The degradation of the CODCr of the secondary effluent water from refinery by electrocatalytic oxidation method has been studied with the purpose of reusing the secondary effluent water from refineries. The experimental results indicated that electrocatalytic oxidation method can be used for degrading CODCr in reusing the secondary effluent water from refineries. When the ρ(CODCr) of the waste water is below 30 mg/L after treatment, the electric energy consumption for the treatment of one ton of the waste w...
