电解铝清洁生产审核中高费方案可行性评价研究

Study on Scheme Feasibility Assessment of Cleaner Production Audit in Aluminum Electrolytic Industry

针对电解铝企业"能耗高、污染重"的特点,以"节能、减耗、减污、增效"为主旨,结合层次分析-模糊判断(AHPFuzzy)综合评价法,构建了电解铝企业清洁生产方案评价指标体系和综合评价模型,探索AHP-Fuzzy模型在电解铝企业清洁生产审核中高费方案可行性分析中应用的可行性。结果表明,AHP-Fuzzy综合评价法可以成功地应用于电解铝企业清洁生产中高费方案的筛选,筛选出的方案实施后取得了良好的环境效益、经济效益和社会效益。

According to the characteristics of ＂high energy consumption, heavy pollution＂of aluminum electrolytic industry, with＂energy saving, consumption reducing, pollution decreasing and benefit increasing＂as the dominant purpose, the evaluation index system for cleaner production scheme in aluminum electrolytic industry was constructed by combing with AHP-Fuzzy comprehensive evaluation method, and the feasibility of the comprehensive evaluation model to be used in the evaluation of cleaner production scheme in this industry was explored.It shows that AHP-FUZZY comprehensive evaluation method can be successfully applied in screening cleaner production high-and middle-cost schemes in aluminum electrolytic industry, and the good economic, social and environmental benefits could be realized by implementation of the schemes screened out.
