Abstract

The invention discloses an efficient aeration tank for sewage treatment. The efficient aeration tank comprises a tank body; the top of the tank body is provided with a portal frame; the inner top of the portal frame is provided with a motor, and an output shaft of the motor is connected with a rotating shaft; a plurality of supporting frames are equidistantly fixed on the inner cavity wall of thetank body in a vertical direction; and stirring parts are arranged between every two of the supporting frames. The rotating shaft drives an aeration plate to rotate in a working process of the efficient aeration tank, so that air bubbles are more uniformly distributed in the tank body, and the aeration efficiency is increased; the air bubbles can move along inclined surfaces of guide plates in anupward floating process, so that the staying time of the air bubbles in the tank body is prolonged to ensure that sewage is in more sufficient contact with the air bubbles, and the aeration efficiencyis increased; and elastically connected blades can stretch out and draw back under the actions of a centrifugal force and a water flow, so that the stirring range is continuously changed, the turbulence effect of the sewage is improved, furthermore, the sewage is sufficiently mixed with air, and the aeration efficiency is increased.

Description

technical field [0001] The invention relates to an aeration tank, in particular to a high-efficiency aeration tank for 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. 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] Most of the mechanical agitation components in the existing aeration tanks have a singl...
