Catalytic ozonation is an advanced oxidation technology which combines the strong oxidizing property of ozone with
its character of being catalyst. Catalytic ozonation has obvious advantages in the treatment of phenolic wastewater. The progress
of catalytic ozonation of phenolic wastewater at home and abroad has been systematically summarized. The merit and demerit of
different reaction systems has been discussed and some suggestions for improvement and development direction has been
pointed out in this article.
