Catalytic Ozonation of Raw Water from Songhua River with Nano TiO2 Supported by Zeolite
In the present paper, nanosized TiO2 supported by zeolite was used in the ozonation of Songhua River as catalyst The catalytic activity of TiO2/Zeolite for ozonation was testified by nitrobenzene removal, which is one kind of representatively resistant organic contaminant. And the removal of some organic and inorganic compounds existing in the Songhua River by Ti02/Zeolite catalyzed ozonation was investigated. GC-MS analysis showed that the Songhua River was obviously polluted by organic contaminants. Catalytic ozonation can remove about 30 kinds of organic matters from water and reduce the total organic peak area of feed water by 62.5％.
