摘要

[目的] 分析改良绿地介质对污染物削减的影响因素，以期为海绵城市的绿地建设提供科学参考。[方法] 通过室内模拟试验，探究绿地土壤〔土：砂：椰糠（4：4：2）+1% PAM〕在降雨重现期、淋溶时间以及深度因素综合影响下对污染物的截留特征。[结果] 不同污染物种类在改良介质中影响的主要因素会因污染物种类的不同而不同。其中深度因素对氮、化学需氧量（COD）的淋溶浓度贡献率较大，降雨重现期因素对磷淋溶浓度贡献率较大。氮、COD淋溶浓度随时间的变化的降低趋势可用幂函数或指数函数表示，磷淋溶浓度随时间变化呈现出先减小后增大的趋势。氮、COD整体淋溶浓度随降雨重现期和深度增加整体均表现出增加的趋势。而磷淋溶浓度随降雨重现期的增加表现出增加的趋势，随深度的增加表现出降低的趋势。整体来说，土：砂：椰糠（4：4：2）+1% PAM改良介质对磷削减能力较强，对氮、COD削减能力较弱。[结论] 土：砂：椰糠（4：4：2）+1% PAM改良介质能够有效截留雨水中磷污染物，可应用于海绵城市绿地建设。

Abstract

[Objective] The factors affecting the reduction of pollutants by improved green space media were analyzed

in order to provide a scientific reference for the construction of green space in sponge cities.[Methods] This experiment investigated the pollutant retention characteristics of urban green space[soil:sand:coir (4:4:2) + 1% PAM] under the combined influence of the repetition period of rainfall

leaching time and depth through indoor simulation experiments

with a view to providing some reference for greenfield construction in sponge cities.[Results] The main factors affecting the different pollutant types in the modified media varied depending on the pollutant type. Among them

the depth factor had a greater contribution to the leaching concentration of nitrogen and COD

and the repetition period of rainfall had a greater contribution to the leaching concentration of phosphorus. The decreasing trend of nitrogen and COD leaching concentration over time could be expressed by a power function or an exponential function. Phosphorus leaching concentration changed with time

showing a trend of first decreasing and then increasing. The overall leaching concentration of nitrogen and COD showed an increasing trend with the increase of the repetition period of rainfall and substrate depth. The phosphorus leaching concentration showed an increasing trend with the increase of the repetition period of rainfall

and showed a decreasing trend with the increase of the depth. On the whole

soil mixed with sand and coir (4:4:2) + 1% PAM had a stronger ability to reduce phosphorus

but a weaker ability to reduce nitrogen and COD.[Conclusion] Soil mixed with sand and coir (4:4:2) + 1% PAM improved medium can effectively intercept phosphorus pollutants in rainwater

and can be used in the construction of sponge urban green space.
