官厅水库人工湿地系统水质净化效果研究

Studies on water purification of artificial wetland of Guanting Reservoir

官厅水库黑土洼人工湿地系统经过一年多的运行,经历了严寒冬季的考验,获取了1万多组监测数据。通过对BOD5等指标去除率分析,人工湿地对Orth-D、TP、CODMn去除率较多,TN、NH4+-N、NO-3-N处理效果一般。建议二期工程进一步改进工艺,促进有机物的降解。

After more than one year＇ operation, Heituwa Artificial Wetland of Guanting Reservoir experienced the test of cold winter, and more than 10,000 groups of monitoring data were obtained. After assessment of removal efficiency of BOD5 and other indexes, it is found that the removal efficiencies of the wetland on Orth-D, TP, CODMn are relatively high, but the removal efficiencies of TN, NH4^＋-N, NO^-3-N are low. It is recommended to improve technology and degradation of organic matter.
