Study on the Purification Effect of Ruellia brittoniana on Wastewater and Its Practical Application

研究了翠芦莉Ruellia brittoniana对污水的净化效果,结果表明,翠芦莉对污水中的化学需氧量(COD)、总磷(TP)、总氮(TN)和氨氮(NH4-N)都有较好的去除效果,但植株大小对其去除效果没有显著差异。在华南地区已有多个生态园林项目应用翠芦莉作为生态修复污水净化植物品种,如梅州市芹洋半岛滨水湿地公园、中山市火炬开发区得能湖公园、贵州云漫湖等项目中,在生境较为恶劣的区域采用翠芦莉作绿植设计,经过一段时间追踪观察可知翠芦莉对生境修复效果明显。

Abstract: The purification effect of Ruellia brittoniana on wastewater was studied. The results showed that R. brittoniana had better removal effect on both COD, TP, TN and NH4-N in wastewater, but there was no significant difference in the removal efficiency of plant size. There have been many ecological garden projects in South China where R. brittoniana has been used as a plant variety for ecological restoration of wastewater purification. For example, KiunYong Peninsula Wetland Park in Meizhou, the Deneng Lake Park in Zhongshan City Torch Development Zone, and the Yunman Lake in Guizhou, the green planting design of R. brittoniana has been adopted in the region where the habitat was relatively bad. After a period of followup observation, the effect of R. brittoniana on habitat restoration was obvious.
