为了探究底栖藻类和沉水植物（苦草）对猪粪废水的处理效果，及苦草恢复重建的环境条件，通过设置不同浓度的猪粪废水处理，进行了为期32 d的室内模拟实验。结果表明：底栖藻类、苦草、底栖藻类-苦草处理组对高浓度猪粪废水的COD和氮、磷均存在显著的去除效果；COD的最大去除率均大于86%，底栖藻类-苦草混合培养对高、中浓度猪粪废水中磷、氮的平均去除率分别大于62%和70%，高于二者单独培养的处理组（均小于59%和65%）。实验期间，底栖藻类、苦草和浮游藻类Chla含量的变化以及苦草的CAT、MDA含量变化表明，高浓度的猪粪废水会对苦草产生短期的逆境胁迫，但底栖藻类的存在可以减缓高浓度氮磷对苦草的胁迫效应，在中浓度氮磷且有底栖藻类存在的条件下，有利于苦草的恢复重建。

Water plants are often used to remove nutrients from wastewater. This research was conducted to assess the efficiency of nutrient removal from swine wastewater using biological treatment system in a laboratory-scale experiment with periphyton and submerged macro-phyte-V allisneria natan during 32 days. The systems included high, medium and low concentrations of nutrients in wastewater. The maxi-mum removal rates of chemical oxygen demand(COD)were more than 86%at high concentrations. The average phosphorus(P)and nitro-gen(N)removal rates were respectively over 62%and 70%for both high and medium concentrations in mixed nutrient systems, greater than in single nutrient systems(59%and 65%). Changes of physiological activities showed that V . natan suffered a short-term stress at high nu-trient concentrations. However, such stresses could be alleviated by the presence of periphyton. In conclusion, the optimum condition for V . natan would be medium concentrations of nutrients with periphyton.
