摘要: 在静态水培实验条件下，对不同浓度垃圾渗滤液条件下凤眼莲的生长状况及其净化效果进行了研究。结果表明，在高浓度（COD 3 546.7 mg/L、NH3-N 527.5 mg/L、TP 8.02 mg/L）垃圾渗滤液条件下（HCL）凤眼莲全部被毒害致死，在中浓度（COD 1 233.3 mg/L、NH3-N 182.9 mg/L、TP 2.83 mg/L）垃圾渗滤液条件下（MCL）生长状况差，生物量减少为实验前的32.6%。在低浓度（COD 660.0 mg/L、NH3-N 99.7 mg/L、TP 1.59 mg/L）垃圾渗滤液条件下（LCL）能够正常生长，且对低浓度垃圾渗滤液有较好的净化效果。24 d后COD、NH3-N和TP的去除率分别为85.9%，99.8%和84.8%。COD与NH3-N均达到《生活垃圾填埋场污染控制标准(GB16889-2008)》排放标准，TP达到《地表水环境质量标准(GB 3838-2002)》Ⅳ类排放标准。

Abstract: The potential of Eichhornia crassipes to improve the water quality of landfill leachate was evaluated under the static conditions. In undiluted landfill leachate (COD 3 546.7 mg/L、NH3-N 527.5 mg/L、TP 8.02 mg/L)， Eichhornia crassipes failed to grow. In a 1∶3 dilution of landfill leachate (COD 1 233.3 mg/L， NH3-N 182.9 mg/L， TP 2.83 mg/L)， growth of Eichhornia crassipes was inhibited and the biomass reduced to 32.6%. In a 1∶5 dilution of landfill leachate (COD 660.0 mg/L， NH3-N 99.7 mg/L， TP 1.59 mg/L)， Eichhornia crassipes grew successfully. In terms of reductions in nutrients， chemical oxygen demand (COD)， Eichhornia crassipes had a better purification effect in 1∶5 dilution of landfill leachate. COD was reduced by 85.86%， NH3-N by 99.38% and TP by 84.76% in 24 day batch growth. Eventually the COD and NH3-N in the water meet the discharging standard of Life Landfill Pollution Control Standards (GB16889-2008)， the TP reach fifth class discharging standard of Environmental Quality Standards for Surface Water (GB 3838-2002).
