非均相芬顿催化剂法处理氨肟化废水的研究

Study on treatment of ammoximation wastewater by heterogeneous fenton reaction catalytic method

将亚铁盐和多种金属盐负载在陶粒上制成非均相芬顿催化剂,该催化剂与传统芬顿试剂共同作用降解含有大量有机物的氨肟化废水,该催化剂的使用可使双氧水投加量降低14.7%,亚铁盐投加量降低60%,大大减少了污泥的产生量,并能显著提高对污水COD的去除效果。

Make ceramsiteimmobilized Fe2+ and Polymetallic salts into Heterogeneous Catalyst for Fenton Reaction. The catalyst cooperates with the traditional Fenton reagent to degrade the ammoximation wastewater containing a large amount of organic matter, can reduce the dosage of hydrogen peroxide by 14.7%, the dosage of ferrous salt by 60%, and greatly reduce the sludge production. Quantity, it can significantly improve the removal effect of sewage COD.
