摘要:
Subtropical climatic conditions can contribute to the death of the aerial parts of constructed wetland plants in winter. This presents a barrier to the widespread application of constructed wetland and is an issue that urgently needs to be solved. Three contrasting experiments, the plant-intercropping model (A), the warm-seasonal plant model (B), and the non-plant model (C), were studied in terms of their efficiency in removing pollutants, and the change in root structure of plants in the plant-intercropping model within the vertical-flow constructed wetlands. The results indicate that model A...
摘要(中文):
副热带的气候的条件能在冬季贡献构造沼泽地工厂的天线部分的死亡。这介绍一个障碍给构造沼泽地的普遍申请并且是着急地需要被解决的一个问题。三形成对照实验,杂种植物的模型(A) ,温暖季节的工厂模型(B) ,和非植物为(C) 建模,在在垂直流动的构造沼泽地以内在杂种植物的模型在工厂的根结构移开污染物质,和变化以他们的效率被学习。结果显示模型 A 能解决上述的问题。总的来说,平均三种污染物质的移动率(货到付款 < 潜水艇 class= “ a-plus-plus ” > Cr , 总数氮(TN ) 和总数磷(TP )) 用模型, A 比用模型 B 和 C 获得的那些显著地高(P < 0.01 ) 。而且,处于三种污染物质的移动率的重要...
