【摘要】：随着我国工业化进程的不断推进,能源危机、工业污染、生态环境破坏等一系列问题不断的加剧,采取必要的手段进行控制已经成为了目前的研究方向。对污染排放问题最好的解决方案就是从源头进行控制,而不是进行目末端处理,清洁生产理论因此孕育而生。火力发电企业作为我国主要的发电方式,其主要原料为煤炭,而煤炭在燃烧过程中会产生粉尘、SO2、NOx和CO2等废弃物,影响生态环境,因此其生产过程的排放问题也受到了广泛的关注。为了缓解火力发电企业生产过程对环境造成的压力,清洁生产的应用就势在必行。在火力发电企业执行清洁生产的过程中,企业管理者希望能够直观的看到推行清洁生产的效果,从而根据清洁生产效果进行政策调整和优化,保证火力发电企业清洁生产措施能够适应企业的发展。因此对火力发电企业清洁生产状况进行综合评价具有十分重要意义。本文首先对清洁生产的研究背景以及实行的意义进行分析,并对国内外清洁生产的研究现状进行学习,详细介绍了目前国内外清洁生产研究的方向和内容。重点进行了清洁生产的理论研究,根据国内外清洁生产的发展过程,深入掌握清洁生产的主要组成内容和实现的目标,并将清洁生产与“末端治理”进行比较,突出进行清洁生产的必要性。根据火力发电企业的运行特点,建立适用于火力发电企业清洁生产综合评价的指标体系。构建火力发电企业清洁生产综合评价模型,运用层次分析法对数据进行预处理,确认各个指标体系的权重,得到最终的评价得分;将处理好的数据分为训练集和测试集,运用网格搜索算法进行最小二乘支持向量机参数优化;将优化后的评价模型进行火力发电企业清洁生产综合评价,评价结果表明该模型具有较高的评价精度,有一定的实用性。最后根据评价结果提出相应的清洁生产改进措施,为火力发电企业清洁生产顺利实行提供保障。
[Abstract]:With the development of industrialization in our country, a series of problems such as energy crisis, industrial pollution and ecological environment destruction are becoming more and more serious. It has become the current research direction to adopt necessary measures to control pollution. Thermal power plants, as the main mode of power generation in China, use coal as the main raw material. Coal will produce dust, SO2, NOx and CO2 wastes during the combustion process, which will affect the ecological environment. Therefore, the emission problems in the production process have also been widely concerned. In order to alleviate the production of thermal power plants, coal-fired power plants have produced a lot of wastes. In the process of implementing cleaner production in thermal power plants, managers hope to see the effect of implementing cleaner production intuitively, so as to adjust and optimize policies according to the effect of cleaner production, so as to ensure that the cleaner production measures of thermal power plants can be adapted. Therefore, it is of great significance to comprehensively evaluate the cleaner production status of thermal power plants. Firstly, this paper analyzes the background and significance of cleaner production, and studies the research status of cleaner production both at home and abroad, and introduces in detail the research direction and internal of cleaner production at home and abroad. Rong. Focused on the theoretical study of cleaner production. According to the development process of cleaner production at home and abroad, the main components and objectives of cleaner production were thoroughly grasped, and the necessity of cleaner production was highlighted by comparing cleaner production with "end treatment". A comprehensive evaluation index system for cleaner production of thermal power plants is established. A comprehensive evaluation model for cleaner production of thermal power plants is constructed, and the data is pre-processed by AHP to confirm the weight of each index system, and the final evaluation score is obtained. The parameters of least squares support vector machine are optimized, and the optimized evaluation model is used to evaluate the cleaner production of thermal power plants. The evaluation results show that the model has high evaluation accuracy and certain practicability. Implementation provides protection.
