| 摘 要： | 应用生物滴滤塔进行了二氯甲烷和1,2-二氯乙烷混合废气净化的研究,使用制药厂活性污泥挂膜,35 d后挂膜完成,对二者的去除率可分别维持在80%和75%以上.对二氯甲烷和1,2-二氯乙烷的最大去除负荷分别为13 g·(m3·h)-1和10g·(m3·h)-1.CO2的产生负荷与混合废气的去除负荷呈线性关系,生物滴滤塔对混合废气的矿化率维持在61.2%.对混合废气中二氯甲烷和二氯乙烷相互作用考察发现两者存在一定的抑制作用,同时考察了反应器运行过程中生物量的变化情况.

| Abstract: | An experimental investigation on purification of waste gas contaminated with a mixture of dichloromethane(DCM) and dichloroethane(1,2-DCA) was conducted in a biotrickling filter (BTF) inoculated with activated sludge of pharmaceuticals industry. Stable removal efficiency(RE) above 80% for DCM and above 75% for 1,2-DCA were achieved after 35 days, indicating that biofilm was developed. The best elimination capacity (EC) of DCM and 1,2-DCA were 13 g ·(m3 ·h)-1 and 10 g ·(m3 ·h)-1 respectively. And there was a linear relationship between the production of CO2 and mixed gas EC, the maximum mineralization rate of mixed gas stabled at 61.2%. The interaction test indicated that DCM and 1,2-DCA would inhibit with each other. The changing of biomass of BTF during the operation process was also been studied. |
