A biological filter deodorization device for sewage treatment plant

Abstract

The invention discloses a biological filter deodorization device used in a sewage treatment plant, and relates to the technical field of odor treatment. The invention includes a deodorizing box and a microbial decomposition layer, the microbial decomposition layer is fixed on the inner wall of the deodorizing box, an air intake pipe is fixedly connected to an outer side wall of the deodorizing box below the microbial decomposition layer, and an air suction pump is fixedly installed on the air intake pipe The top surface of the deodorant box is also fixed with an exhaust sleeve, and a plurality of microbial decomposition layers are arranged in parallel along the vertical direction; Below the deflector; the attachment plate and the deflector are partially overlapped on the same vertical plane, and the side of the attachment plate farther from the center of the deodorizing box extends to the outside of the deflector and is connected to the side of the deodorizing box. on the inner wall. When the present invention is used, the odor can be fully decomposed, the internal temperature can be easily controlled, the overall structure is convenient, and the secondary pollution of water can be effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of odor treatment, in particular to a biological filter deodorization device for sewage treatment plants, which is mainly used for the decomposition of odor generated in sewage treatment. Background technique [0002] In the daily operation of the sewage treatment plant, a large amount of odor will be produced in the sewage, which will cause great pollution to the air. With the improvement of people's environmental requirements, the odor problem of sewage treatment has been put on the agenda. The most common treatment process for the odor in sewage is the microbial deodorization method, which decomposes the organic waste gas through microorganisms to achieve deodorization; [0003] As in the existing publications, CN206404587U-Biofilter deodorization device, which discloses a tower body and a fan connected to the tower body through an input pipe, a partition plate is vertically arranged inside the tower body...

Problems solved by technology

[0010] The purpose of the present invention is to provide a biological filter deodorization device for sewage treatment plants with good odor decomposition effect, easy control of internal temperature, convenient structure and avoiding secondary pollution of water. The gas decomposition efficiency is low, the internal temperature is difficult to control, the overall structure is complex, and it is easy to cause secondary pollution of water
