城市小区雨水径流水质监测及特性分析

通过对上海理工大学校园区的不同下垫面产生的径流水质的监测,及其对污染主要影响因素与污染程度的分析表明,下垫面材料、降雨历时、降雨强度及降雨量等是小区雨水径流水质的重要影响因素。小区径流水质的主要污染为有机污染及悬浮固体污染,且有机污染指标COD、悬浮固体污染指标SS、浊度随径流历时的变化满足指数方程。

Quality Monitoring and Property Analysis of Runoff in Urban Residential Area

By monitoring of runoff quality as well as analysis of its affecting factors and pollution level of the runoff from different underlying surfaces in residence of campus of Shanghai University of Science and Technology,results indicated that the important affecting factors were underlying surface materials,rainfall duration,rainfall intensity and volume,with organic pollutants and suspended solids as major pollutants of the runoff.Following the change of runoff duration,organic pollution index COD,suspended solid pollution index SS and turbidity were satisfied with index equations.
