Anti-blocking aeration device for sewage treatment

Abstract

The invention discloses an anti-blocking aeration device for sewage treatment. The aeration device comprises an aeration chamber, a motor, a rotating shaft, aeration tubes and brushing mechanisms; themotor is arranged at the middle position of the upper end of the aeration chamber, the output end of the motor is fixedly connected with the rotating shaft, the rotating shaft goes through the uppercover plate of the aeration chamber, extends into the aeration chamber and is fixedly connected with the upper end of a crankshaft, and the lower end of the crankshaft is rotatably connected to the bottom of the aeration chamber; the aeration tubes are symmetrically mounted at the inner lower end of the aeration chamber, and aeration heads are symmetrically mounted at the upper end and the lower end of every aeration tube; and the brushing mechanisms are arranged at the outer sides of the aeration tubes. The device has a novel design, the downwardly arranged aeration heads deliver a gas, and the gas has a moving impact force, so the sewage at the bottom of the aeration chamber can be thoroughly aerated; the aeration heads are brushed with brush hair in the reciprocating movement process ofcleaning brushes on the aeration tubes to prevent generated floc from blocking the aeration heads and affecting the aeration effect; and the device also has a strong practicability, and is worth promoting.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to an aeration device for sewage treatment with an anti-clogging function. 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...

AI Technical Summary

Problems solved by technology

Ordinary aeration devices have a single means, so that the aeration tank is not fully aerated, resulting in incomplete sewage treatment. During the aeration process, more flocs are produced, which is easy to block the aeration head and affect the aeration effect.
