Study on the Advanced Treatment of Dyeing Wastewater by Photocatalytic-H₂O₂

Abstract:

The composition of dyeing wastewater is complicated, after biochemical treatment, the effluent COD is still unable to meet the emission standard. To achieve discharge standard that often require advanced treatment after biochemical. This paper investigated effect of pH, reaction time, ZnO dosage, dosage of H₂O₂ on the effect of dyeing wastewater treatment by photocatalytic-H₂O₂, the results showed that the reaction time of 15 min, pH of 4, dosage of ZnO was 4 g/L, 30% H₂O₂ dosage was 1 ml/L, the COD removal rate was highest, can reach more than 55%.
