摘要:
通过构建标准转输型植草沟（GS）和改良型干植草沟（MBS），结合羟基铝蛭石污泥颗粒填料，对植草沟在校园雨水径流污染控制方面的应用效果进行了实地监测和分析。结果显示，相比标准转输型植草沟，改良型干植草沟对雨水径流中TSS、COD、氮、磷等污染物的去除效果更显著；植草沟的出流位置不同，对污染物的去除效果和机制也不尽相同，上表面出流的GS与MBS对径流污染物的去除效果相当，净化机制主要为植被截留吸附和土壤下渗作用，而下渗管出流的MBS主要利用生物填料层的过滤、吸附、截留等作用去除径流污染物，去除效果更优。
Abstract:
In this study, the efficacy of grass swale in mitigating campus stormwater runoff pollution was systematically monitored and analyzed through establishing a standard transfer-type grass swale and a modified dry grass swale packing with hydroxy-aluminum vermiculite sludge particles. In comparison to the standard transfer-type grass swale, the modified dry grass swale demonstrated a markedly superior efficacy in removing total suspended solids（TSS）, chemical oxygen demand (COD), nitrogen, phosphorus, and other pollutants from stormwater runoff. The pollutants removal performance and mechanism varied depending on the discharge positions within grass swale. The standard transfer-type grass swale and modified dry grass swale with upper surface outflow exhibited similar efficacy in mitigating runoff pollutants, primarily through vegetation adsorption and soil infiltration. Conversely, the modified dry grass swale with infiltration pipe outflow leveraged the capabilities such as filtration, adsorption, and interception of the biological packing layer to achieve superior pollutants removal performance.
