摘　　要：文章分析了各行业VOCs治理技术应用现状及环境治理成本情况,针对青岛市橡胶和塑料制品业、金属制品业、化学原料和化学制品制造业、汽车制造业等8个重点行业开展了VOCs治理现状进行调查研究。结果表明:青岛市橡胶和塑料制品业、金属制品业在企业数量及VOCs排放量均占优势,属本地特色行业;化学原料和化学制品制造业、汽车制造业虽然企业数量较少但VOCs排放量占比较高。青岛市目前应用最多的治理技术为光解/光催化,主要应用于橡胶和塑料制品业;冷凝、生物降解技术对废气成分及处理条件有一定要求,导致应用相对受限;RTO、RCO技术运行稳定且处理效率高,但治理成本也较高。青岛市应加快推进低挥发性有机物含量原辅料和产品替代工作,从源头削减VOCs排放,同时建设区域共享喷涂中心、注塑中心等,集中采用RCO、RTO设备进行废气处理,缓解部分企业单独处理高浓度、低排放量、非连续的有机废气而导致的经济压力。The current situation of VOCs treatment technology application and environmental treatment costs for various industries in Qingdao are investigated,including rubber and plastic products,metal products,chemical raw materials and chemical products manufacturing,automobile manufacturing,etc.The results show that the rubber and plastic products industry and metal products industry in Qingdao are dominant in the number of enterprises and VOCs emissions,which are local characteristic industries.Although the number of enterprises in chemical raw material and chemical product manufacturing and automobile manufacturing is small,the proportion of VOCs emissions is relatively high.At present,the most widely used treatment technology is photolysis/photocatalysis,which is mainly used in the rubber and plastic products industry.Condensation and biodegradation technologies have certain requirements on exhaust gas components and treatment conditions with a limited applicability.RTO and RCO are operated stably and both of them have a high processing efficiency.However,the cost of governance is high.It is recommended to accelerate the replacement of raw materials with low volatile organic contents,and reduce VOCs emissions from the source.In addition,regional shared spraying centers and injection molding centers using RCO and RTO equipment for waste gas treatment,should be built to alleviate the economic pressure for some enterprises dealing with high-concentration,low-emission,and discontinuous organic waste gas alone.
