Aeration device with flocculate removing function

Abstract

The invention discloses an aeration device with a flocculate removing function. The aeration device comprises an aeration cavity, a motor, a circulating mechanism and a blower, wherein the motor is arranged at the upper end of the aeration cavity; an output shaft of the motor is fixedly connected with a rotating shaft; a threaded rod positioned at the lower end of the inner side of the aeration cavity is in threaded connection with a movable disk; rotating rods are symmetrically arranged at the left end and the right end of the movable disk; one end of each rotating rod is rotationally connected with the movable disk; the other end of each rotating rod is rotationally arranged in a rack cavity; the circulating mechanism comprises a reflux pipe, a circulating pump and a filtering cavity; two ends of the reflux pipe are respectively communicated with the left end side wall of the aeration cavity; the circulating pump and the filtering cavity are both communicated with the reflux pipe; afilter screen is arranged on the inner side of the filtering cavity; a one-way valve is arranged on the reflux pipe at the lower end. The aeration device disclosed by the invention adopts a novel design; flocculates generated in the aeration cavity can be removed by the arranged circulating mechanism, so that the sewage treating effect is improved.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an aeration device with the function of removing flocculation. 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 dis...

AI Technical Summary

Problems solved by technology

Ordinary aeration devices have a single method, which makes the aeration tank insufficient, resulting in incomplete sewage treatment. During the aeration process, more flocs are produced, which will also affect the sewage aeration effect
