| 关 键 字：人工湿地 污水处理 植物吸收 运行问题 |
| 摘 要：对深圳石岩河人工湿地运行以来的污水净化效果、植物生长状况和处理系统存在的问题等进行了分析和研究。结果表明,湿地运行7个月,污水处理量达1.8×106m3,对污水中CODCr、BOD5、SS、TP、TN和NH3-N的去除率分别为87.1%、94.1%、57.5%、91.4%、47.8%和74.8%。对植物氮磷的分析表明,植物氮质量分数在1.31%~2.25%之间,磷质量分数在0.40%~1.15%之间,植物氮积累量为116.2~417.1kg.hm-2,磷积累量为70.7~178.3kg.hm-2。与工程总处理量相比,植物吸收的氮磷量仍占很小部分,平均分别为4.90%和3.78%。此外,对工程运行状况的观测发现,人工湿地存在工程表面板结、内部堵塞及植物管理等问题,板结程度与植物覆盖度成反比。 |
| 关 键 字(英文)：constructed wetland wastewater treatment plant uptake practical trouble |
| 摘 要(英文)：Shiyanhe Constructed Wetland of Shenzhen, locating in Shiyan town of Shenzhen city, has been under operation since July 2003. After 7 months’ treatment(from July, 2003 to Feb, 2004), over 1.8×106 m3 wastewater had been treated, and the main pollutants CODCr, BOD5, SS, TP, TN and NH3-N decreased by 87.1%, 94.1%, 57.5% , 91.4%, 47.8% and 74.8%, respectively. The research on the nutrients in the plant tissues suggests that the content of N reached 1.31% ~ 2.25% and content of P reached 0.40% ~ 1.15%, and the uptake amount got to 116.2 ~ 417.1 kg.hm-2 and 70.7 ~ 178.3 kg.hm-2 accordingly. However, the plants only con- sumed a small amount of the total pollutants removed by the wetland, with an average of 4.90% for N and 3.78% for P. Furthermore, the investigation also detected some problems in the wetland system such as surface hardening, jamming and plant management, and surface hardening is opposite to plant coverage. |
