Landfill leachate treatment by a boron-doped diamond-based photo-electro-Fenton system integrated with biological oxidation: A toxicity, genotoxicity and by products assessment.

A photo-electro-Fenton (PEF) reactor employing boron-doped diamond (BDD) and soft iron anodes was studied in landfill leachate (LL) treatment. The reactor operation parameters (ROP) HO concentration, current intensity and flow rate were investigated in the removal of Abs 254 nm. The PEF process with BDD anode, operating at the best operational conditions, was used as a pre-treatment and enabled biological oxidation (BO).
