| 摘 要： | 研究了以锰砂为填料的垂直流人工湿地处理钢铁废水的效果,试验结果表明:湿地系统对CODCr、Fe、Mn、TP、NH3-N的平均去除率分别为52%、97%、94%、95%和83%.夏季湿地对各种污染物的去除效果最好.HRT在2～5 d时,其改变对污染物的去除影响很小,低温条件对NH3-N的去除效果有一定的影响.对以Fe、Mn、浊度的去除为目的的人工湿地而言,在南方的冬季仍可达到良好效果.

| Abstract: | A pilot constructed vertical-flow wetland with manganese greensand media was researched for wastewater treatment in steel industry. The results showed that the average removal efficiency of CODCr, Fe, Mn, TP and NH3-N in the wetland system were 52%, 97%, 94%, 95% and 83% respectively. The best performance was achieved in summer. The change of HRT showed little effect on the removal of pollutants as it changed from 2 to 5 days. The removal of NH3-N was influenced by low temperature. As conclusion, we believed that constructed wetland could remove Fe, Mn and turbidity satisfactorily even in winter in south part of this country. |
