Advanced Treatment of Biochemical Effluent from Landfill Leachate by Fenton and Ozone
The Fenton-ozone advanced oxidation process was used to treat the landfill leachate nanofiltration membrane concentrate,and the optimal operation mode and parameters of each process section were screened.Under the optimal conditions,COD could be removed from 2 000 mg·L-1 to less than 60 mg·L-1,meeting the discharge standard in Table 2 of the"Standard for Pollution Control on the Landfill Site of Municipal Solid Waste"(GB16889-2008).
