【摘要】：伴随着国家供给侧改革政策的进一步实施,经济转型发展刻不容缓,水资源短缺的问题进一步凸显。水资源短缺问题不仅仅关系到经济发展,更关系到社会民生、科技教育、健康生活等方面。自20世纪80年代至今,我国中水回用已经有近40年的历史,国内部分住宅小区、高校、大型宾馆已经采用中水回用系统,从而节约用水成本,减少废水的排放。但是,并没有学者针对中水回用过程中的方案分配、综合评价、费用效益分析进行全面研究。本研究通过对徐州市三种典型建筑小区中水回用方案进行模型研究,并分别进行费用效益分析,从而得出最优的中水回用用分配方案,为徐州市中水回用政策规划提供参考,具有一定的现实意义和研究价值。论文在分析徐州市中水回用现状的基础上,分别调研徐州市XS小区、中国KY大学、徐州市HG宾馆三个典型建筑小区的中水回用情况。首先,采用层次分析法(AHP)联合灰色关联度分析法,对目标进行分层,使用层次分析法(AHP)确定了利用中水进行绿化、冲厕、景观、洗车以及费用的权重值;其次,对建筑小区的中水需求量,设施建设、运营成本分析,为确定中水利用方案奠定了数据支撑;其三,提出了建筑小区中水回用配置方案,并采用灰色关联度对方案进行了综合评估;最后,采用净现值法,评价使用期限内的三种建筑小区中水回用工程的净现值,论证项目的可行性。结果表明,在考虑各建筑小区中水总量、中水需求量及使用中水额外增加的成本的基础上,通过灰色关联度分析法,确定在建筑设计时应当尽可能地在可以用中水的项目使用中水。论文的研究有助于城市中水回用政策的制定,为其它城市建筑物中水回用工程的综合效益评价研究提供参考。
[Abstract]:With the further implementation of the national supply-side reform policy, the development of economic transformation is urgent, and the problem of water shortage is highlighted. Water shortage is not only related to economic development, but also to people's livelihood, science and technology education, healthy life and so on. Since 1980s, reclaimed water reuse has been used for nearly 40 years in China. Some residential areas, universities and large hotels in China have adopted reclaimed water reuse system, thus saving water cost and reducing the discharge of wastewater. However, there is no comprehensive research on project allocation, comprehensive evaluation and cost-benefit analysis in the process of reclaimed water reuse. Based on the model study of water reuse schemes in three typical building districts in Xuzhou City, and cost benefit analysis, the optimal reclaimed water reuse allocation scheme is obtained, which provides a reference for the policy planning of reclaimed water reuse in Xuzhou City. It has certain practical significance and research value. On the basis of analyzing the current situation of reclaimed water reuse in Xuzhou City, the paper investigates the reclaimed water reuse in XS district of Xuzhou City, KY University of China and HG Hotel of Xuzhou City respectively. First, using AHP / AHP combined with grey correlation analysis to stratify the target, and using AHP to determine the weight of reclaimed water for greening, flushing, landscape, car washing and expenses; secondly, using the Analytic hierarchy process (AHP) to determine the weight of the use of reclaimed water for greening, flushing, landscape, car washing and expenses. The analysis of the reclaimed water demand, facility construction and operation cost of the construction district lays a data support for the determination of the reclaimed water utilization plan. Thirdly, the paper puts forward the water reuse allocation scheme in the construction district. Finally, the net present value (NPV) method is used to evaluate the NPV of water reuse projects in three kinds of residential areas in order to prove the feasibility of the project. The results show that, on the basis of considering the total amount of water in each building district, the demand of reclaimed water and the extra cost of using it, the grey correlation analysis method is adopted. Make sure that water should be used as much as possible in projects where water is available in the design of the building. The research in this paper is helpful to the formulation of urban water reuse policy and provides a reference for the comprehensive benefit evaluation of water reuse projects in other urban buildings.
