| 摘 要： | 利用垂直复合流模拟人工湿地系统对城市污水厂尾水进行深度处理实验研究,植物床选用美人蕉、菖蒲、茭草、芋头和象草混合栽种,采用石英砂为主体填料。实验研究表明:人工湿地系统在停留时间为24h,水力负荷为0.4m3(m2·d)的运行条件处理效果较佳,在此条件下连续稳定运行10个月,处理后的尾水主要指标达到(GBT189212002)标准。

| Abstract: | Integrated vertical-flow constructed wetland was used in this investigation for advanced treatment of municipal sewage effluent.Canna,calamus,wild rice and elephant grass were selected as constructed wetland plants and quartz sand was selected as filling.It is shown that the optimal running conditions with hydraulic residence time of 24 h,with hydraulic loading of 0.4 m~3/(m~2·d) were determined.After 10-month operation,the main indexes of the effluent can meet “Water Quality Standard for Scenic Environment of Urban Recycling Water”(GB/T18921-2002). |
