摘要
介绍了中国城市径流污染状况,指出径流污染控制应纳入污染物总量控制范畴。介绍了国外径流污染控制量及控制参数的确定方法。对中国31个主要城市近30年的降雨资料(降雨量日值)进行了统计分析,得出径流污染控制量(WQV)的设计降雨量,为中国各城市实施径流污染控制提供了量化参数。同时指出,WQV的设计降雨量也可以作为设计雨水收集利用设施经济规模的一个很好的参考值。
The Chinese urban runoff pollution status is introduced, and it is recognized as a main part of total pollutant control. The determination methods for runoff pollution control quantity and its control parameter in several countries are presented. The statistical analysis was made on 30-year daily rainfall data for 31 cities in China, and the design rainfall for runoff pollution control quantity was deduced,providing a quantization parameter for Chinese urban runoff pollution control. The design rainfall for runoff pollution control quantity can be considered as a good reference value in design of rainwater harvesting and utilization facilities.
