Abstract:
A method for treating wastewater containing chemical oxygen demand (COD) by electrolysis and oxidation, comprising the steps of:(a) feeding the wastewater, iron compounds, and a suitable particulate carrier to an electrolyzing/oxidizing reactor wherein said reactor comprises a dimensionally stable Ti anode (DSA) and a cathode;(b) controlling the pH of the wastewater to less than 2.5 and initiating a fluidized bed of said particulate carrier;(c) electrolyzing and oxidizing the wastewater while continuously adding hydrogen peroxide to said reactor to remove said COD; and(d) adjusting the pH of the wastewater to 6-9 and removing the thus-treated wastewater as effluent from said reactor.
