Abstract
Choosing humic acid as a typical natural organic matters (NOM), efficiency of heterogeneous catalytic ozonation on THMFP was studied. The results show that, in the presence of solid catalyst, the mineralization of ozone on NOM was enhanced. While the biodegradability in catalytic ozonation process did not enhanced compared with ozonation. In the test, the efficiency of catalytic ozonation on the removal of THMFP had obvious advantage on ozone oxidation alone in the initial five minutes and the last 20 minutes, in 5～20 minutes, there was no THMFP degradation difference between catalytic ozonation and ozonation alone. By comparing THMFP/TOC, it was suggested that the active sites in organic was decreased after catalytic ozonation and ozone oxidation, and the catalytic ozonation was more effective than ozonation alone.
