Comparative Research on the Purification Ability in Landfill leachate by Eichhornia crassipe and Pistia stratiotes L.
摘要
Abstract
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 Standard."(GB16889-2008), the TP reach IV class discharging standard of "Environmental Quality Standards for Surface Water" (GB 3838-2002).关键词
