Application of Heterogeneous Catalytic Ozonation in Wastewater Treatment: An Overview

Catalytic ozonation is a non-selective mineralization technology of organic matter in water by using active free radicals generated ozone degradation. can be divided into homogeneous catalytic reactions metal ions as catalysts and heterogeneous solid catalysts. Homogeneous has many problems, such low rate, secondary pollution caused the introduction utilization efficiency oxidants, which limit its practical application. Compared with technology, advantages easy recovery, lower cost treatment, higher activity improved rate matter. This overview classifies describes for including different types oxides, metal-free catalysts, substrates used to immobilize In addition, process involved multiphase complex reaction discussed. The effects parameters on performance are also
