| 摘 要： | 本文研究了水力负荷对抚仙湖北岸典型人工湿地净化河道污水处理效率的影响。研究表明,TN、TP及SS去除率随着水力负荷的增加而下降,COD去除率受水力负荷的影响程度相对较小。综合考虑水力负荷对氮磷、有机物及悬浮物等水质净化效果的影响,如果不考虑其它因素,仅从系统处理效果的角度选择水力负荷,人工湿地系统的最佳水力负荷为0.5 m3/m2·d以下。

| Abstract: | This paper studies the influence of hydraulic loading on river channel purification and sewage treatment efficiency of constructed wetland in the north shore of Fuxian Lake. The results showed that the removal rates of TN, TP and SS were in inverse proportion to the hydraulic loading, and that of COD had less impact by hydraulic loading. Considering the influence of hydraulic loading on the purification effect of the constructed wetland on nitrogen and phosphorus, organics, suspended solids and etc. , if only choose hydraulic loading from the treatment effect, the best hydraulic loading of constructed wetland system was below 0. 5 m3/m2 · d without considering other factors. |
