Abstract

The invention relates to the technical field of sewage treatment, and discloses an aeration tank for urban sewage treatment. The aeration tank comprises a tank body, the left side of the surface of the tank body is fixedly connected with an air pump; the output end of the air pump is fixedly connected with a main pipe communicating with the air pump. A rotatable flow blocking arc plate is matchedwith a counterweight filter box to constrain gas exhausted from a gas guide hole; it is ensured that long term staying of the gas in water for reaction with sewage is realized; when a certain volume of reacted gas is accumulated, the gas is released; the aeration time is greatly prolonged; aeration effect is improved, a bending pad and the counterweight filter box are arranged on the flow blockingarc plate; solid substances in sewage can be buffered and prevented from colliding with the flow blocking arc plate along with movement of gas, the solid substances can be brought into the counterweight filter box through the gas along the flow blocking arc plate to be filtered out, the service life of the flow blocking arc plate and the stability of the whole device are effectively guaranteed, and the sewage treatment efficiency can be improved.

Description

technical field

[0001] The invention relates to the technical field of sewage treatment, in particular to an aeration tank for urban sewage treatment. Background technique

[0002] The aeration tank is a biochemical reactor designed according to the characteristics of microorganisms. The degree of degradation of organic pollutants mainly depends on the aeration reaction conditions designed by people. It mainly uses the activated sludge method for sewage treatment, and a certain amount of sewage is provided in the tank. The residence time satisfies the oxygen required by aerobic microorganisms and the mixing conditions of full contact between sewage and activated sludge. In order to improve the effect of aeration, it is necessary to reduce the size of the bubbles as much as possible, increase the number of bubbles, and increase the degree of turbulence of the liquid. , Increase the installation depth of the aerator and prolong the contact time between the bubbles and the liqu...
