摘　　要：潜流人工湿地是人工湿地的主要类型,湿地梯级净化效果需要进一步研究。以官厅水库黑土洼地湿地系统示范工程为研究对象,通过近4 a实验,总结得出湿地对各类污染物的梯级净化效果。分析结果表明,人工湿地示范工程对水质净化效果较为明显,各个主要污染物的去除率平均达到40%以上;前两级湿地污染物的去除率占总去除率的比例大部分达到50%以上;潜流人工湿地具有进一步净化水质的潜力。基于分析结果,对于北方人工湿地的建设提出了有指导价值的建议,并指出了今后的研究方向。Subsurface flow constructed wetland is the main type of the constructed wetland,and further study needs to be carried out on the stepped water quality purification effect.By taking black soil low-lying ground of Guanting Reservoir as the research object,through nearly 4 years′ experiments,the stepped water quality purification effect of different pollutants of the wetland is researched.The research result shows that the water quality purification effect of the constructed wetland is relatively obvious,and the average removal ratio of the main pollutants is above 40%;the first and second steps have the largest capability of water quality purification,and the ratio of most of their removal ratio to the total wastewater removal rate is basically over 50%;the wetlands have further potential for water purification.Based on the results,the suggestions for the construction of artificial wetlands in North China and research direction are proposed,and the further research direction is pointed out.
