| 摘 要： | 通过构建于新沂河河漫滩上的表面流人工温地系统处理污染河水的现场中试研究表明,在CODMn和NH4 -N进水浓度分别为11．69-60．00 mg／L和1．37-20．18 mg／L时,种植千屈菜、美人蕉、香蒲、水葱4种不同植物的表面流人工湿地系统,对CODMn的平均去除效率分别为26．44％、40．12％、46．71％、28．23％,对NH4 -N的平均去除效率分别为64．27％、70．49％、66．78％、58．52％,其中香蒲和美人蕉的净化能力较强．4种植物中水葱的耐淹能力最强,在完全淹水达22 d以上时,水葱依然生长良好;千屈菜的耐淹能力最弱,在完全淹水7 d后就开始枯萎,淹水17 d后地上、地下部分全部死亡．

| Abstract: | Treatment of polluted river water with variations of water quality using pilot-scale Surface Flow Constructed Wetland (SFCW) in Xinyi River Floodplain,Jiangsu Province was studied in this paper. The main results show that:When the influent concentrations of CODMn, and NH4 -N were 11. 69 -60. 00 mg/L and 1. 37 -20. 18 mg/L, the CODMn and NH4 -N removal rate of SFW which planted Lythrum salicaria, Canna indica, Typha latifolia and Scirpus locustris were 26.44% ,40. 12% ,46. 71% ,28.23% and 64. 27% ,70.49% ,66. 78% ,58. 52% ,respecfioely. Typha latifolia and Canna indica have stronger ability for purifying pollutants. Scirpus locustris has the strongest ability of inundation,it can resist inundation of over 22 days and still live. Lythrum salicaria has the lowest ability of inundation, it only can resist inundation of 7 days. |
