摘　　要：采用次氯酸钠对甲基橙模拟废水进行处理,研究了次氯酸钠用量、搅拌时间等对甲基橙脱色率及COD去除率的影响。处理浓度为40 mg/L的甲基橙废水,在次氯酸钠用量10 mL/L,搅拌时间3.5 h的条件下,甲基橙的脱色率可达到95%,COD去除率可达53%。Wastewater containing methyl orange was treated through the sodium hypochlorite.The influence of sodium hypochlorite dosage,the reaction time and the initial concentration of methyl orange were investigated.Under the optimal condition which the initial concentration of methyl orange was 40 mg/L,the sodium hypochlorite dosage was 10 mL/L and the reaction time was 3.5 h,the decoloration rate was 95% and the COD removal rate was 53%.
