A self-cleaning aeration tank with scrubbing function

Abstract

The invention discloses a self-cleaning aeration tank with a scrubbing function, comprising a tank body, a fixed frame, an aeration blade, an aeration disc, a water inlet pipe and a drain pipe, and the top of the tank body is fixedly connected with a fixed frame , the inside of the pool body is provided with a stirring shaft, the left outer wall of the pool body is fixedly connected with a second motor, the left end of the stirring shaft is covered with a first bevel gear, the right end of the stirring shaft is also covered with a sleeve, and the sleeve is covered with There is a second bevel gear, a third bevel gear is set between the first bevel gear and the second bevel gear, and the upper and lower sides of the sleeve are symmetrically installed with cleaning frames, the sewage is injected into the pool through the water inlet pipe, and the air is blown by the blower. Discharge into the sewage at the bottom, and aerate the sewage at the bottom. While aerating, the aeration disc rotates, so that the air bubbles can be discharged into the sewage more evenly, so that the sewage and the air bubbles are evenly mixed, and the bristles are used to aerate the upper surface of the aeration disc. The surface is brushed to prevent the aerator head from being blocked by sludge, which saves the trouble of manually cleaning the aeration disk.

Description

technical field [0001] The invention relates to an environmental protection device, in particular to a self-cleaning aeration tank with a scrubbing function. Background technique [0002] In sewage treatment, the activated sludge method is often used to treat sewage. The activated sludge method uses activated sludge containing a large number of microorganisms to absorb and oxidize and decompose organic or inorganic pollutants in sewage, so that sewage can be purified. . Due to the large water treatment capacity and high efficiency of this method, it has been widely used in various sewage treatment. The activated sludge method is an aerobic biological treatment method. At present, the following aeration methods are often used: ordinary aeration method, gradual reduction aeration method, adsorption regeneration aeration method, complete mixed aeration method, etc. However, during the aeration process of the existing aeration device, the activated sludge and impurities in th...
