摘  要:
在静态水培试验条件下,对不同浓度垃圾渗滤液条件下水葫芦和大薸的生长状况及其净化效果进行研究。结果表明:在高浓度(COD 3546.7mg.L-1、NH3-N 527.5mg.L-1、TP 8.02mg.L-1)垃圾渗滤液条件下(HCL)水葫芦和大漂全部被毒害致死,在中浓度(COD 1233.3mg.L-1、NH3-N 182.9mg.L-1、TP2.83mg.L-1)垃圾渗滤液条件下(MCL)生长状况差,生物量急剧减少。在低浓度(COD 660.0mg.L-1、NH3-N 99.7mg.L-1、TP 1.59mg.L-1)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。24d后水葫芦对COD、NH3-N和TP的去除率分别为85.9%,99.8%和84.8%,大薸对COD、NH3-N和TP的去除率分别为89.4%,99.1%和71.7%。试验结束后,COD与NH3-N浓度均达到《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。

摘  要:
The potential of Eichhornia crassipe and Pistia stratiotes L.to improve the water quality of landfill leachate was evaluated under the static conditions.In undiluted landfill leachate(COD 3546.7mg·L-1、NH3-N 527.5mg·L-1、TP 8.02mg·L-1),Eichhornia crassipes and Pistia stratiotes L.failed to grow.In a 1:3 dilution of landfill leachate(COD 1233.3mg·L-1,NH3-N 182.9mg·L-1,TP 2.83mg·L-1),growth of Eichhornia crassipes and Pistia stratiotes L.was inhibited and the biomass declined dramatically.In a 1:5 dilution of landfill leachate(COD 660.0mg·L-1,NH3-N 99.7mg·L-1,TP 1.59mg·L-1),Eichhornia crassipes and Pistia stratiotes L.grew successfully.After 24d,the removal efficiencies of Eichhornia crassipes to COD,NH3-N and TP were 85.9%,99.8% and 84.8%,respectively.The removal efficiencies of Pistia stratiotes L.to COD,NH3-N and TP were 89.4%,99.1% and 71.7%,respectively.Eventually the COD and NH3-N in the water meet the discharging standard of "Life Landfill Pollution Control Standards"(GB16889-2008),the TP reach Ⅳ class discharging standard of "Environmental Quality Standards for Surface Water"(GB 3838-2002).
