- Abstract:
-
The effects of pH, temperature, voltage, NaCl dosage and other factors on phenol removal rate and COD removal rate were investigated by electrocatalytic oxidation. The results show that this method can effectively remove phenol and COD from wastewater, especially the two factors of voltage and Na-Cl dosage have a great influence on the removal rate of phenol and COD. Two composite electrocatalytic oxidation methods were used to treat phenol-containing wastewater, one was direct addition of H2O2, and the results showed that the phenol removal rate could reach more than 95%. The other is concentrated H2SO4, and the phenol removal rate can reach more than 90% under suitable conditions. It is concluded that the electrocatalytic oxidation method can achieve satisfactory results in the treatment of wastewater containing refractory organic matter.
