" # Keyword words : biofilter, immobilized cell, hydrogen sulfide, ammonia gas./ Hydrogen sulfide (H2S) and ammonia (NH3) is highly odorous, toxic, and colorless air pollutants. Considerable amounts of hydrogen sulfide and ammonia gas are produced in association with industrial processes, such as livestock farms, leather tannery, food processing, wastewater treatment, as well as paper and pulp manufacturing. Biotreatment has been proven. to be an affective and inexpensive method for removing air pollutants. Hence, we developed a particular degas system. First, two speccies, Psedomonas putida and Arthrobacter oxydans, isolated from pig feces acclimated with either hydrogen sulfide gas or ammonia gas or both. Then, we mixed cells with 4 % alginate solution to process immobilization. These immobilized cells were packed into two kinds of the fluidized-bed biological reactors. The reactors were supplied by different ratios of H2S/NH3 mixture gas and then were operated continuously. The results show that the H2S removal efficiency of the biofilter is significantly affected by high concentrations of H2S and NH3. The NH3 removal efficiency of the biofilter is found unaffected by high NH3 concentration, but it will be hindered by high concentration of H2S. The aim of this study is to create a biological filter with high efficiency and to establish an economic and practicable way to resolve odor emission. %&'() *+ µp¶LM.=>?"<·¸7K¹ º%»¼½¾¿%(¹Àº0Á(¸Â "M(·¸^2ÃIÄÅ<J.µ p<LM·¸Æ¤¥¦_Ç<LM]^ `:¸ÈÉ¦Z[]a0sÊ¶<ËÌ@ !"#$Í»¼Î¾¿%K¹]0 (d^Ï45"Ð<(»¼0!" °¼^!"#$r¤¥¦ 80 ÑÒ100 Ñ<Z[]a^9Ó \iÔÕÖLM· ×[1]^9_ØÙsÚÛLM@Y¢.
