[Method] The alkali out pretreatment was used to investigate the effects of NaOH concentration, molar ratio of H2O2 to Fe2＋ and H202 dosage on COD removal rate and decolourization ratio. [Result] The optimal operating conditions were determined as follows： pH=3.0, NaOH concentration of 15 g/L, n [H2O2]：n [Fe2＋] =4.20, reaction time of 30 min. [Conclmio.] The research provided scientific references for the treatment of high concentration wastewater from fungicide production.展开更多
