【摘要】：随着经济社会的快速发展,全社会对水资源的需求量日益增加,水资源成为制约社会发展的主要因素之一。为解决水资源短缺的问题,多种新型水源逐渐成为常规水源的有效补充。再生水、海水淡化水、雨水、微咸水等非常规水源的利用日益广泛。随着海水淡化技术的逐步成熟,在我国沿海地区海水淡化工程的建设越来越多。海水淡化工程的落成,使得海水淡化水成为区域水资源供应的重要组成。作为非常规水源,海水淡化水由于其生产工艺的特殊性,使得淡化水较常规水源纯净度高,水质属于高品质水源。海水淡化水的用户与常规水用户存在一定用水需求差别。海水淡化水利用需要具有相应的配套设施和独特的使用模式,在常规水源持续供水多年的地区,海水淡化水的利用设备尚存在一定欠缺。本次研究首先开展海水淡化水淡化技术及淡化水水质分析。对新加坡、澳大利亚和西班牙这些利用海水淡化水较成功的国家进行海水淡化水的利用过程与方式调研,对国外海水淡化水利用情况进行总结;同时进行国内海水淡化水生产及利用情况调研,分析海水淡化水利用途径及方式;从淡化水产能、工艺方法、水质和利用途径等方面,对天津市已经建成的海水淡化水厂进行调查,对利用过程中的问题进行分析;在供水方式、供水对象、供水范围、用户需求、供水水量、供水过程、供水安全、供水价格和供水影响等方面,开展海水淡化水与常规供水的对比分析,提出两种水源各自供水特点及适应的供水方式;对天津市海水淡化水的用户进行用水潜力分析,阐明用水户的用水需求,划分淡化水的应用区域及利用领域,测算天津市海水淡化水的利用潜力;结合天津市的用水特点,提出天津市海水淡化水的建议利用模式。
[Abstract]:With the rapid development of economy and society, the demand for water resources in the whole society is increasing day by day. Water resources have become one of the main factors restricting the development of society. A number of new sources of water gradually become an effective supplement to conventional sources. Reclaimed water, seawater desalination water, Rain Water, brackish water and other unconventional water sources are increasingly widely used. With the gradual maturity of seawater desalination technology. The construction of seawater desalination project is more and more in the coastal areas of our country. With the completion of seawater desalination project, seawater desalination water becomes an important component of regional water resources supply, as an unconventional source of water. Because of the particularity of its production technology, desalination water is more pure than conventional water source. The water quality belongs to the high quality water source. There is a certain difference between the users of seawater desalination water and that of the conventional water users. The use of seawater desalination water requires corresponding facilities and unique usage mode. The equipment of seawater desalination is still lacking in the area where the conventional water supply has been supplied for many years. Firstly, the desalination technology and the desalination water quality are analyzed in this study. Australia and Spain, which have been successful in using desalination water, investigated the process and methods of seawater desalination water utilization, and summarized the situation of seawater desalination water utilization abroad. At the same time, the production and utilization of desalination water in China were investigated, and the ways and means of seawater desalination water utilization were analyzed. From the aspects of desalination aquatic energy, process method, water quality and utilization way, this paper investigates the seawater desalination water plant that has been built in Tianjin, and analyzes the problems in the process of utilization. In the aspects of water supply mode, water supply object, water supply range, user demand, water supply quantity, water supply process, water supply safety, water supply price and water supply effect, the comparative analysis of seawater desalination water and conventional water supply is carried out. The characteristics of water supply of two kinds of water sources and the suitable water supply mode are put forward. This paper analyzes the potential of seawater desalination in Tianjin, clarifies the water demand of water users, divides the application area and field of desalination water, and calculates the utilization potential of desalination water in Tianjin. According to the characteristics of water use in Tianjin, the suggested utilization mode of seawater desalination water in Tianjin is put forward.
