垂流式人工湿地处理官厅水库入库水研究

Study on Treatment of Guanting Reservoir Inflow on Vertical Flow Constructed Wetlands

在官厅水库永定河入库口处进行了垂流式人工湿地对入库河水的净化试验 ,结果表明 ,在渗滤时间 <1h时垂流式人工湿地对河水就有较好的净化效果 (对有机污染物和NH+ 4 -N的去除率都能达到 80 %左右 ,对TN和TP的去除率为 40 %左右 )。

Field experiment was made at the entrance of Yongdinghe River into the Guanting Reservoir on the treatment of reservoir inflow water by the vertical flow constructed wetlands.Experimental data indicated that when hydraulic retention time is less than one hour,the vertical flow constructed wetland has better purification results on river water,that is,the removal rate of organics and NH + 4-N can reach about 80%,and TN and TP about 40%.
