摘　　要： 通过在垂直流模拟人工土柱上种植不同的花卉植物,研究了垂直流花卉人工湿地对污水COD、BOD5、TN和TP的净化效果的影响。结果表明,所选用的5种陆生花卉,甚至鲜切花卉对化粪池污水有比较好的净化效果,它们对BOD5的去除率可达到92.04%以上,对TP的去除率甚至可达到97.77%以上。而且种植花卉植物的人工湿地出水水质要好于不种植物的对照湿地系统。 Different flowers and plants were planted in simulated vertical flow flower constructed wetlands. The effects of flowers and plants of constructed wetland on the purifying efficiency of wastewater for COD, BOD5 , TN and TP were studied. The results showed that the removal effieieneies of COD, BOD5 , TN and TP were significantly different with hydraulic loading rate. The removal rates of BOD5 and TP by simulated systems were 92.04% , and 97% , respectively. It was also found that the effluent quality of vertical-flow constructed wetland with flowers and plants was better than that of those vertical flow constructed wetland without flowers and plants.
