中文摘要:
      中国是典型的缺水国,水资源供需矛盾已经成为制约中国经济发展的关键因素。为进一步缓解城市水资源匮乏的社会问题,城市回用水的发展越来越受到人们的重视。首先从水质的角度,将中水、雨水与饮用水进行比较,再结合其作为城市杂用水、农业灌溉水、工业冷却水等水资源利用形式的不同水质要求,探讨了中水和雨水这类低水质非常规用水的回用可行性;再从水量的角度,通过计算城市可替代回用水量(Qt)、可回用中水量(Qz)和可回用雨水量(Qy),以及实际回用雨水量(Qy1)、实际回用中水量(Qz1)和实际回收水量(Qavail1),分析了中国几个典型缺水城市回用水在城市用水中的供需关系。结果表明:城市中水和雨水等回用水对城市各类非接触用水有着非常好的替代作用,目前城市对回用水的需求量远高于回用水供应量,有着很大的发展空间。最后分析中水和雨水的利用前景及城市用水趋势,结合现阶段城市雨污水收集发展现状,提出对应的雨污水资源化、经济化的发展需求。
英文摘要:
      China is a typical country with water shortage, and the contradiction between water supply and demand has become a key factor restricting its economic development. In order to further alleviate the social problem of urban water shortage, the development of urban water reuse has been paid more and more attention. First, the reuse feasibility of low quality water such as reclaimed water and rainwater were discussed from the perspective of water quality, by comparing with drinking water, and combining with different water quality requirements of water resource utilization forms such as urban miscellaneous water, agricultural irrigation water and industrial cooling water. Second, from the perspective of water quantity, by calculating the Alternative Recycling Water(Qt), available reclaimed rainwater(Qy), available reclaimed sewage(Qz), real reclaimed rainwater(Qy1), real reclaimed sewage (Qz1) and real reclaimed water(Qavail1), we analyzed the supply and demand relationship of reuse water in urban water consumption in several typical water-shortage cities in China. The results showed that urban reclaimed sewage-water and rainwater have a very good substitution effect on all kinds of non-contact water in the city. At present, the urban demand for reclaimed water is much higher than the supply of reclaimed water, and there is a great room for development. Finally, the utilization prospect and trend of urban water use of reclaimed sewage-water and rainwater are analyzed, and the development demand of rainwater-sewage resources and economy is put forward based on the current development status of urban rainwater-sewage collection.
