采用Fe^(2+)/NaClO处理乐果废水的研究

Study on Treatment of Dimethoate Wastewater by Fe^(2+)/NaClO

研究了利用NaClO在酸性条件下生成的HClO代替Fenton试剂中的氧化剂H2O2,在Fe2+的作用下对乐果模拟废水进行处理。结果表明此方法处理乐果废水的效果比较明显。使用Fe2+/NaClO氧化处理乐果模拟废水,在pH值等于2,NaClO与FeSO4·7H2O的投加量分别为10mL/L,2.5g/L,振荡时间为30min,乐果初始质量浓度小于53mg/L时,乐果的处理率大于88.90%。

This study used NaClO to produce HClO in the acidic solution, replacing H2O2 in the fenton reagent to treat dimethoate wastewater with exist of Fe^2＋. The results showed that the use of Fe^2＋/NaClO in treating dimethoate wastewater can make a good effect. The best reaction conditions were settled as follows： the pH was 2, the shaking time was 30 min, the dosage of FeSO4·7H2O and NaClO were 2.5 g/Land 10 mL/L respectively. When the consistency was lower than 53 mg/L, the removal rate of dimethoate in wastewater was higher than 88.90%.
