水资源匮乏已经成为人们目前面临的严重危机之一,水资源的供需矛盾日益突出,雨水的收集利用则是缓解这一问题的有效措施之一。建筑屋面的雨水经收集处理后可用于水质要求较低的城市杂用水,从而大大减少自来水的用量,节约宝贵的饮用水资源。微絮凝/盘式过滤器工艺用于雨水回用处理系统,对SS、浊度、TP和铁都有较好的处理效果。在试验水质条件下,PAC 投加量为15 mg/L时,微絮凝/盘式过滤工艺的出水水质基本满足回用水水质要求。

At present,water scarcity has become the serious crisis facing human being.Rain water harvesting and reuse is one of the effective measures to solve the contradiction between water resource and water consumption.Rainwater on architecture roof could be used as the grey water af-ter collection and treatment,which would decrease the requirements on tap water and save the pre-cious water resource.Micro-flocculation/disc filter could be used in rainwater reclamation system and its performance showed satisfying removal on SS,turbidity,TP and iron.In the experiment, when the PAC dosge was 1 5 mg/L,effluent from micro-flocculation/disc filter could meet the re-quirements of water quality of reuse.
