水培植物对农家乐餐饮废水的净化效果研究

Purification Effect of Hydroponic Plants on Agritainment Restaurant Wastewater

[目的]为农家乐废水污染的水体实施生态修复提供研究基础.[方法]以农家乐餐饮废水为净化对象,选取春羽、鹅掌柴、虎皮兰和绿萝这4种常见水培植物进行废水净化效果试验.[结果]春羽、鹅掌柴、虎皮兰和绿萝对农家乐餐饮废水均具有较好的净化能力,对CODCr的去除率为48.5％ ～ 77.7％,TP的去除率达91.2％,NH4＋-N的去除率达89.8％,均优于对照处理.[结论]春羽、虎皮兰对农家乐餐饮废水具有良好的耐污能力和适应性.

[ Objective ] The research aimed to provide study basis for the ecology recovery of water body polluted by the wastewater from agritainment. [ Method] Wastewater purification effect experiment taking agritainment restaurant wastewater as purifying object was carried out using four common hydroponic plants such as Philodenron selloum, Schefflera octophylla, Sansevieria trifasciata, Scindapsus aureum. [ Result] The results showed that P. selloum, S. octophylla, S. trifasciata, S. aureus had better purification ability on agritainment restaurant wastewater than the control treatment, with CODcr removal rate of 48.5% - 77.7% , TP removal rate of 91.2% , NH4^＋-N removal rate of 89.8%. [ Conclusion] P. seUoum and S. trifasciata had significant pollution resistibility and adaptability to agritainment restaurant wastewater.
