摘　　要：介绍了国内外雨水收集利用的情况,并针对北京水资源短缺和雨水资源大量浪费的现状,分析了北京市雨水资源收集和综合利用的前景,提出削减污染以及雨水综合利用的相关措施。北京天然雨水较清洁,然而经过在各种下垫面的冲刷后径流水质变差,初期径流污染物的含量相当大,甚至超过地表水环境质量标准的Ⅴ级。建议将初期降雨径流和后期雨水分开对待,将初期径流处理后再利用。The collection and usage of rainwater at home and abroad was discussed,and the actuality of water shortage and waste of rainwater in Beijing were analyzed.After analyzing the perspective of rainwater resource collection and comprehesive usage,it also brought out several precaution measures of pollution reducing and rainwater usage.Natural rainwater was comparatively pure,but heavily polluted after its washing the underlying surfaces in the city.The concentration of pollutants in the initial flush was especially high,even exceeding the fifth level of the environmental quality standards for China.The initial flush should be separated from the total runoff,and be used after treatment.
