[Objective] The study aimed to investigate the comprehensive effect of digesting the organic dyeing wastewater by the two methods of photocatalytic oxidation and internal electrolysis. [Method] With the dyeing wastewater of reactive brilliant blue X-BR as the researched material, the action mechanism for effecting the homogeneous photochemical catalysis in treating dyeing wastewater when CuSO4, FeCl3, KMnO4 and NaClO were taken as the photocatalyst was discussed to seek for the optimum photocatalyst and then it was combined with the internal electrolysis of scrap iron for treating application and the optimum test condition was confirmed. [Result] The combined treatment by homogeneous photochemical catalysis and internal electrolysis could make the CODCr removal rate over 83% and discoloration rate up to 85%. The optimum test condition was follows: the optimum photocatalyst was CuSO4, the optimum dosage of photocatalyst was 50 ml, 0.023 3 g copper sulfate was added into the dyeing wastewater, the photocatalytic time was 5 h, the optimum initial pH value in the liquor was 5.1-5.6, the optimum time of internal electrolysis was 3 h. [Conclusion] The photocatalytic oxidation had high CODCr removal rate and internal electrolysis had better color removal rate, so the combined application by 2 methods could get optimum effect of treating organic dyeing wastewater.
