摘　　要：为了探究非均相Fenton催化剂对实际废水的处理效果,以维生素C二级生化出水为研究对象,分别考察了针铁矿、磁铁矿和硫铁矿烧渣等含铁矿物质以及部分金属或金属氧化物的吸附性能和非均相Fenton技术的催化氧化性能.选取硫铁矿烧渣作为负载催化剂,融合CuO、Al2O3、TiO2、NiO、Cr2O3、Ag2O,利用高温微孔技术制备非均相Fenton催化剂,当H2O2、FeSO4投加量分别为6.87、4.29 mmol·L-1时,COD去除率能稳定达到70%左右.In order to evaluate the effect of heterogeneous Fenton catalyst treatment on wastewater, using the secondary effluent of Vitamin C as the target contaminant, adsorption and catalytic oxidation in heterogeneous Fenton technology of Goethite, Magnetite, Pyrite cinder and parts of metal oxides were investigated. Pyrite cinder was selected as the supported catalyst. Combined with metal oxides（ CuO, Al2 O3 , TiO2 , NiO, Cr2 O3 , Ag2 O ） , the heterogeneous Fenton catalyst was prepared through high-temperature micro-hole technology. Under the condition of H2 O2 dosage of 6？87 mmol·L-1 , FeSO4 dosage of 4. 29 mmol·L-1 , the removal rate of COD reached 70%approximately.
