燃煤电厂清洁生产评价方法比较研究.pdfVIP

摘 要 煤电行业是我国国民经济和社会发展的基础，但同时也是能源转换行业污染物排放的 大户。在燃煤电厂行业推行清洁生产势在必行。清洁生产评价能够有效评估企业开展清洁 生产的程度，明确企业与先进水平之间所存在的差距和问题。目前评价方法多种多样，但 是评价效果良莠不齐，寻求一种科学合理的评价方法对促进燃煤电厂清洁生产的有效开展 有着重要意义。 论文介绍了清洁生产评价方法的基本理论，对现有的评价方法进行对比分析。运用常 用的综合指数法、平均指数法和模糊综合法分别进行评价对比。以阜新电厂为试点企业， 通过到企业进行实地调研和资料收集，构建了 5 个方面共 19 个指标的评价体系。用超标 权重方法对指标赋予权重，用梯形分布确定隶属度函数。由评价结果的分析可知，三种方 法所得出的评价结果相同，但是模糊综合评价法不但能够评价出企业整体的清洁生产水平 程度，还能够找出薄弱环节，挖掘企业的清洁生产潜力。体现出不同影响因素对企业整体 水平的贡献不同，使指标能够有机的联系起来，综合客观的反映出企业的清洁生产水平。 对阜新电厂的试点研究，评价结果与企业的实际情况基本符合，对于燃煤电厂行业中其它 企业的清洁生产水平评价具有一定的参考作用。 关键词：燃煤电厂；清洁生产评价；评价模型；模糊综合评价 - I - Abstract China’s coal-fired industry isn’t the only basis for the national economy and social development, but is an emitter of pollutants in energy conversion industry. Therefore in the industry it is imperative to carry out cleaner production method, CPA can effectively assess the level that an enterprise achieve so that the gap is seen between the enterprise and other enterprises with advanced level. At present, although there are kinds of assessment methods, evaluation result is uneven. Therefore a scientific and reasonable assessment method has to be found, which plays an important role in effective development of cleaner production in coal-fired power plant. The paper introduces the basic theory of clean production evaluation method, which compares with assessment method available. Composite index method, average index method and fuzzy synthetic evaluation method most commonly used to be assessed and compared with others respectively. After fieldwork and data collection in Fuxin Power Plant that is as a pilot enterprise, constituting 5 areas 16 indicators in the evaluation system. Wi
