Aerator

Abstract

The invention relates to an aeration cylinder, and belongs to the field of sewage treatment equipment technology. The aeration cylinder comprises an installation support (1), one end of the installation support (1) is provided with an aeration cylindrical shell (3) at a vertical direction, and the cross section of the aeration cylindrical shell (3) is in polygon shape; multiple aeration blocks (4) are arranged in the polygon shaped aeration cylindrical shell (3) from top to bottom, and the multiple aeration blocks (4) are spirally arranged in an inner wall of the aeration cylindrical shell (3); an air supply pipe (2) is arranged on the installation support (1) at a horizontal direction, the air supply pipe (2) and the aeration cylindrical shell (3) are connected, and air outlet of the air supply pipe (2) is located below multiple aeration blocks (4). The aeration cylinder solves the blockage problem and greatly reduces power consumption; rolling, stirring and other fine treatment are carried out for sludge which is introduced into the aeration cylinder and air, so that dissolving efficiency is improved and cleaning treatment is realized at the same time.

Description

technical field [0001] The invention relates to an aeration cylinder, which belongs to the technical field of sewage treatment equipment. Background technique [0002] At present, biological treatment is the main method of sewage treatment, which can be divided into activated sludge method and biofilm method. Due to the mature technology and reliable equipment, the activated sludge method is widely used in large-scale sewage treatment plants, but it has problems of unstable operation in small and medium-sized sewage treatment, prone to sludge bulking, and high energy consumption. The main forms of biofilm method are biofilter, biological turntable and biological contact oxidation method, etc., which are mostly used for small and medium-sized sewage treatment. Due to the characteristics of high treatment efficiency, convenient maintenance and management, and low operating costs, the biological turntable has been widely used in the treatment of small and medium-sized domestic...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the above disadvantages and provide an aerator, which does not need to worry about clogging and can greatly reduce power consumption. The sludge is introduced into the aerator and air is tumbling and stirred for micronization, which improves the dissolution efficiency and at the same time Achieved cleaning
