Aeration tank with double aeration structure

Abstract

The invention discloses an aeration tank with a double aeration structure. The aeration tank comprises a tank body, a fixing frame, an aeration plate, a draining pipe and an air blower, the top of thetank body is fixedly connected with the fixing frame, a first motor is fixedly connected on the upper surface of the fixing frame, a shaft extending end of the first motor is fixedly connected with aturnplate, a limiting sleeve is fixedly connected on the lower surface of the fixing frame, a sliding rod penetrates from the inside of the limiting sleeve, a rotating shaft is arranged on each of left and right sides of the sliding rod, the aeration plate is arranged at the bottom of the tank body, and the inside of the aeration plate is hollow. The air blower is utilized to deliver air to the aeration plate to aerate sewage; a stirring rod is utilized to stir the sewage to break bubbles in the sewage, so that the sewage and the air are mixed more uniformly, and aeration is more uniform; a stirring plate is utilized to stir the sewage on the surface layer to lift the sewage, so that the sewage and the air can fully contact; a brushing plate is utilized to brush an aeration nozzle on theaeration plate to prevent the aeration nozzle from being blocked; the aeration plate is utilized to drive the sewage on the bottom layer to turn over upwards, so that the aeration process is more uniform.

Description

technical field [0001] The invention relates to the field of sewage treatment equipment, in particular to an aeration tank with a double aeration structure. 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 pool 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 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, the mixing of sewage and air is not sufficient, the aeration efficiency is low, and it is diffic...
