Abstract

Abstract:

In order to study the effects of plants and substrate size grading on the treatment of polluted river water by the horizontal flow constructed wetlands(HFCWs),two groups of with/without plants,multsized grading HFCW reactors have been set up. The results show that the denitrification & dephosphorization results of the HFCWs which were planted with Phragmites australis are all better than that of the HFCWs which were not planted with plants. The joint action of the proportion of substrates having different sizes and plants can make the denitrification & dephosphorization results of the wetlands inner space have more uniformity. The proportion of direct adsorption of plants for nutrients in the overall of denitrification and dephosphorization in wetlands is 11.3% and 17.4%,respectively,which is slightly higher than the indirect facilitation of plants on other components in wetlands.

Key words: horizontal undercurrent, constructed wetland, substrate size grading

摘要：

为了研究植物和基质级配对水平潜流人工湿地处理污染河水营养物的影响,构建了有/无植物两组多粒径配比水平潜流人工湿地。结果表明,种有植物的水平流人工湿地的脱氮除磷效果均优于未种植植物湿地;通过基质不同粒径的配比与植物的联合作用可以使湿地内部空间的脱氮除磷效果更具有均匀性;植物对营养物的直接吸收在湿地脱氮、除磷总量中所占比例分别为11.3%和17.4%,且略大于植物对湿地其他组成的间接促进作用。
