水环境生态修复中人工湿地技术比较

介绍了人工湿地的功能和分类,并对表面流人工湿地、潜流人工湿地、单一垂直流和复合垂直流这几种技术的实现原理、技术特点及其相互关系做了详细的比较,同时就水平流、垂直流、混合流人工湿地的构建类型及其运行特征进行了比较,指出应根据实际污水的污染特征、对各处理指标如BOD,COD等的要求以及经济因素等来选择单一式或复合式的人工湿地类型.

Comparison of the Artificial Wetland Techniques in the Ecological Restoration of the Water Environment

This paper introduces the functions and classifications of the artificial wetlands, makes detailed comparison of the implement principle, the technical characteristics and the interrelation of several techniques such as the surface flow artificial wetland, subsurface flow artificial wetland, single vertical flow and fixed vertical flow artificial wetland, and also makes the comparison of the structure types and operation features of the horizontal flow artificial wetland, the vertical flow wetland and the fixed flow wetland, and pointed out that the single type or composite type of the artificial wetland should be selected according to the actual pollution features of the wastewater, the requirements of each treating target such as BOD and COD, and the economic factors, etc.
