基于多方法优化的行业优控污染物清单筛选技术研究及应用

Research and application of screening technology of industrial priority control pollutants list based on multi-method optimization

针对优控污染物筛选技术缺乏行业层面的研究以及筛选技术不完善的问题,基于清洁生产全过程管控理念,在以往对于行业优控污染物清单筛选技术研究基础上,将综合评价法、Hasse图解法和层次分析法综合起来进行分析评价,形成一种矢量分析与标量分析相结合的综合筛选技术。并将该筛选技术在常州市印刷电路板(PCB)行业开展应用。结果表明:经过全流程调查和气相色谱-质谱联用仪90%匹配度下的水样检测分析结果,得到常州市PCB行业特征污染物清单中共含172种物质;PCB行业优控污染物清单中共含有30种物质,包括卤代烃3种、苯系物9种、酯类3种、醛类1种、醇类5种、酮类2种、金属离子5种、盐类1种、其他1种。提出的综合筛选技术可作为行业优控污染物筛选方法,能够更加科学有效地得出常州市PCB行业优控污染物清单。

In order to solve the problems of the lacking of industry-level research and imperfect screening technology for priority control pollutants,the comprehensive evaluation method,Hasse diagram method and analytic hierarchy process were integrated to form a comprehensive screening technology combining vector analysis and scalar analysis,according to the concepts of cleaner production and whole-process control,and based on the previous researches on the screening technology of the industrial priority control pollutants list.Then,the screening technology was applied in the printed circuit board(PCB)industry in Changzhou City.The results showed that after the whole process investigation and analysis of water samples by gas chromatography-mass spectrometry with 90%matching degree,the list of characteristic pollutants in PCB industry contained 172 substances.There were 30 kinds of substances in the list of priority control pollutants in PCB industry,including 3 kinds of halogenated hydrocarbons,9 kinds of benzene series,3 kinds of esters,1 kind of aldehydes,5 kinds of alcohols,2 kinds of ketones,5 kinds of metal ions,1 kinds of salts and 1 kind of others.The proposed comprehensive screening technology could be used for the industry so as to obtain the list of pollutants under priority control in PCB industry in the city more scientifically and effectively.
