五种水培观赏植物对城市污水净化效果的研究

The Research of Purification Effect about Five Hydroponic Ornamental Plants in Polluted Water

本研究以鸢尾(Iris tectorum)、绿萝(Scindapsus aureun)、常春藤(Hedera nepalensis K,Koch var.sin ensis(Tobl.)Rehd)、吊兰(Chlorophytum)、麦冬(O.japonicus(L.f.)Ker-Gawl.)5种观赏植物为试材,水培驯化后放入取定的污水中,比较各植物对污水的净化效果。试验结果表明,各植物处理组均表现了较强净化效果,其中:鸢尾对污水总氮去除效果最好,去除率为56.43%;绿萝除总磷效果较好,为41.80%;麦冬和绿萝对EC值降低较好,分别下降31.59%、31.83%;各植物组铵态氮去除效果也较对照组显著。

This study with Iris （Iris tectorum）, Epipremnum Aureum（Scindapsus aureun）, Ivy Hedera nepalensis K Koch vat. Sin ensis （Tobl.） Rehd）, Bracketplant （Chlorophytum）, Dwarf lilyturf （O. japonicus（L, f. ）Ker--Gawl. ） five kinds of ornamental plants as materials, using hydroponics domestication approach in the floating bed m sewage, after determine the indicators of sewage before and after the change to compare various plants for water purification effect. Test results show that the plant treatment group showed better purification effect, including： iris total nitrogen removal efficiency of wastewater, the best removal rate is 56.43%; Money plant total phosphorus removal effect is good, is 41.80%; Reeds and other on EC value lower, fell by 31.59%, 31.59% respectively; Different plant groups of ammonium nitrogen removal efficiency than the control group significantly.
