Treatment of landfill leachate by combined electro-fenton oxidation and sequencing batch reactor method

Treatment of landfill leachate by combined electro-fenton oxidation and sequencing batch reactor method

Water Research 34(17): 4243-4249, December

Treatment of old-aged landfill leachate by combined chemical and biological methods was investigated in the present study. The electro-Fenton method assisted by chemical coagulation was employed and found to be highly efficient in removing a large amount of refractory organic and inorganic compounds in the leachate. The sequencing batch reactor (SBR) was capable of further elevating the water quality of leachate effluent to the discharge or non-potable reuse standard. Optimum operating conditions for each treatment unit were identified to offer a good overall performance of the combined treatment system that was found to provide an efficient and economic alternative for dealing with the landfill leachate.
