摘要
用Fenton试剂处理丁苯橡胶废水,考察了H2O2和FeSO4的用量、初始pH值、反应时间以及反应温度对废水化学需氧量(COD)去除率的影响。结果表明,适宜的处理条件为H2O2(以1 L废水计)8 mL、FeSO4质量浓度1.0 g/L、初始pH值3～10、反应时间30 min、反应温度40℃,在此条件下废水COD的去除率可超过55%。
Fenton reagent method was used to treat wastewater from styrene-butadiene rubber（SBR） production,and effects of the amount of H2O2 and FeSO4,initial pH value,reaction time and temperature on the removal rate of chemical oxygen demand（COD） were investigated.The results showed that the optimal operating conditions were as follows： H2O2 8 mL（based on 1 L wastewater）,FeSO4 1.0 g/L,initial pH value 3-10,reaction time 30 min and reaction temperature 40 ℃,under above conditions the removal rate of COD was over 55%.
