摘要
在介绍江苏双灯纸业集团公司利用人工湿地塘床系统处理废水的工艺过程和运行情况的同时,分析了该系统净化污染物的机理及生态环境效益.分析结果表明,人工湿地塘床系统不仅对特征污染物指标CODCr,BOD5和SS等具有较高的去除率,还通过出水灌溉芦苇降低了土壤盐渍化程度,并且湿地中生长的芦苇可作为造纸原材料回收利用,同时人工湿地形成了独特的生态环境,既改善了局部景观,又保护了野生环境.
An introduction was given to the operating condition of the pond-bed system and the technical process of its application to wastewater treatment in Jiangsu Shuangdeng Paper Company, and the mechanism of pollutant purification and eco-environmental benefits of the system were also analyzed. The results show that the man-made wetland pond-bed system has high removal rate of some characteristic pollutants, such as COD_(Cr), BOD_5, and SS, and also decreases the level of soil salinization by effluent water irrigation of reed. The reed growing in wetland can be taken as paper-making materials, which will produce a certain benefit. Meanwhile, the unique eco-environment formed by man-made wetland system improves the local landscape, and protects the wild habitat environment.
