Problems solved by technology

Due to the large population of our country and the large differences between regions, the process and equipment selection of the sewage treatment plants to be built are very different. The most typical one is A 2 O process and SBR process, the aeration equipment used includes surface aerator and bottom blowing microporous aerator equipment, etc., the existing aeration equipment has certain limitations and specificity, and some equipment has been Therefore, the development of a multi-purpose aeration equipment with strong adaptability and compliance with various process requirements and characteristics will play a key role and have far-reaching significance for my country's sewage treatment industry.

Abstract

Disclosed is a panel-type microporous aerator, comprising an arc-shaped panel (1), a resistance-free check valve (2), a rubber aeration film (3), a V-shaped pressing strip (4) and a plug-connection bottom plate (5). The top portion of the arc-shaped panel (1) is an arc-shaped plate (101). An installation hole for installing the resistance-free check valve (2) is disposed at a certain interval along a length of the arc-shaped plate (101), and an air distribution channel (102) is disposed beneath the arc-shaped plate (101). A body (203) of the resistance-free check valve (2) is disposed inside the air distribution channel (102), and a valve member (201) of the resistance-free check valve (2) is disposed on top of the arc-shaped plate (101). The arc-shaped plate (101) and the valve member (201) of the resistance-free check valve (2) are covered by the rubber aeration film (3). An anti-slipping strip (302) provided at either side of the rubber aeration film (3) is fastened inside a V-shaped groove (103) of the arc-shaped panel (1) by the V-shaped pressing strip (4), wherein the V-shaped groove (103) is provided with a protrusion.

Description

technical field [0001] The invention belongs to the field of aeration devices and relates to a slat type microporous aerator. Background technique [0002] Since the beginning of the 21st century, with the development of my country's industry and the improvement of people's living standards, environmental problems have increasingly affected people's lives, especially the cost of energy consumption for sewage treatment, purification and treatment is also rising . At the same time, our country has invested a lot of money and built a large number of urban and industrial sewage treatment plants. Due to the large population of our country and the large differences between regions, the process and equipment selection of the sewage treatment plants to be built are very different. The most typical one is A 2 O process and SBR process, the aeration equipment used includes surface aerator and bottom blowing microporous aerator equipment, etc. The existing aeration equipment has certa...
