城市生态住宅小区分散式雨水人工湿地处理研究

以小区为单位的城市雨水分散式收集利用有利于减轻城市洪涝灾害，减小城市排水管网长度和管径，缓解城市供水压力，对改善城市水环境和生态环境具有重要意义。本文提出利用人工湿地处理小区地表径流并回用于城市地下水补给、绿化的思路，论述了城市雨水人工湿地再生处理利用系统中主要工艺的设计计算方法，为缓解城市用水压力提供有效途径。

Creating Artificial Wetland in Urban Residences With Rainwater

Community based rainwater collection in urban residences is helpful for reducing flood disasters, using shorter and smaller pipelines for urban sewage system and mitigating pressure on urban water supply. It has significant implications to urban water conditions and ecological environment. Proposals were made to utilize artificial wetland to collect surface run-off water and to use it as supplement for underground water and for growing plants in urban areas. The design of main parts of the artificial wetland system for rainwater collection was described in the paper. The artificial urban wetland system that collects rainwater would provide an effective way of mitigating pressure on urban water supply.
