摘要: 针对工业废水中难以去除的络合态重金属,采用自制的负载型FeSO4/HS为催化剂,用Fenton-like氧化2,3-二羟基琥珀酸铜废水,并将游离出来的铜加碱沉淀除去。研究发现,当22O2为25 mmol/L时负载型FeSO4/HS催化的催化活性最高。当H2O2分3次等量投加时获得最高COD和铜去除率。催化剂的活性随降解次数的增加而缓慢下降,可以通过补加亚铁的方法消除,亚铁补加量在0.4 mg/L时效果最好,补加后催化剂的催化活性具有较好的持续性。

Abstract: Wastewater containing 2, 3-dihydroxy succinic acid copper was pre-treated by Fenton-like oxidation using self-made supported FeSO4/HS as the catalyst, and the released free cupric ions were removed by alkali precipitation. The results showed that supported FeSO4/HS catalyst had the highest catalytic activity when the value of pH was in the range of 2～3 and H2O2 dosage was 25 mmol/L. The highest removal efficiency of COD and copper could be reached while the H2O2 dosage was added averagely for three times. The catalytic activity decreased gradually with the increase of degradation times, which could be eliminated by the addition of Ferrous ions. The catalyst showed the best sustainability of catalytic activity when the addition of Ferrous ions was at the dosage of 0.4 mg/L.
