水资源的缺乏使越来越多的城市和城区开始使用中水作为额外的经济合理的供水水源,并为此制定相应政策.然而.不适宜的中水利用政策往往对用水户使用再生水产生不利影响.本研究目的在于评价中水设施建设适宜性并分析不同行业的中水利用适宜情况,为制定或修订中水利用政策提供参考.本研究以北京市为研究区,在中水生产成本影响因素分析基础上,得到了中水设施建设限制因素和中水设施建设适宜条件,并对北京市机关、高校、饭店的用水户进行了适宜性评价.本研究结果表明,运行水量对中水生产成本有决定性影响.有效原水量对应的给水量、有效中水需求量、建筑面积适合作为中水设施建设影响因素,它们的下限可作为中水设施建设适宜条件.本研究通过分析北京市部分机关、高校、饭店用水户的用水情况,得到这些行业的中水设施建设适宜条件,并用于适宜性评价.评价结果表明,大部分机关用水户和大部分一、二星级饭店不适宜建设中水设施,而大部分高校和大部分三星级以上饭店适宜建设中水设施.

Due to water shortages,many districts and cities have started reusing wastewater as an inexpensive supplemental source of water.This study was conducted to evaluate the suitability of various sites for construction of decentralized wastewater reclamation facilities,to identify suitable conditions for reclaimed water reuse in various industries,and to provide helpful information for the formulation or revision of urban wastewater reclamation policies.To accomplish this,the factors influencing the construction of wastewater reclamation facilities were analyzed taking Beijing as an example.In addition,the suitability of wastewater reclamation by water consumers from government institutes,colleges and hotels in Beijing was evaluated after consideration of the water consumption of several consumers in each of these industries.The results indicate that most government institutes and one- and two-star hotels are not suitable,while most hotels of three-star or higher level and most colleges are suitable,for the construction of wastewater reclamation facilities.
