AI Technical Summary

Technical Problem

There is a lack of effective microbial deodorizers for space deodorization in the current technology, especially for removing irritating odors such as ammonia and hydrogen sulfide produced during the breeding process, and existing methods are not suitable for space applications.

Method used

A compound microbial agent, including Bacillus cladei, Bacillus stolonifera, Bacillus stolonifera, Bacillus horikoshi, Bacillus megaterium, Bacillus licheniformis, Bacillus cereus, and Bacillus spheroidis, is used. It is sprayed directly into the odor-polluted space through a spraying device, and the metabolic activities of these strains are used to eliminate the odor.

Benefits of technology

It achieves rapid and efficient deodorization of breeding sheds and large-scale farms, with an ammonia degradation rate of up to 95% and a hydrogen sulfide degradation efficiency of up to 90%. There are no new sources of pollution after deodorization, and the effect lasts for 6-120 hours.
