| 摘 要： | 以柳叶马鞭草、菖蒲、鸢尾和美人蕉及南方红壤构建5个生物滞留池模拟装置,研究植物和IWS(内部存水区)及其交互作用对径流中TSS、COD、NH_3-N、NO_3~--N、TN和TP去除的影响,定期测定植物的叶绿素含量、株高和游离脯氨酸含量等生理指标,以探讨植物的生长适宜性。结果表明:植物对COD、NO_3~--N和TN的去除影响较大,其去除率分别为68.84%~77.28%、13.09%~59.61%和42.41%~71.75%,柳叶马鞭草和美人蕉的NO_3~--N及TN去除能力显著高于菖蒲和鸢尾(P柳叶马鞭草>鸢尾>菖蒲,美人蕉和柳叶马鞭草的去污效果和长势较好,适宜在南方生物滞留池中种植。

| Abstract: | Five simulated bioretention devices were structured by Verbena bonariensis,Acorus calamus,Iris tectorum and Canna indica and red soil of southern China,the effects of plants and IWS and their interaction on runoff pollutant (TSS,COD,NH3-N,NO3-N,TN and TP) removal were studied,and the chlorophyll content,plant height and free proline content of plants were measured on a regular to research growth suitability.The results showed that:Plants had greater effect on removal efficiency of COD,NO3-N and TN,whose removal rate were 68.84％ ～77.28％,13.09％ ～ 59.61％ and 42.41％ ～ 71.75％,the NO3-N and TN removal ability of Verbena bonariensis and Canna indica were significantly higher than Acorus calamus and Iris tectorum (P ＜ 0.05),COD removal ability of Canna indica were significantly higher than Iris tectorum(P ＜0.05);plant had no obvious effect on the removal of TSS,NH3-N and TP,whose removal rate were 97.10 ～98.09％,81.96 ～ 85.50％ and 90.68 ～ 94.45％;The removal rates of COD,NO3-N and TN increased by 6.64％,9.43％ and 7.68％ when IWS was installed,the removal rate of TSS,NH3-N and TP changed slightly,interaction of plant and IWS had significant effects on the removal rate of COD,NO3-N and TN.The order of growth suitability of plants was Canna indica ＞ Verbena bonariensis ＞ Iris tectorum ＞ Acorus calamus,Canna indica and Verbena bonariensis suitably planted in bioretention in southern China due to their good pollutant removal efficiency and well-growing. |
