Industrial sewage aeration device with double-stirring mechanism

Abstract

The invention discloses an industrial sewage aeration device with a double-stirring mechanism. The industrial sewage aeration device comprises a tank body, a fixing rack, a driving shaft, stirring blades, an aeration plate, a water inlet tube and a water discharge tube, wherein the fixing rack is fixedly connected with the top of the tank body; a telescopic mechanism is fixedly connected with thelower surface of the fixing rack; a fixing plate is fixedly connected with the lower end of the telescopic mechanism; a stirring motor is fixedly connected with the lower surface of the fixing plate;the driving shaft is fixedly connected with a shaft extension end of the stirring motor; a driven shaft is arranged on the right side of the driving shaft; the aeration plate is arranged at the bottomof the tank body. In the aeration process, the aeration plate is moved leftwards and rightwards, then bubbles can be relatively uniformly discharged into sewage, the sewage can be relatively uniformly mixed with the bubbles, the aeration efficiency can be improved, sewage at the bottom of the tank body is pumped out by using a circulation water pump and is sprayed back into the tank body througha nozzle, then the sewage can contact the air sufficiently, the sewage is subjected to circulated aeration, relatively sufficient sewage aeration can be achieved, and due to adoption of the two stirring shafts, namely the driving shaft and the driven shaft, sewage can be relatively sufficiently mixed with bubbles.

Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to an industrial sewage aeration device with double stirring mechanisms. Background technique [0002] The random discharge of industrial sewage will have a great negative impact on the environment. At present, people often use aeration tanks to treat sewage. The aeration tank is a structure that uses activated sludge method for sewage treatment. Air system and water inlet and outlet are composed of three parts. The pool body is generally built with reinforced concrete, and its planar shape is rectangular, square and circular; aeration is a means to make air and water come into strong contact, and its purpose is to dissolve oxygen in the air in water. The aeration structure of the aeration device is single, and the mixing of sewage and air is not sufficient, resulting in low aeration efficiency, and it is difficult to meet people's growing sewage treatment needs.
