A biological trickling filter tower for organic waste gas treatment and its use method

Abstract

The invention discloses a biological trickling filter tower for treating organic waste gas and a method for using the same, belonging to the field of biological trickling filter towers, a biological trickling filter tower for treating organic waste gas and a method for using the same. In the process of circulating through the hollow cone filler, it not only realizes the function of providing nutrients for the biofilm, but also has the effect of flushing the excess biofilm in the main filter material and the secondary filter material. Compared with the existing technology , the present invention realizes the synchronous process of waste gas purification and excess biofilm flushing, while ensuring the continuous and stable purification efficiency, it saves the process of cleaning excess biofilm, and solves the problem of excessive biofilm propagation in the prior art. Purification efficiency is a problem, and the present invention provides a secondary adsorption carrier for excess biofilm by setting carrier collection balls, so that while maintaining a certain purity of the nutrient aqueous solution, it provides convenience for collecting excess biofilm.

Description

technical field [0001] The invention relates to the field of biological trickling filter towers, in particular to a biological trickling filter tower used for treating organic waste gas and a method for using the same. 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. Studies at home and abroad have shown that the use of biological trickling filtration to purify low-concentration organic waste gas is economical, practical, and efficient. It has the advantages of low equipment investment costs, low operating costs, easy operation, thorough treatment, and no secondary pollution. It is especially suitable for It can treat organic waste gas with poor water solubility (benzene, toluen...

AI Technical Summary

Problems solved by technology

[0006] In view of the problems existing in the prior art, the object of the present invention is to provide a biological trickling filter tower for organic waste gas treatment and its use method, which realizes both The function of providing nutrients for the biofilm also has the effect of flushing the excess biofilm in the main filter material and the secondary filter material. Compared with the prior art, the present invention realizes the synchronous cleaning of waste gas and excess biofilm flushing process, while ensuring the continuous and stable purification efficiency, the process of cleaning the excess biofilm is omitted, which solves the problem in the prior art that the excessive growth of biofilm blocks the filler and affects the purification efficiency. Collecting the ball provides a secondary adsorption carrier for the excess biofilm, keeping the nutrient solution at a certain purity, and at the same time providing convenience for collecting the excess biofilm
