次氯酸钠处理酸性玫瑰红B废水研究

Experimental study on methyl orange-containing wastewater treatment by sodium hypochlorite

对目标物质酸性玫瑰红B废水运用次氯酸钠进行氧化处理。研究了酸性玫瑰红B初始含量、搅拌时间和次氯酸钠用量对酸性玫瑰红B脱色率及COD去除率的影响。结果表明,酸性玫瑰红B浓度40mg/L时,在次氯酸钠用量1.0mL,搅拌时间4h的条件下,酸性玫瑰红B的脱色率可达61.02%,COD去除率可达36.78%。

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 1.0 mL and the reaction time was 4 h,the decoloration rate was 61.02% and the COD removal rate was 36.78%.
