Biologically deodorizing method

The invention relates to a biological deodorization. It has solved the difficulty of biological method only being able to remove low degree odor with simple way. It goes like this: domesticating, inoculation, purification, enriched medium, hybrid to grow the deodorization biological sperm, then prepare fixed biochemical stuff, with the odor being filtered and deordorized. The feeding cycle for nutrient solution is 12h, inlet air flow is 0. 012-0. 1m3/h, average air density being 0-800mg/m3, volume charge of H2S being 0-124. 8mgs/kg active carbon . h, volume charge of alkaline being 0-110mgN/kg active carbon . h, temperature controlled within 20-30deg.C, air hanging period within 20-150s. It has high efficiency in deodorization, simple in equipment and economical in running expenses.
