摘要
选择贵州省正常运行状态下的3种不同植物配置的生活污水处理人工湿地,定期测定污水中的化学需氧量(COD)、生化需氧量(BOD)、磷酸盐、氨氮、总磷(TP)等水质因子。结果表明,香蒲(Typha orientalis Presl)+茭白(Zizania latifolia)+美人蕉(Canna indica)+水葱(Scirpus validus Vahl)+睡莲(Nymphaea tetragona Georgi)的植物配置对COD、磷酸盐的去除率最高,分别为86.36%、73.20%;BOD的去除率以水葫芦(Eichoimia crassips)+风车草(Cyperus alternifolius)+美人蕉+再力花(Thalia dealbata)+香蒲植物组合为最好,达到81.28%;氨氮、总磷的去除率以风车草+再力花+菖蒲(Acorus calamus Linn.)+千屈菜(Lythrun salicaria)+水葫芦+美人蕉+花叶芦竹(Arundo donax var.versicolor)的植物组合为最高,分别为75.96%和72.28%。
Three plant combination kinds of constructed wetland in operation were chosen in Guizhou province. Their capability to remove nutrients, such as chemical oxygen demand（COD）, total phosphorous（TP）, ammonia nitrogen（NH4＋-N）,biochemical oxygen demand（BOD）, and phosphate in constructed wetland systems, were analyzed. The results demonstrated that the plant combination of Typha orientalis, Zizania caduciflora, Canna indica, Scirpus validus Vahl and Nymphaea tetragona Georgi had the highest in removing COD and phosphate, being 86.36% and 73.2%, respectively. As for the removal of BOD, the plant combination of Eichhornia crassipes, Cyperus alternifolius, C. indica, Thalia dealbata and T. orientalis Presl was the highest, being 81.28%. The highest of removal of NH3-N and TP was 75.96% and 72.28% in FX plant combination, respectively. This plant combination was made up of C. alternifolius, T. dealbata, Acorus calamus Linn.,Lythrum salicaria, E. crassipes, C. indica and Arundo donax var.versicolor.
