| 摘 要： | 在低温季节,利用人工地面廊道对微污染河水进行净化处理。结果表明,砾石廊道系统对微污染河水中的COD、氨氮、色度具有稳定的去除率,其去除率分别为70%、90%、75%;硝酸盐氮的去除率不高,主要是受温度的影响;廊道的第三段对氨氮、硝酸盐氮、色度的去除效果不明显。中试实验表明,人工地面廊道对微污染河水中的污染物质有明显的净化效果,确定廊道的最优湿地床长度将促进其实际工程应用。

| Abstract: | Micro-polluted river water was purified by artificial surface corridor in the low temperature season.The results showed that the removal rate of COD_ Cr,NH_3-N,and chromaticity in micro-polluted river water purified by gravel corridor system was 70%,90% and 75%,which was a stable level.The removal rate of NO_3-N was low because of the low temperature.The removal effect of NH_3-N,NO_3-N, and chromaticity in the third part of the corridor was not satisfactory.Artificial corridor had a good effect on purifying micro-polluted river water and the optimum length of corridor could promote the use of artificial corridor in actual projects. |
