中文摘要：

通过溶胶一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。

英文摘要：

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.
