| 摘 要： | 研究了西南地区常见植物麦冬在纯土、沙土、沙土粉煤灰基质中对生活污水的净化效率，并讨论了不同流量对净化效率的影响．结果表明：麦冬人工湿地系统在不同的基质中对各污染物指标的净化效率都较好．在相同流量下，麦冬人工湿地在沙土粉煤灰系统中对城市生活污水的TP、CODcr、NH4^＋-N和浊度的净化效率最佳，在沙土系统中对城市生活污水的TN的净化效率最佳，在纯土系统中对各项指标的净化效率相对较差．当通入污水的流量为1L／d时，达到最佳净化效率，流量为3L／d时净化效果相对稳定．由此，考虑到与实际应用相联系，麦冬人工湿地对城市生活污水的净化流量可选择3L／d，在考虑人工湿地基质时可选用沙土粉煤灰．

| Abstract: | The purification efficiency for the city life sewage by using wintry wheat artificial wetland was investigated with various flux and bedding filling of pure soil,sandy soil and sandy soil mixed with pulverized coal ash.The results show that all the artificial wetland of Dwarf Lilyturf Tuber with various bedding filling has better purification efficiency,specially the sandy soil mixed with pulverized coal ash is the best in removing the TP,CODcr,NH4+-N and the turbidity,and the sandy soil is the best in puri... |
