【摘要】：近些年来,由于经济的高速发展,人们物质生活水平的提高,导致目前资源消耗过快,同时,民众又没有形成高度的节约以及环保意识,所以造成目前生态环境质量急速下降的局面。尤其是在水资源的利用上,水资源属于人类生活以及生产必不可少的资源。而由于过度使用以及废水随意排放,已经造成了严重的水资源污染问题。我国乃至世界上一些国家和组织都可以制定相关政策,或采取类似的措施来解决环境污染,生态平衡的问题,制约这种随意排放,只顾经济利益忽视环境保护的情况。尤其是对于水资源的保护上,地位尤其重要。水资源是人类赖以生存和发展的战略资源。目前水资源污染主要是由于生活污水和工业污水的随意排放。尤其是工业污水,其成分复杂,污染物繁多,如果不能严格按照规定来进行废水的处理而直接排放的话,会对周边的地下水源,湿地等造成污染。国务院在近些年制定了相关的政策,来制约工业废水的排放问题。如果不能达到相关的标准,相关企业和工厂将会面临关停的风险。在这种政策背景和社会背景下,西柏坡电厂进行了废水排放改造项目,以期达到废水的安全清洁排放,尽量达到不污染周围水源的目的。基于以上的研究意义,本文首先对西柏坡电厂的改造工程进行了描述,以便于为后文的综合评价提供基础。主要对其工程方案进行了介绍,包括循环水排污水处理系统改造方案、酸碱再生废水回用改造方案、高含盐废水减量处理系统改造方案以及工业废水处理系统改造方案。然后在阅读了大量相关评价论文的基础上,针对该工程项目选取合适的评价方法,及组合评价的方法,首先选取指标,从社会、环境以及经济角度选取不同的指标进行表述,在利用层次分析法对指标进行权重的计算。最终利用模糊综合评价的方法对该改造项目进行评价。最终得出结论。该项目符合国家技术政策及行业发展规划,电厂可获得良好的社会效益和环保效益,具有重要的现实意义和借鉴意义。
[Abstract]:In recent years, due to the rapid development of the economy and the improvement of people's material living standards, the current consumption of resources is too fast, and at the same time, the people have not formed a high degree of conservation and environmental awareness. Therefore causes the present ecological environment quality to drop rapidly the situation. Especially in the use of water resources, water resources belong to human life and production of essential resources. Due to overuse and arbitrary discharge of wastewater, serious water pollution has been caused. Some countries and organizations in our country and in the world can make relevant policies or take similar measures to solve the problem of environmental pollution and ecological balance, restrict this kind of arbitrary discharge, and ignore the environmental protection only in economic interests. Especially for the protection of water resources, the position is particularly important. Water resources are strategic resources for human survival and development. At present, the pollution of water resources is mainly due to the random discharge of domestic sewage and industrial sewage. Especially the industrial sewage, its composition is complex, the pollutant is various, if cannot carry on the waste water treatment and the direct discharge strictly according to the stipulation, will cause the pollution to the surrounding underground water source, the wetland and so on. The State Council has formulated policies in recent years to limit the discharge of industrial wastewater. If the relevant standards are not met, the relevant enterprises and factories will face the risk of closure. Under this policy background and social background, Xibaipo Power Plant carried out the project of wastewater discharge transformation, in order to achieve the safe and clean discharge of wastewater, and to achieve the goal of not polluting the surrounding water source as far as possible. Based on the above research significance, this paper first describes the reconstruction project of Xibaipo Power Plant, so as to provide a basis for the comprehensive evaluation. This paper mainly introduces its engineering scheme, including the revamping scheme of circulating water drainage wastewater treatment system, the reusing of acid and alkali regenerated wastewater, the retrofitting scheme of reducing treatment system of high salt wastewater and the reforming scheme of industrial wastewater treatment system. Then, on the basis of reading a large number of related evaluation papers, select appropriate evaluation methods and combination evaluation methods for the project, first select indicators, select different indicators from the social, environmental and economic angles to express. AHP is used to calculate the weight of the index. Finally, fuzzy comprehensive evaluation method is used to evaluate the reconstruction project. The final conclusion is drawn. The project is in line with the national technical policy and industry development plan, and the power plant can obtain good social and environmental benefits, which has important practical significance and reference significance.
