摘　　要：对生物滴滤法处理低浓度H2S恶臭气体进行了研究，考察并分析了喷淋水量、pH值、停留时间对H2S去除率的影响．结果表明：当进气浓度小于30mg／m^3时，循环液pH值在0．5-2．0之间、喷淋水量为10L／h、气体停留时间为30s左右的条件下，H2S的去除率可以达到100％．The method of biotrickling filter for treating low concentration hydrogen sulfide gas is investigated. The effects of amount of spray water, pH value and retention time on the H2S removal rate are discussed. The results show that when the inlet hydrogen sulfide concentration is lower than 30 mg/m^3, the pH value is between 0.5 and 2.0, the amount of spray water is 10 L/h and the gas retention time is about 30 s, the removal rate of H2S is 100%.
