Efficient aeration tank

Abstract

The invention discloses an efficient aeration tank which comprises a tank wall, a bracket, a motor, a transmission shaft, an aeration plate, a blower, a water inlet pipe and a drain pipe, wherein the bracket is fixedly connected with the upside of the tank wall; the lower surface of the bracket is fixedly connected with the motor; a shaft extension end of the motor is fixedly connected with the transmission shaft; a right rotating shaft is rotationally connected with an inner wall on the right side of the tank wall; a left rotating shaft is rotationally connected with an inner wall on the left side of the tank wall; stirring plates are fixed on the left rotating shaft and the right rotating shaft; the tail end of the transmission shaft is fixedly connected with the upper surface of the aeration plate; sewage in a middle layer is turned over vertically by the stirring plates; the sewage and air are mixed more uniformly; the aeration plate exhausts the air into the sewage in a rotating process for aeration of the sewage; the aeration plate exhausts the air while rotating; the air and the sewage are mixed more intensively; the stirring rod scatters bubbles exhausted by the aeration plate; the contact area between the air and the sewage is increased; and an aeration effect is further improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to a high-efficiency aeration tank. Background technique [0002] The aeration tank is a structure that uses the activated sludge method for sewage treatment. A certain sewage residence time is provided in the tank to meet the oxygen required by aerobic microorganisms and the mixing conditions for full contact between the sewage and the activated sludge. The aeration tank is mainly composed of the tank body It consists of three parts, the aeration system and the water inlet and outlet. The pool body is generally made of reinforced concrete, and the plane shape is rectangular, square and circular. The existing aeration methods are mainly divided into blast aeration and mechanical aeration. The existing aeration tanks often have relatively single aeration mechanism and low aeration efficiency, which makes it difficult to meet people's increasing demand for sewage tr...
