Gas inlet self-stirring type biological washing tower for waste gas treatment

Abstract

The invention discloses a gas inlet self-stirring type biological washing tower for waste gas treatment and belongs to the field of biological washing towers. The gas inlet self-stirring type biological washing tower for waste gas treatment comprises a tower body, the inner wall of the tower body is fixedly connected with an upper fixed plate and a lower fixed plate which are parallel to each other; the upper fixed plate is positioned on the upper side of the lower fixed plate; activated sludge is contained at the upper end of the lower fixed plate; waste gas is diffused by adopting the row gas diffusion soft columns, wherein the waste gas washing and biological reaction processes are carried out in the tower body together; so that the occupied equipment is significantly reduced, exhaust gas treatment cost is reduced, and high economic benefit is achieved. Compared with the prior art, waste gas diffusion is performed through the row gas diffusion soft columns, and double stirring of activated sludge and biological suspension liquid is realized, so that the activated sludge and the biological suspension liquid are always in a dynamic environment, sufficient contact between microorganisms and pollutants is realized, the reaction efficiency is greatly improved, and the device has an excellent practical effect.

Description

technical field [0001] The invention relates to the field of biological scrubbers, in particular to an intake self-stirring biological scrubber for waste gas treatment. Background technique [0002] The number and types of low-concentration organic waste gases emitted from various production processes are increasing day by day. These low-concentration organic waste gases contain a variety of volatile organic compounds (VOCs), which seriously pollute the air and endanger human health and the ecological environment. The principle of biological treatment of waste gas is to use microorganisms to digest and metabolize the pollutants in the waste gas. It is essentially an oxidative decomposition process. It absorbs VOCs through active microorganisms attached to the medium and converts pollutants into harmless water. , carbon dioxide and other inorganic salts. There are three commonly used biological treatment methods for organic waste gas: biological trickling filter tower, biolo...

AI Technical Summary

Problems solved by technology

[0004] However, the existing method of using a biological scrubber to treat waste gas involves a lot of equipment and high cost, and because the activated sludge tank is always in a static state, it is difficult for the microorganisms in it to fully contact with the pollutants in the liquid phase to decompose , making the decomposition efficiency lower
