High-efficiency aeration tank for treating domestic sewage

Abstract

The invention discloses a high-efficiency aeration tank for treating domestic sewage. The high-efficiency aeration tank comprises a tank body, a blower, an air hose, a water inlet pipe and a drain pipe, wherein a supporting frame is fixedly connected to the top of the tank body; a motor is fixedly connected to the lower surface of the supporting frame; a rotating shaft is fixedly connected to a shaft extending end of the motor; a stirring rod is fixedly connected to the rotating shaft; the other end of the stirring rod is fixedly connected with a magnetic rod; an upper stirring plate and a lower stirring plate are hinged to a side wall of the tank body; the magnetic rod is positioned between the upper stirring plate and the lower stirring plate; a left aeration plate and a right aeration plate are arranged at the bottom of the tank body; the blower is fixedly connected to the outer side wall of the tank body; the left aeration plate and the right aeration plate move leftward and rightward in a horizontal direction during aeration to ensure that air and bottom layer sewage are mixed more fully; the stirring rod is used for stirring the sewage to ensure that the air and the sewage are mixed more fully; the upper stirring plate and the lower stirring plate keep rotating up and down to ensure that the air and the sewage are mixed more fully; aeration blades are used for performing aeration on surface layer sewage.

Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to a high-efficiency aeration tank for domestic sewage treatment. Background technique [0002] The aeration tank is a structure that uses the activated sludge method for sewage treatment. It is generally used for the preliminary treatment of sewage. The mixing condition of activated sludge fully contacting. The aeration tank is mainly composed of three parts: the tank body, the aeration system and the water inlet and outlet. The aeration methods are mainly divided into blast aeration and mechanical aeration. The existing aeration tanks often have a relatively single aeration mechanism, long aeration time, and low aeration efficiency, which are difficult to meet people's growing sewage treatment needs. . Contents of the invention [0003] The object of the present invention is to provide a high-efficiency aeration tank for domestic sewage treatment, so as to solve the problems raise...
