铁屑过滤-光催化氧化处理染料废水

Treatment of Dye Wastewater with Iron Chips Filtration-photocatalytic Degradation Process

探讨了采用铁屑过滤-光催化氧化法处理印染废水和合成染料废水的工艺,与单独用铁屑过滤法和光催化氧化法进行比较,结果表明将两者联合使用效果较好,对印染废水和染料废水的脱色率分别达91%、85%,对COD的去除率也分别达73%和44%。

The treatment of dye wastewater and synthetic dye wastewater with iron filtration-photocatalytic degradation process was investigated.Comparing with single iron chips filtration or photocatalytic degradation process,the results showed that the efficiency of combined process was higher.The decolorizing efficiencies of dye wastewater and synthetic dye wastewater was 91% and 85% respectively,furthermore,COD removal efficiencies was 73% and 44% respectively.
