Capacity,多数再生水厂生产销售量明显低于设计能力 Actual production/sales much lower than design capacity普遍缺乏足够用户 Commonly shortage of users管网不足 Distribution pipelines shortage 不合理水价 Unreasonable water tariff水质问题 Water quality problem水资源管理问题 Improper water resource management成本回收问题 Cost recovery difficulty 用户发展成为主要任务 User development becomes a major task需要生产者及政府的共同努力 Needs joint efforts of suppliers and government,再生水系统：采用集中型还是就地就近型？Centralized system or onsite/point-of-sale system？,集中型系统的限制因素 Constraints of Centralized system管网投资高（北京）High pipelines costs，Beijing难以同时满足不同用户的水质和水量需求 Difficult to simultaneously meet the various users requirements in quality and flow-rate适合污水厂周围 Better for applications near WWTP适合水质要求相同的批量用户或大水量用户 Better for similar quality requirement&larger demand就地就近型系统 Onsite/point-of-sale system 集中与就地/就近相结合 Combination of both systems,再生水法规支持体系与综合管理机制Legal supporting system&management mechanism,建立相关法规、政策与标准，进行指导与督查 Establish relevant regulations,policies and criteria/standard for guidance and enforcement再生水规划纳入城市总体规划和水资源规划 Water reuse plan being part of city master plan&water resource utilization plan污水处理目标由达标排放转变为再生循环 Strategic objective shift from“discharge-standard”to the“water reclamation and recycling”,再生水标准 Reclaimed water standards,经历多次修订 Modified several times存在需要修订之处 Some irrationality still exist.再生水基本分类水质标准建议 Proposal for basic
