基于氨氮减排的氮肥行业清洁生产技术评估方法

摘要

The current environmental technologies evaluation methods are mainly based on experts 'qualitative estimation and lack of comprehensive evaluation methods .Aiming at this problem and combined with the total ammonia discharge control requested by National Economic and Social Development Plan in 2011-2015 and the ammonia discharge reduction demand of nitrogen fertilizer industry , the index system and an integrated evaluation method for cleaner production technology evaluation based on ammonia discharge reduction was built .The weight of each index was obtained with analytic hierarchy process ( AHP ) , and the discharge reduction technologies evaluated using grey correlation analysis method .The modeling process of the mathematical model of the integrated evaluation method was provided with an application example analyzed .%针对国内环境技术评估以定性判断为主，缺乏综合评估方法的问题，结合国家“十二五”规划纲要对氨氮排放总量控制和氮肥工业氨氮减排的需求，构建了基于氨氮减排的氮肥行业清洁生产技术评估指标体系和综合评估方法。利用层次分析法确定各指标的权重，利用灰色关联度法对氨氮减排技术进行评估，同时给出了该评估方法数学模型的建模过程，并进行了实例应用分析。
