer. However, the ...
