摘　　要：运用次氯酸钠氧化法对碱性棕G模拟废水进行处理。试验研究了碱性棕G初始质量浓度、次氯酸钠投加体积、搅拌时间对碱性棕G脱色率及COD去除率的影响。试验结果表明,在碱性棕G质量浓度为40 mg/L的条件下,次氯酸钠投加体积0.4 mL,搅拌时间控制为4.5 h,碱性棕G的脱色率可达86.11%,COD去除率可达84.18%。Wastewater containing alkaline brown G was treated through the sodium hypochlorite.The influence of sodium hypochlorite dosage,the reaction time and the initial concentration of alkaline brown G were investigated.Under the optimal condition which the initial concentration of alkaline brown G was 40 mg/L,the sodium hypochlorite dosage was 0.4 mL and the reaction time was 4.5 h,the decoloration rate was 86.11%and the COD removal rate was 84.18%.
