| 摘 要： | 选取页岩、粗砾石、铁矿石、麦饭石及其组合作为人工湿地填料，进行不同基质室内小试污水净化效果研究。结果表明：在相同进水水质和水力负荷运行条件下，单一填料页岩COD、TN、TP去除效果最好，去除率最高分别可达40％、88，9％、87．5％；组合填料COD去除率差别不大，页岩与粗砾石组合TN、TP去除率较高，分别可达到81．7％、71．9％。考虑到填料物理特性及长期稳定运行的需要，可选择页岩与粗砾石组合作为人工湿地去污填料。

| Abstract: | Shale,rough grave,ironstone,hornblendes,were selected for the packing of constructed wetland to carry out the researches on effect of sewage purification in lab by different substances.The results showed that,under the condition of the same influent and hydraulic loading of 200mm/d,single shale COD,TN and TP had the best removal effect;the removal rates were 40%,88.9%,and 87.5% respectively;COD removal rate of combined packing had no obvious difference;the removal rates of the combination of shale and rough grave were higher and reached to 81.7% and 71.9% respectively,for consideration of packing's physical characteristics and long-term and stable operation,the combination of shale and rough grave was selected as the packing for pollutant removal in the constructed wetland. |
