摘　　要：采用培养驯化的污泥菌种,对1#陶粒、2#陶粒、塑料小球和沸石4种填料进行生物挂膜,通过对比筛选,选择性能优越的1#陶粒作为滴滤塔填料净化苯乙烯废气,结果表明,在进气量Q=0.6 m3/h,循环喷液量L=90 L/min,进气负荷小于180 g/(m3.h),去除负荷可达到163 g/(m3.h),苯乙烯净化效率达到90%以上。In this paper , 1^# ceramic pellets, 2^# ceramic pellets, plastic balls and zeolites were used as the filter media of the biological purifying system. The result showed that 1^# ceramic pellets was the best filter media of the biological purifying system to purify styrene waste gas than the others. When the gas flow was 0.6 m^3/h,the liquid flow was 90 L/min and the influx gas load was below 180 g/m^3· h, the elimination load could reach at 163 g/m3 · h and the styrene removal efficiency was above 90%.
