Pilot study on heterogeneous catalyzed oxidation for micro-polluted drinking water treatment
臭氧多相催化氧化处理微污染水中试研究

A comparative pilot study of ozonation and ozone catalytic oxidation in the presnece of a novel catalyst was conducted for purification of polluted water. It was demonstrated that both ozonation and catalytic ozonation could remove UV_ 254 to the similar extent. However, catalytic ozonation has obvious advantage over the conventional ozonation in controlling COD_ Mn and TOC so as to reduce the quantity of organic compounds to transfer into the next treatment process. The catalyst could both strengthen ozonation to degrade some stable micro-organic pollutants and convert NH _ 4 -N to NO-_ 3 -N as well as enhance the mass transfer rate of ozone into water.
