海绵城市建设中校园等封闭区域雨水收集与利用

Collection and Utilization of Rainwater in Closed Area Such as Corpusin the Construction of the Sponge City

指出了校园等封闭区域雨水收集与利用是海绵城市建设的重要内容之一,其雨水收集与利用应符合当前经济发展、社会发展和科技发展的需要。雨水经收集、沉淀、净化、消毒、储存可以作为冲厕、洗路、浇花、水景等非饮用水使用,雨季可以降低校园等封闭区域雨水对城市公共排水管网的压力;同时可以降低对土壤的冲刷、减少水土流失;再者可以节约用水、提高自然资源利用率、改善人居环境质量。雨水收集与利用系统由雨水管道、收集过滤、净化消毒、贮存蓄水、自冲洗、雨水利用等主要部分组成,在建设实践中技术成熟、经济适用、安全可靠,值得推广应用。

Rainwater collection and utilization in closed areas such as campuses are one of the most important contents of sponge city construction.The collection and utilization of rainwater are consistent with the current economic development,social development and scientific and technological development.Rainwater can be used as non-potable water such as flushing,road washing,watering,water feature after rainwater harvesting,sedimentation,purification,disinfection and storage.Rainy season can reduce the pressure of urban public drainage network on rainwater in enclosed area such as campus;meanwhile,it can reduce soil erosion;In addition,water can be saved toimprove the utilization of natural resources and improve the living environment quality.Rainwater collection and utilization system consists of rainwater pipeline,collection and filtration,purification and disinfection,storage and storage,self-flushing and rainwater utilization.The rainwater harvesting and utilization system is worthy of popularization and applicationwith mature,economical,safe and reliable characteristics in construction practice.
