| 摘 要： | 在间歇运行条件下,采用复合垂直流人工湿地净化污水处理厂二级出水,考察了其净化效果及影响因素.结果表明,该系统能够有效降低污水厂二级出水中的氮和磷,适用于城市污水的深度处理.在0.4 m~3/(m~2·d)的低水力负荷条件下,系统对COD、氨氮、总氮和PO_4~(3-)P的去除率分别为87.4%、82.15%、60.32%和30.15%;当排空时间为2 h时,系统的处理效果最好,对氨氮、总氮、PO_4~(3+)-P的去除率分别为84.44%、65.46%和40.33%. |
| 关 键 词： | 复合垂直流人工湿地 污水厂二级出水 水力负荷 排空时间 |

| Abstract: | The integrated vertical-flow constructed wetland under intermittent operation condition was used for purification of secondary effluent from WWTP, and the purification efficiency and the influencing factors were investigated. The results show that the system can remove the nitrogen and phosphorus in secondary effluent from WWTP and is suitable for advanced treatment of municipal wastewater. Under low hydraulic load of 0.4 m~3/(m~2·d), the removal rates of COD, NH_3-N, TN and PO_4~(3-)P are 87.4% , 82.15%, 60.32% and 30.15% respectively. When the optimum idle time is 2 h, the removal rates of NH_3-N, TN and PO_4~(3+)-P are 84.44%, 65.46% and 40.33% respectively. |
| Keywords: | integrated vertical-flow constructed wetland secondary effluent from WWTP hydraulic load idle time |
