常温电催化非均相催化氧化技术在污水处理中的应用

Application of Heterogeneous Electrocatalytic Oxidation Technology at Room Temperature in Wastewater Treatment

为考察一种新型电催化氧化技术对有机染料的降解效果,在低压电场下,利用廉价金属制备的多孔陶粒催化剂电催化处理甲基橙、苋菜红及亚甲基蓝有机染料模拟废水。此外,还进行了电催化降解土霉素的实验。结果表明,电催化氧化新型废水处理技术对难以降解的有机物具有不错的处理能力,可以作为高毒难降解有机污水的预处理或者深度处理手段。

A new type of ceramic particulate catalyst was produced using cheap metals,and under low voltage electric condition the catalysts show great catalytic degradation abilities,simulated dye wastewater such as methyl orange,amaranth,and methylene blue were degraded in less than one hour.Furthermore,the electric catalytic degradation of terramycin was also investigated.In general,this new kind of catalyst has excellent electric catalytic degradation ability treating organic wastewater.It can be developed as a very promising pre-treatment or deep processing path in industrial wastewater treatment.
