Problems solved by technology

Natural organic fillers have the advantages of being cheap, easy for microorganisms to attach and grow, and rich in organic nutrients. The disadvantages are perishable, poor mechanical properties, and problems such as filler layer collapse and compaction are prone to occur after long-term use.
Inert inorganic fillers are easy to obtain, strong, and stable in chemical properties, which may easily lead to problems such as low biological activity, long reactor start-up time, and increased operating costs.

Abstract

The invention provides a deodorizing filler and a preparation method thereof, a deodorizing device, a deodorizing method, and application, belonging to the technical field of deodorization. The deodorizing filler includes a main filler body and a microbial agent. Based on the mass percentage of the main filler body, the main filler body includes 35 to 45% of fly ash, 20 to 30% of clay, 10 to 20% of dewatered sludge, 5% to 15% organic minerals and 5% to 15% of a binder. The microbial agent includes Thiobacillus, saccharomycete, Bacillus subtilis, Pseudomonas putida and nitrifying bacteria. Thedeodorizing filler has high deodorizing efficiency and can effectively reduce malodorous substances in gas.

Description

technical field [0001] The invention relates to the technical field of deodorization, in particular to a deodorization filler, a preparation method thereof, a deodorization device, a deodorization method and an application thereof. Background technique [0002] Urban landfills, municipal sewage treatment plants and other odor-producing enterprises are usually built in the suburbs, but with the development of the city, the distance between these factories and residential areas continues to decrease, and odor and other air pollutants have become an urgent need. solved problem. Unpleasant odors will be generated and emitted during wastewater treatment, which will endanger the health of surrounding residents and have a negative impact on community life. Due to the impact of air on the atmospheric environment, the collection and treatment of odor from sewage treatment plants has become an urgent task. The original deodorization technology of the sewage plant is difficult to mee...
