Description
Technical field
The utility model relates to a kind of sewage disposal device, in particular to a kind of micro-hole aerator for sewage treatment.
Background technique
In sewage disposal process, it is often necessary to air is injected into sewage using the aerator being located on gas distributing pipeline,
It is dissolved in the oxygen in air rapidly and uniformly in sewage, current common aerator has micro-hole aerator, jet aerator etc.,
The features such as stable structure of micro-hole aerator, uniform aeration, is widely applied it, and existing micro-hole aerator is by holding in the palm
Plate, the flat micro-pore aeration film for being located at supporting plate surface and air inlet pipe composition, air enter aeration by air inlet pipe from gas distributing pipeline
It in device, expands micro-pore aeration film under the influence of air pressure and heaves, until micropore opens, air is diffused to by the micropore opened
In sewage, sewage is flow backwards in order to prevent, and many aeration plates are equipped with check-valves in air inlet pipe, but the setting of check-valves increases gas
The resistance of stream causes certain pressure loss, also increases the manufacturing cost of enterprise, and such aerator is located at since aeration film is flat
The upper surface of supporting plate, for aeration film when heaving, the space between aeration film surrounding and supporting plate is smaller, the bullet that the micropore of surrounding generates
Property deformation it is also less, such air enters in sewage from the micropore in the middle part of diaphragm mostly, cause air flow method uneven so that expose
The diminution of gas area generates certain plasticity in addition, the micropore on aeration film is easily deformed fatigue during constantly contracting
Deformation causes micropore to shrink defective tightness when stopping aeration, leads to sewage infiltration or sludge blockage.
In view of this, the present inventor furthers investigate described problem, there is this case generation then.
Utility model content
Micropore contraction is even closer when the utility model provides a kind of stopping aeration, prevents sewage from flowing backwards, and is aerated space-time
The aerator that gas can uniformly be spread.
In order to realize the purpose, the utility model adopts the following technical solution:
