摘　　要：针对生物脱臭处理工艺存在的问题，在实验室用化学方法产生H2S气体，利用筛选、驯化的高效除臭菌形成的固定化生物滤料进行连续脱臭试验．结果表明：当H2S进气量在0．05～0．5m^3／h，进气质量浓度在300～700mg／m^3时，反应器对H2S的去除率均在98％以上．反应器运行时pH值的下降并不影响H2S的去除效果．反应器启动快并能够保证足够的反应时间，具有较高的除臭效率．The removal experiment of odor containing hydrogen sulfide （ H2S） in lab was carried out continuously in high - efficient biological deodorization reactor packed with ceramics on which screened and cultivated bacterium were immobilized. Removal efficiency can reach above 98% under following conditions： the concentration of inlet between 300 mg/m^3and 700 mg/m^3 , the gas flow between 0.05 m^3/h and 0.5m^3/h. The decrease of pH did not affect the removing efficiency of hydrogen sulfide. The retention time of the reactor is long enough to treat odor efficiently.
