摘　　要： 通过溶胶—凝胶方法制备了负载TiO2的颗粒活性炭(TiO2/GAC),并以亚甲基蓝染料为处理对象,研究了不同负载比例的TiO2/GAC对亚甲基蓝的吸附性能及其采用电催化再生的可行性。试验结果表明,负载TiO2能提高颗粒活性炭的电催化再生吸附能力,且负载量越高则多次再生能力越强。采用填充TiO2/GAC(0.8∶1)的固定床处理自来水,在施加电压的情况下,可显著提高TiO2/GAC去除TOC的能力。 Granular activated carbon loaded with TiO2 （TiO2/GAC） was prepared by the sol - gel process. Taking methylene blue wastewater as treatment object, the adsorption of methylene blue by TiOE/GAC at different loading ratios and the feasibility of its electro-catalytic regeneration were studied. Experimental results show that the electro-catalytic regeneration capacity is enhanced by loading TiO2 on GAC. When the greater mass is loaded, the regeneration performance is increased. A packed-bed reactor filled with TiOE/GAC at the ratio of 0.8 ： 1 can effectively remove TOC from tap water under the voltage application.
