Abstract

Treatment of pulping wastewater by using a novel electrochemical reactor,i.e.the three phase fluidized bed electrode,reactor were invesigated.The effects of air flow rate,applied voltage,pH value and FeSO₄ concentration on electrolysis efficiency were investigated.It was clearly shown that the 20 V of voltage,0.3 m³·h^-1 of air flow rate,1000 mg L^-1 of FeSO₄ concentration and pH≈2.5 were its best conditions.COD removal could be 70.1% under these conditions.
