【摘要】 采用潜流式人工湿地系统对其在处理、控制暴雨径流污染问题进行了模拟研究,实验中人工模拟暴雨径流污染物浓度平均为CODcr291.23mg·L-1、TN26.08mg·L-1、TP1.38mg·L-1。实验结果表明,菖蒲-沸石湿地系统有较好的综合净化能力,去除率平均为CODcr87.13%、TN97.33%、TP77.29%。更多还原

【Abstract】 In consideration of stormrunoff pollution problems existing in many wa tersheds in our country,we utilized subsurface flow constructed wetlands to research th e problems.In an experiment,the ave rage concentrations of contaminant s in artificial stormwater were found to be:COD Cr 291.23mg ·L -1 ,TN26.08mg ·L -1 ,and TP 1.38mg ·L -1 ,respectively.According to our results from the present research,the best overa ll removal efficiency is found in an a corus calamus -zeolite system,having average removal rates:87.13%for COD Cr ,97.33%for TN,and 77.29%for TP,respectively.更多还原
