摘要
基于模糊层次分析法(FAHP),从国内现有泄漏检测与修复(LDAR)相关标准和技术指南中筛选出项目建立、现场检测、泄漏修复与复测、台账管理4个层面14项评估指标,构建LDAR实施效果评估的层次结构模型,通过对专家、企业、第三方服务商3类群体代表发放30余份问卷调查,进而计算指标权重,以解决国家日益重视挥发性有机物(VOCs)管控形势下,如何科学评估LDAR实施质量的难题。结果显示,LDAR实施效果评估中一级指标排序依次为泄漏修复与复测(0.305)、项目建立(0.281)、现场检测(0.245)和台账管理(0.169),14项二级指标权重排序中泄漏修复及时性权重最高、免予检测合规性权重最低。研究在权重值的基础上建立一套系统的LDAR实施效果评估体系,并将其应用于制药、塑料制品、合成树脂、涂料油墨制造的10家企业,得出制药行业整体实施效果偏好,合成树脂与涂料油墨行业实施水平相当,塑料制品企业在落实LDAR工作的合规性略低。
Based on the fuzzy analytic hierarchy process(FAHP),14 evaluation indicators in four levels,including project establishment,on-site inspection,leak repair and retesting,and account management,were selected from the existing LDAR-related standards and technical guidelines in China,and a hierarchical structure model for LDAR implementation effect evaluation was constructed.By distributing more than 30 questionnaires to representatives of3 types of groups:experts,enterprises,and third-party service providers,and then calculating the index weights,in order to solve the problem of how to scientifically assess the quality of LDAR implementation under the situation that the country pays more attention to the control of volatile organic compounds(VOCs).The results showed that the primary indicators in the assessment of LDAR implementation effectiveness were leak repair and retesting(0.305),project establishment(0.281),site inspection(0.245)and account management(0.169),and the 14secondary indicators were ranked with the highest weight of leak repair timeliness and the lowest weight of compliance with exemption from inspection.The study established a systematic LDAR implementation effect assessment system based on the weight values and applied it to 10 enterprises in pharmaceutical,plastic products,synthetic resin and coating ink manufacturing,and concluded that the overall implementation effect of the pharmaceutical industry is preferred,the synthetic resin and coating ink industries have comparable implementation levels,and the compliance of plastic products enterprises in implementing LDAR work is slightly lower.
