Description

Technical Field

[0001] The utility model relates to an assembled biological trickling filter box, which is used in the biological deodorization process of a sewage treatment plant. Background Art

[0002] The biological deodorization process of the sewage treatment plant is to treat the hydrogen sulfide, ammonia, pyrophosphate, mercaptan, skatole, propionic acid, butyric acid and other odorous gases volatilized in the sewage pool through pipelines and induced draft fans through alkaline washing, acid washing and biological trickling filtration adsorption reaction to achieve the purpose of degradation. The deodorizing biological trickling filter box is the core unit of this process. The traditional biological trickling filter box is made on site using fiberglass on-site production, and the civil engineering provides reinforced concrete foundation. The overall construction period is long, the quality is uneven, and the durability is poor. After being put into production, the odorous gases such as hydrogen sulfide, ammonia, pyrophosphate, mercaptan, skatole, propionic acid, butyric acid, etc. are volatilized in the sewage for a long time and the internal spraying wet environment is operated. The internal bracket keel of the traditional biological trickling filter box is easily corroded in this environment, and then the bracket breaks and even the top collapses, which makes the biological trickling filter box unable to be used normally, affecting the operation effect.
