海绵城市径流雨水水质监测研究

Research on stormwater runoff quality monitoring in sponge city

海绵城市径流雨水水质监测是分析下垫面径流污染特征、评估海绵城市污染物控制效果、研究排水管道污染物迁移规律、分析受纳水体水质污染成因的科学手段和依据。针对径流雨水水质监测存在监测点位布置和采样方法不合理、水质监测指标不明确、采样时间及频次不确定等问题,分析总结径流雨水水质监测现状及国内外径流雨水控制标准,提出适用于设施、排水管网、受纳水体的监测位置和采样方法、水质监测指标、采样时间频次等建议。

Sponge city stormwater runoff quality monitoring is a scientific method and basis for analyzing the characteristics of underlying surface runoff pollution,evaluating the effect of sponge city pollutants control,studying the migration of pollutants in drainage pipes,and analyzing the causes of water pollution in receiving water bodies.Stormwater quality monitoring has problems such as unreasonable monitoring location and sampling methods,unclear water quality monitoring indicators,uncertain sampling time and frequency,etc.The current situation of stormwater runoff quality monitoring and stormwater runoff control standards at domestic and abroad are analyzed and summarized.Recommendations for monitoring location and sampling methods,water quality monitoring indicators,sampling time and frequency that applicable to facilities,drainage pipe networks,receiving water bodies are proposed.
