Experimental study on biological removal of malodorous gas containing hydrogen sulfide

Biomass power generation is the next essential part of green power generation, and in the future its proportion of the power industry will be bigger and bigger. Concomitant with the biomass power generation is producing a large amount of mainly hydrogen sulfide gas. Selecting hydrogen sulfide as a research object which is the main odor pollutant, the management of odor gas hydrogen sulfide was investigated by using the combined process Bio-Trickling reactor in this paper. Meanwhile, diverse factors which might influence the operation of bio-trickling reactor were inspected and the reacting mechanism of biological deodorization was analyzed as well. Technical route in this paper would provide new methods and thinking for management of pollution composed of multicomponent gases which is represented for odor waste gas. Similarly, research conclusions would offer basic data and reference for further application study.
