Problems solved by technology

Among the currently used devices, there are large and medium bubble aerators such as perforated tubes, Jinshan I type, diffuse flow, etc., which are characterized in that the gas is pressed out from the external air device to form a stream of air, resulting in a large diameter of the bubbles, and gas, liquid, etc. The contact area is small and the utilization rate of oxygen is low. When the microporous air distribution plate made of titanium plate or ceramic plate is used, the micropores are easy to be blocked. After the micropores are blocked, it cannot provide sufficient dissolved oxygen and relatively low oxygen consumption. A good flow rate state reduces the effect of biochemical treatment of sewage. In order to prevent the clogging of micropores, the gas is usually purified first. However, the micropores on the microporous gas distribution plate will still be blocked after working for a period of time. , so it needs to be cleaned with three acids regularly, which not only increases people's troubles, but also artificially causes secondary pollution
In some special occasions, it is necessary to use the aerator in a horizontal state, so the general aeration device cannot meet people's requirements

Abstract

The invention relates to a diaphragm type hole-variable aerator which comprises a tray and an upper cover connected with the tray in a matching way, wherein the upper cover is provided with a synthetic rubber diaphragm with high elasticity, the synthetic rubber diaphragm with high elasticity is provided with a self closing hole with 150 micrometer to 200 micrometer hole diameter, the aerator is arranged on an ABS (Acrylonitrile Butadiene Styrene) air pipe, and the two ends of the ABS air pipe are provided with a level governor. The diaphragm type hole-variable aerator provided by the invention has the advantages of favorable use effect and small daily maintenance quantity, and moreover the diaphragm type hole-variable aerator is provided with the level governor.

Description

technical field [0001] The invention relates to an aeration device used in biochemical sewage treatment, in particular to a microporous aerator. Background technique [0002] The variable hole aerator is an ideal energy-saving aeration device for biochemical wastewater treatment in papermaking, textile, petroleum, chemical and medical fields. Among the currently used devices, there are large and medium bubble aerators such as perforated tubes, Jinshan I type, diffuse flow, etc., which are characterized in that the gas is pressed out from the external air device to form a stream of air, resulting in a large diameter of the bubbles, and gas, liquid, etc. The contact area is small and the utilization rate of oxygen is low. When the microporous air distribution plate made of titanium plate or ceramic plate is used, the micropores are easy to be blocked. After the micropores are blocked, it cannot provide sufficient dissolved oxygen and relatively low oxygen consumption. A good ...
