摘　　要：本文通过对两种填料处理硫化氢气体的挂膜实验研究,表明挂膜方法、填料性能、温度、PH值、入口浓度等均影响挂膜效果与硫化氢去除率,并且得出陶粒挂膜启动时间比阶梯环快。This paper study the biological membrane growth rule by choosing two kinds of fillers degrade H2S, The results indicate that the method of membrane hanging, the capability of the fillers, temperature, the PH value, the entrance concentration have important effects on membrane growth and removal efficiency of H2S, and the biological membrane growth starting time on the sintered aggregate is less than that on the cascade ring.

关 键 词：H2S 生物膜 陶粒 阶梯环 效率
