Abstract
Hydrogen sulfide, methanethiol, dimethyl sulfide and dimethyl disulfide are famous sulfur-containing offensive odor substances from sewage treatment facilities and night soil treatment facilities. In these facilities, deodorization methods are usually chemical absorption with NaOCl and adsorption with activated carbon, but the biological deodorization in sewage treatment facilities or night soil treatment facilities has been proved to be economical and efficient. In this mini review, the authors describe the study of the biological deodorization for sulfur-containing offensive odor and recently reported sulfur-oxidizing bacteria on hydrogen sulfide or methanethiol and so on, and their application to the biological deodorization for sulfur-containing offensive odor substances in sewage treatment facilities or night soil treatment facilities.
