| 摘 要： | 从人工湿地水生植物根系实际生长深度、微生物及酶的空间分布以及不同深度人工湿地对污水的净化效果比较出发，研究了人工湿地污水处理系统的净化空间，以种植香蒲Typhaangustifolia和灯心草Juncuseffusus的人工湿地为例，水生植物根系主要分布在湿地基质上层25cm区域；微生物的数量随深度增加而递减，且35cm层的数量远远的低于上层；5－10cm层的磷酸酶、纤维素酶和蛋白酶活性亦大于20cm层；60cm深的人工湿地与20cm深的人工湿地对污水中污染物的净化效果基本一致。可以推断，人工湿地在净化污水的过程中，其上层存在一个较佳的净化空间。

| Abstract: | Dealt with the growing depth of macrophytes roots, spatial distributions of microorganisms and enzyme in artificial wetland and comparison of removal rates of contaminants in different depths of artificial wetlands, the better purifying space in artificial wetland wastewater treatment system has been discussed.From studies on the artificial wetland with cattail (Typha angustifilia) and rush (Juncus effusus), roots of macropyhter are distributed mainly over 25cm up surface in wetland, spatial distribution of microorganisms is as follows. The numbers of 5 - 10cm depth are more than the 20cm depth's and further more thanthe 35cm depth' s. The activity of phosphatase, glucan dehydratase and proteinase in surface is higher than 20cm depth's. In winter, the performance of purifying wastewater of the wetland which deeps 20cm shows almost no difference with the wetland which deeps 60cm.It may be deduced that there is a better purifying space in the upper level of artificial wetland for wastewater treatment. |
