摘　　要：Early research mainly studies the performance of TiO2 power condition.As a result of using power condition TiO2,its power is slight,not easy to precipitate,and creates another pollutants.Therefore,the ceramic granulated substance carrier material was used to prepare the TiO2 thin film to carry on the water treatment to obtain the good effect.The gangue of coal was used to make the ceramic granulated substance basis,then in a ceramic granulated basis place TiO2 thin film was painted,advancing together the running water processing experiment.The test result is as follows:The TOC content reduces by above 80%,and used to filter the material to be possible to replace at will,which has obtained good effect.In the testing,using the scanning electron microscope analyzer,carrying on the superficial appearance view to the TiO2 ceramic sand leach material to scratch,finally indicated,it has some turtle crack in the TiO2 ceramic granulated substance surface,has crystal boundary surface flaw,causes it to have bigger catalytic activity.Early research mainly studies the performance of TiO2 power condition.As a result of using power condition TiO2,its power is slight,not easy to precipitate,and creates another pollutants.Therefore,the ceramic granulated substance carrier material was used to prepare the TiO2 thin film to carry on the water treatment to obtain the good effect.The gangue of coal was used to make the ceramic granulated substance basis,then in a ceramic granulated basis place TiO2 thin film was painted,advancing together the running water processing experiment.The test result is as follows:The TOC content reduces by above 80%,and used to filter the material to be possible to replace at will,which has obtained good effect.In the testing,using the scanning electron microscope analyzer,carrying on the superficial appearance view to the TiO2 ceramic sand leach material to scratch,finally indicated,it has some turtle crack in the TiO2 ceramic granulated substance surface,has crystal boundary surface flaw,causes it to have bigger catalytic activity.
