Disc-type micropore aerator

Abstract

The invention discloses a disc-type micropore aerator including a flow guide disc, a rubber membrane sheet and a plurality of gas guide pipes; the middle part of the flow guide disc is provided with a hollow flow guide pipe protruding out of the upper surface of the flow guide disc, the end part of the upper end of the flow guide disc is in a sealing state, and the side wall surface of the upper end is provided with a plurality of gas guide holes; the central area of the rubber membrane sheet is a non-pore area, and the periphery area is provided with a plurality of micropores penetrating through the rubber membrane sheet; the rubber membrane sheet is positioned above the flow guide disc, the periphery edge of the rubber membrane sheet and the periphery edge of the flow guide disc are in sealing connection, and a gas guide cavity is formed between the flow guide disc and the rubber membrane sheet; the plurality of gas guide pipes are each of an V shape, one end of each of the plurality of gas guide pipes is connected with one of the plurality of gas guide holes, the side wall of the other end of each of the plurality of gas guide pipes is provided with a gas outlet hole, the gas outlet direction is that a gas flow sprays to a part of the central area of the rubber membrane sheet, and the gas outlet holes are each provided with a non-return valve. The device cannot cause pollution of ventilation pipelines.

Description

technical field [0001] The invention relates to the field of sewage treatment equipment, in particular to a disc microporous aerator. Background technique [0002] Among the many methods of sewage treatment, aerobic biological treatment is an economical and effective method. There are many factors that affect the effect of aerobic biological treatment. One of the important factors is that there must be sufficient dissolved oxygen in sewage, aeration The device is a key device for supplying oxygen to sewage. [0003] And in existing microporous aerator, the pipeline that carries out ventilation is generally designed bigger, although check valve has been arranged in the device, still have sewage to carry out to ventilation pipeline in the moment that check valve is closed, like this, along with The accumulation of sewage in the ventilation pipe will cause the pollution of the ventilation pipe. Contents of the invention [0004] The present invention aims to overcome the te...
