Biological filter deodorization device for sewage treatment plant

Abstract

The invention discloses a biological filter deodorization device for a sewage treatment plant, and relates to the technical field of odor treatment. The device comprises a deodorization box and a plurality of microbial decomposition layers, the microbial decomposition layers are fixedly arranged on the inner wall of the deodorization box, an air inlet pipe is fixedly connected to one outer side wall of the deodorization box below the microbial decomposition layers, an air pump is fixedly mounted on the air inlet pipe, an exhaust sleeve is further fixedly arranged on the top surface of the deodorization box, and the multiple microbial decomposition layers are arranged side by side in the vertical direction; and each microbial decomposition layer comprises two attachment plates and a guide plate, the two attachment plates are symmetrically arranged below the guide plate, the attachment plates and the flow guide plate are partially overlapped on the same vertical plane, and one sides, far away from the center position of the deodorization box, of the attachment plates extend to the outer side of the flow guide plate and are connected to the inner wall of the deodorization box. During use, odor can be fully decomposed, the internal temperature is easy to control, the overall structure is convenient, and secondary pollution of water can be effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of odor treatment, and in particular relates to a biological filter deodorization device for sewage treatment plants, which is mainly used for the decomposition of odor produced in sewage treatment. Background technique [0002] In the daily operation of sewage treatment plants, a large amount of odor will be produced in sewage, which will bring great pollution to the air. With the improvement of people's environmental requirements, the problem of odor in sewage treatment has been put on the agenda. For the odor in the sewage, the more common treatment process is the microbial deodorization method, which decomposes the organic waste gas through microorganisms to achieve deodorization; [0003] Such as the existing public documents, CN206404587U-biological filter deodorization device, discloses a fan that includes a tower body and is connected with the tower body through an input pipeline, and the inside of t...

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
