摘要：

设置了不同基质 (砾石、加气混凝土) 及是否种植美人蕉的不同人工湿地结构, 通过小试实验对比各个工况对雨水径流污染的阻控效果. 研究发现, 加气混凝土与种植美人蕉的人工湿地组合成本略高 (4.20元/工况), 较其余工况高出1.00 ~ 2.90元/工况, 但在运行的两个周期 (交替运行30 h, 落干48 h) 内, 对${\rm{NH}}_4^+$-N、${\rm{NO}}_3^- $-N、TN、${\rm{PO}}_4^{3-} $、TP和CODCr的平均去除率分别为73.3%、47.0%、85.4%、56.4%、76.0%和65.5%, 平均高出其余工况10.9% ~ 18.8%, 效果最优, 性价比最高, 适于推广应用.

Abstract:

In this study, constructed wetland structures were established using different substrates (gravel and aerated concrete), with or without cannas planting. Subsequently , the effects of different working conditions on rainwater runoff pollution were investigated through small experiments. The cost of the constructed wetland with aerated concrete and cannas (4.20 yuan/working condition) was slightly higher (1.00 ~ 2.90 yuan/working condition higher) than those under other working conditions. However, in both cycles of operation (i.e., alternating operation for 30 h and drying for 48 h), the average removal rates of ${\rm{NH}}_4^+ $-N, ${\rm{NO}}_3^- $-N, TN, ${\rm{PO}}_4^{3-} $, TP and CODCr were 73.3%, 47.0%, 85.4%, 56.4%, 76.0%, and 65.5%, respectively. These values were higher than those under other working conditions by an average of 10.9% ~ 18.8%. Thus, this constructed wetland structure had the best effect and the highest cost performance. Therefore, it is suitable for promotion and application.
