Description

Technical Field

[0001] The utility model belongs to the technical field of sewage deodorization, and particularly relates to a sewage deodorization device for sewage treatment plants. Background Technique

[0002] During the sewage treatment process, due to the large amount of organic substances and chemical substances in the sewage, a large amount of malodorous gases, such as hydrogen sulfide, ammonia, etc., are often generated, seriously affecting the surrounding environment and the lives of residents.

[0003] Most of the existing deodorization devices are relatively fixed beside the sewage treatment equipment, occupying a large area. The staff cannot move the deodorization device randomly and can only deodorize specific sewage treatment equipment. Once the sewage treatment equipment cannot operate, the deodorization device will also stop, resulting in a certain waste of resources. Moreover, some deodorization devices have limited removal effects on malodorous gases and poor deodorization effects. Content of the Utility Model
