Abstract

The invention discloses an aeration device for urban sewage treatment; the aeration device includes an aeration chamber, a motor, a floc removing mechanism, an aeration disc and a swing plate. The upper end of the aeration chamber is equipped with a motor, the output end of the motor is fixedly connected with a stirring shaft, and the lower end of the stirring shaft penetrates through the upper end of the aeration chamber, stretches to the interior of the aeration chamber and is fixedly connected with a crankshaft; the lower end of the inner side of the aeration chamber is fixedly connected with a supporting rod; the aeration disc is arranged below the supporting rod, and the upper end of the aeration disc is articulated with a plurality of aeration heads; the aeration heads penetrate through a sleeve, and the sleeve is rotatably connected on the supporting rod; the floc removing mechanism includes a reflux pipe, a circulation pump and a filter chamber. The design is novel; the aeration heads are driven to swing when the arranged aeration disc moves left and right, so that the aeration range of the aeration heads is increased and the aeration effect is increased; flocs produced inthe aeration chamber can be cleared through the arranged floc removing mechanism, so the treatment effect of sewage is improved.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an aeration device for urban sewage treatment. Background technique [0002] The problem of water pollution is an environmental problem throughout the world. According to the methods used in sewage treatment, it can be divided into four types: physical method, chemical method, physical chemical method and biological method. Biological method is a method of using the metabolism of microorganisms in wastewater to decompose degradable organic matter in sewage. Because of its large processing capacity, low investment, and economical reliability, it has become the most common water treatment method in the world today. [0003] The aeration tank is a device for biochemical treatment of sewage. After the sewage enters the aeration tank, it reacts organically with the active mud in the tank, and the harmful substances are decomposed into harmless substances, which are discharged after th...
