长三角城市群雨水径流水质污染特征与控制技术分析
Analysis of Rainwater Runoff Pollution Feature and Pollution Control Technologies of Yangtze River Delta Urban Agglomerations
摘要
Abstract
[Objective]The water pollution caused by rainfall runoff in the Yangtze River Delta urban agglomeration is complex and increasingly severe.[Methods]This study integrates experimental and literature data to systematically explore the characteristics and relationships of rainwater runoff pollution in typical underlying surfaces and functional areas of Yangtze River Delta cities.The dataset cover 18 cities in the Yangtze River Delta region,including three types of underlying surfaces(roads,roofs,and green spaces),five types of urban functional areas(transportation,residential,commercial,industrial,and cultural and educational areas).[Results]The result indicate that chemical oxygen demand(CODCr),suspend solids(SS),and total phosphorus(TP)are the key indices for controlling road runoff pollution,while TN and ammonia nitrogen,CODCr and SS are the indices that need to be controlled in roof and green space runoff,respectively.Pearson correlation analysis shows that CODCr is positively correlated with SS and TP on the road(r＞0.5).SS is positively correlated with CODCr,ammonia nitrogen is positively correlated with TN on the roof.And ammonia nitrogen is positively correlated with CODCr and TP on the green surface.This study provides a scientific basis for the coordinated reduction of multiple pollutants in rainfall runoff control and analyzes the technologies and future development trends.[Conclusion]This study fills the gap in the systematic research on the characteristics of rainfall runoff pollution in the Yangtze River Delta urban agglomeration,and provides data and scientific basis for the collaborative treatment of non-point source pollution.关键词
