STUDY ON PHOTOCATALYTIC DECOMPOSITION OF ORGANIC MICROPOLLUTANTS IN DRINKING WATER USING REACTOR WITH TiO2 FILM COATINGS ON GLASS TUBE SURFACE

This paper introduce briefly the mechanism of photocatalytic oxidation organic and the structure of testing reactor with TiO 2 film coatings on glass tube surface,as well as testing process of treatment organic micropollutants in the drinking water.These results show that the testing reactor could successfully oxidize prior pollutants of CHCl 3,CCl 4 and CH 2 CH Cl 3,after 1 hour treatment,the removal efficiency of these prior pollutants in the drinking water reached 95%.The reactor needs simple equipment and less investment,and operates easily and has a quite stable performance.In a word,this reactor is an ideal drinking water purification equipment and has a better commercial future.
