摘要
通过对区域内特定行业企业进行调研,开展挥发性有机物(VOCs)采样分析,并对VOCs排放特征及健康效益进行评价.结果显示,粉体涂料喷涂主要污染物为烷烃(85.8％),UV漆喷涂主要污染物含氧VOC(91.4％),PU漆涂主要污染物为含氧VOC(72.4％)和烷烃(22.4％).粉体涂料喷涂能够显著降低排放VOCs的臭氧生成潜势(OFP),粉体材料替代对环境存在一定的正面效益;在健康方面,喷粉车间可能存在致癌风险,UV漆泵房和PU漆泵房均存在一定的致癌风险,粉体材料替代UV漆和PU漆对环境存在一定的正面效益具有非致癌健康风险的正面健康效益;企业存在无组织排放较大,末端治理设施处理效率较低等情况,需加强对VOCs的收集与处理管控.
Abstract
Through the investigation of enterprises in specific industries in the region,volatile organic compounds(VOCs)sampling analysis was carried out,and the emission characteristics and health benefits of VOCs were evaluated.The results showed that the main pollutants were alkane(85.8％)in powder coating,oxygen-containing VOC(91.4％)in UV coat-ing,and oxygen-containing VOC(72.4％)and alkane(22.4％)in PU coating.Powder coating can significantly reduce the ozone generation potential(OFP)of VOCs emission,and powder material substitution has some positive environmental benefits.In terms of health,the dusting workshop may have carcinogenic risks,and the UV paint pump room and PU paint pump room have certain carcinogenic risks.The replacement of UV paint and PU paint by powder materials has certain pos-itive environmental benefits and positive health benefits that are non-carcinogenic health risks.Enterprises have large unor-ganized emissions and low treatment efficiency of end treatment facilities,so it is necessary to strengthen the collection and treatment control of VOCs.
