To remove effectively order component ($NH_3;and;H_2S$) from pig house, biofilter was made of composted pine tree bark and polite and odor removal efficiency was evaluated in the lab and pilot scales. The columns were designed with ${Phi}120mm{ imes}450mm$ (H) and ${Phi}850mm{ imes}900mm$ (H) in the size in the lab and pilot scale testes, respectively. Single material of composted pine tree bark and polite and the mixture of two materials with 7:3 ratios (vol/vol) were packed in the column, and, herein air flow was controlled upward direction from column bottom. To enhance the efficiency of biofilter, ammonia (Rhodococcus equi A3) and hydrogen sulfide oxidizing bacteria (Alcaligenes sp. S5-5.2) were inoculated in packing materials before the test Removal effect of ammonia and hydrogen sulfide gases were higher in the mixture$[88.7{sim}98.2%,;89.5{sim}97.9%]$ than that in single packing material (composted pine tree haft$[89.4{sim}98.7%,;78.7{sim}85.6%]$ and petite$[65.3{sim}73.2%,;88.7{sim}98.2%]$ by the lab scale biofilter. In the modeled pig house, about 96 and 91% of ammonia and hydrogen sulfide gases were removed by the pilot scale of biofilter, respectively. Conclusively, composted pine tree bark and polite could be a good candidate of biofilter packing materials to remove the odor components.
