Abstract

The invention discloses a novel deodorant for a sewage treatment plant. The novel deodorant is prepared from, by weight, 8-10 parts of a sanitizer, 3-8 parts of sodium hydroxide, 10-20 parts of granular active carbon, 1-3 parts of ethylene glycol, 4-8 parts of magnesium aluminum silicate, 20-40 parts of zinc oxide, 3-5 parts of sodium pyrophosphate, 3-8 parts of talcum powder and 0.1-0.3 part of essence. Compared with the prior art, the novel deodorant has the advantages that odor can be effectively removed, the disinfection effect is achieved, the operation cost is greatly lowered, and the practicability is high; the preparation technology is simple, and the cost is low.

Description

technical field [0001] The invention relates to the field of environmental protection. More specifically, the present invention relates to a novel deodorant for use in sewage treatment plants. Background technique [0002] In recent years, with the rapid development of the sewage treatment industry, the number of sewage treatment plants has also increased significantly. However, while the sewage is purified and treated, the malodorous gas generated by the decomposition of organic matter in the sewage is not only harmful to metal materials, equipment and pipelines. The corrosiveness will also have an impact on the normal life of the surrounding residents. Therefore, how to effectively control the malodorous gas produced by sewage treatment plants has become a serious problem faced by the sewage treatment industry. [0003] 1 Sources, components and hazards of malodorous gases [0004] The malodorous gas in the sewage treatment plant mainly comes from the sewage and sludge ...
