结合某冶炼厂的生产实际,采用层次分析法,运用Excel进行权重求解和一次性分析,确定铜冶炼行业清洁生产评价指标体系以及每个评价指标的权重.结果表明,铜精矿耗量指标的权重值高于其他指标的权重值,废水与废气指标的权重值也高于其他同类指标.通过建立清洁生产评价指标体系,对企业进行全过程综合评价,评定企业的清洁生产水平.通过对各项指标的实际达到值、评价基准值和指标的权重值进行计算和评分,综合考评企业实施清洁生产的状况和企业清洁生产程度.
Combined with the actual production of a smelter, using analytic hierarchy process, the use of Excel weight solution and one-time analysis to determine the copper smelting industry cleaner production evaluation index system and the weight of each evaluation index.The results show that copper concentrate consumption index The weight value is higher than the weight value of the other indicators, the weight value of the waste water and the exhaust gas index is also higher than other similar indicators.By setting up the index system of cleaner production evaluation, the whole process of the comprehensive evaluation of enterprises to assess the level of cleaner production.According to each The actual value of the index, the benchmark value and the index weight value calculation and grading, a comprehensive assessment of the implementation of cleaner production enterprises and the level of cleaner production.
