摘　　要：[Objective] To find out the process conditions and influence factors for the biotreatment of odor gases of hydrogen sulfide（H2S） and ammonia（NH3）. [Method]The degradation performances on H2 S and NH3 were investigated during the start-up and stable operation process of biofilter with ceramsites as the packing microorganisms. [Result] The biofilm formation of the biofilter system to purify the waste gas of H2 S was completed within 9 d, and the removal rate of H2 S could reach up to 99% with the initial concentration of 100-1 000 mg/m^3 and empty bed residence time（EBRT） of142-290 s. The biofilm formation of the biofilter system to purify the waste gas of NH3 was completed within 10 d with the removal rate reaching up to 94.61%.[Conclusion] Under suitable conditions, the biofilter showed high removal rates to both H2 S and NH3.[目的]探讨净化单一恶臭气体H2S和NH_3工艺条件及影响因素。[方法]以陶粒作为生物滴滤塔的填料负载微生物,考察了生物滴滤塔于挂膜启动及稳定运行阶段对H_2S和NH_3的降解性能。[结果](1)净化H_2S废气的生物滴滤塔系统在9 d内即完成挂膜,在进口浓度100-1 000 mg/m^3,空床停留时间(EBRT)142-290 s的条件下,H_2S的去除率均可达到99%以上;(2)净化NH_3废气的生物滴滤塔在10 d内即完成挂膜,对NH_3去除率均达到94.61%。[结论]适宜条件下,生物滴滤塔对于H_2S和NH_3的去除率均较高。
