摘　　要：以广东省佛山市某塑料生产企业排放的有机废气为的治理目标,采用除尘除油预处理+"等离子-生物过滤"的联合处理工艺,以探究高效经济的塑料有机废气处理技术。全组分分析结果显示该厂废气中主要污染物为苯系物,其占TVOCs比例超过80%;特征污染物为苯乙烯、甲苯、乙苯。根据该厂废气成分及其浓度特征,对处理工艺进行了工程效果评价及经济性评价。结果表明,稳定运行75 d后,联合工艺对该厂废气中TVOCs的去除率可达95.3%,其中等离子和生物滤池工艺段的TVOCs去除率分别为36.57%和92.60%,总体上实现了对该厂废气的高效净化。该工程案例可为塑料有机废气的生物处理提供参考。Aiming at the organic waste gas treatment in the plastics industry,a case of a plastic waste gas treatment demonstration project in Foshan City,Guangdong Province was investigated.Through the full elemental analysis,it was found that the main pollutants of the plastic waste gas of the plastics industry were BTEX compounds,accounting for more than 80%of TVOCs.The characteristic pollutants were styrene,toluene,and ethyl benzene.According to the composition and concentration characteristics of the plastic waste gas,a“plasma-biofiltration”combined treatment process was designed.After a 75 d stable operation,the combined process achieved a TVOCs removal rate of 95.3%.The TVOCs removal rates of the plasma and biological filter process sections were 36.57%and 92.60%,respectively.Overall,the waste gas was efficiently cleaned and this case study could provide reference basis for plastic waste gas treatment.
