Sewage treatment aeration basin with function of improving aeration efficiency

Abstract

The invention discloses a sewage treatment aeration basin with a function of improving the aeration efficiency. The sewage treatment aeration basin comprises a basin, a rotary shaft, an aeration plateand a motor. A mounting frame is fixed to the top of the basin; the top of the rotary shaft is rotationally connected onto the inner top surface of the mounting frame, and the lower end of the rotaryshaft extends into the basin and extends to the bottom of the basin; the aeration plate is fixed to the center of the bottom of the basin and is hollowly arranged, and gas outlet holes are uniformlyformed in the top of the aeration plate; fixed rods are connected with the bottom of the rotary shaft, and foam breaking blades are arranged at the bottoms of the fixed rods; an upper slide sleeve anda lower slide sleeve are fittingly connected onto the rotary shaft, movable rods are connected onto the lower slide sleeve, a spiral slide rail is arranged on a cavity wall in the middle of the basin, and slide sheets which are matched with the spiral slide rail are arranged on the movable rods; aeration vanes are arranged on the upper slide sleeve, and airbags are arranged at the bottoms of theaeration vanes. The sewage treatment aeration basin has the advantages that aeration stirring can be simultaneously carried out on sewage at the bottom, in the middle and on surface layers of the basin when the sewage treatment aeration basin works, and excellent aeration effects can be realized by the sewage treatment aeration basin.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an aeration tank for sewage treatment with improved aeration efficiency. 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. The aeration tank uses the activated sludge method for sewage treatment, and 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 sewage and activated sludge. The aeration tank is mainly composed of three parts: the tank body, the aeration system and the water inlet and outlet. The pool body is generally made of reinforced concrete, and its planar shape is rectangular, square and circular. [0003] The stirring structure of the existing aeration tank is...

AI Technical Summary

Problems solved by technology

[0003] The mixing structure of the existing aeration tank is relatively simple, which leads to low aeration efficiency and cannot meet the growing needs of people for sewage treatment.
