摘　　要：介绍了生物膜法净化低浓度CS2 、H2 S含硫废气的基本原理 ,采用生物膜填料塔进行了净化低浓度CS2 废气的实验研究 .结果表明 :生物膜填料塔在最佳操作条件 (进口气体浓度 1 0 0mg/m3、气体流量 0 .1m3/h、循环液流量 2 0L/h、pH =4.0 )操作时 ,对CS2 去除率可达到 80 % .表明生物膜填料塔净化低浓度的CS2The basic principle of using biological method about purification of CS 2 waste gas containing sulpho-compound is introduced and an approach to purification of CS 2 waste gas in low concentration by using a biological trickling filter is studied. The results of preliminary experiment show that when the bio-filter is operated at the optimum operation conditions (the concentration of CS 2 in influent gas is 100?mg/m 3, the gas flow is 0.1?m 3/h, circulated liquid flow is 20?L/h and pH is 4.0), the removal efficiency of CS 2 can reach 80%. It indicates that biological trickling filters can be used to bio-purify CS 2 waste gas.
