摘　　要：通过构建锌冶炼行业水污染控制技术评价指标体系,结合层次分析-模糊综合评价(AHP-FCE)法,分别对污酸及酸性废水、综合废水2类废水建立锌冶炼行业水污染控制技术评价标准,对2类废水的8种污染控制技术进行综合量化评价。结果表明:基于选择性吸附—气液强化硫化—蒸发浓缩—氟氯分离的污酸资源化处理关键技术综合评价得分为4.38,为评价的4种污酸及酸性废水污染控制技术中最优的;基于重金属废水生物制剂深度处理技术的重金属冶炼废水生物-物化组合处理与回用技术综合评价得分为4.14,为评价的4种综合废水处理与回用技术中最优的。该评价结果可为企业选择适宜水污染控制技术提供可靠依据,也可为管理部门推荐最佳可行性技术及制订相关政策标准提供强有力的支撑。The evaluation index system of water pollution control technology of zinc smelting industry was constructed,the analytic hierarchy process-fuzzy comprehensive evaluation(AHP-FCE)model was developed,and the evaluation standards of water pollution control technology of zinc smelting industry were established in two technical units:the complete set of pollution control technology for waste acid and acid wastewater and the complete set of comprehensive wastewater treatment and reuse technology.Then the comprehensive quantitative evaluation of eight pollution control technologies in two technical units was carried out based on AHP-FCE.The results showed that:The comprehensive evaluation score of the key technology of waste acid resource treatment based on“selective adsorption-gas-liquid enhanced sulphidation-evaporation concentration-fluorine chlorine separation”was 4.38,which was the best of the four waste acid and acid wastewater pollution control technologies;the comprehensive evaluation score of the heavy metal smelting wastewater biophysical and chemical combination treatment and reuse technology based on“biological agent advanced treatment technology of heavy metal wastewater”was 4.14,which was the best of the four comprehensive wastewater treatment technologies.The evaluation results couldprovide a reliable basis for enterprises to choose suitable water pollution control technology,and also provide a strong support for the management department to recommend the best feasible technology and formulate relevant policies and standards.
