Lifting aeration device capable of automatic cleaning in sewage treatment

Abstract

The invention discloses a lifting aeration device capable of automatic cleaning in sewage treatment. The lifting aeration device comprises a gas inlet main pipe, a gas distribution pipe, a gas distributing converter and an aerator; a gas inlet main valve and a slag hole valve are arranged at the two ends of the gas inlet main pipe correspondingly, the gas inlet main pipe is provided with a water injection branch way and a gas distribution branch way, and the water injection branch way is provided with a water injection opening valve; the first end of the gas distribution pipe is in flange connection with the gas distribution branch way; the gas inlet end of the gas distributing converter is in flange connection with the second end of the gas distribution pipe; and the gas inlet end of theaerator is in flange connection with the gas outlet end of the gas distributing converter. Compared with the prior art, under the situation that a transformed water pool is full of water, the aerationdevice can be mounted easily, conveniently and quickly, blockage of aerator micropores is automatically cleaned, single set of broken-down aeration can be conveniently lifted and maintained in the later period, the application range is wide, management operation is easy, and operation is stable.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a liftable aeration device for automatic cleaning in sewage treatment. Background technique [0002] The aeration tank in the sewage treatment system is a bioreactor that provides the survival of activated sludge. Air is filled through the aeration equipment to bring enough oxygen into the mixed solution containing activated sludge to make it produce aerobic metabolic reaction. The aeration equipment not only provides oxygen to the mixed liquid, but also acts as agitator to keep the mixed liquid in a suspended state. In this way, the organic matter, oxygen in the mixed liquid and the microorganisms in the activated sludge can be fully mass-transferred and reacted. [0003] The design and working conditions of the aeration system determine the energy consumption and treatment effect of the activated sludge process. Most of the traditional aeration equipment belongs to b...

AI Technical Summary

Problems solved by technology

Most of the traditional aeration equipment belongs to blast aeration, and aeration is performed by fixing the aerator on the bottom of the pool, and such aeration equipment is very prone to failure of the aeration element

The more complicated situation is that when maintenance or replacement is required, the workshop must stop production without drainage and the aeration tank must be emptied.

This will affect the production of the enterprise, thereby affecting the benefits of the enterprise. It is a project that is not worth the candle

At present, there are improved aeration equipment on the market that can be lifted, but there are still cases where the aerator cannot be aerated due to the clogging of the aerator after long-term use

Replacing and rebuilding at this time, although the equipment can be upgraded, is still a huge amount of work when the aeration tank is full of water, which consumes manpower, material resources and precious time of the production company.
