Research on the combined process and its application of environmental control technology and photocatalytic
The photocatalytic oxidation technology which has the advantages of mild reaction conditions and no sec-ondary pollution has been considered to be a new type of water treatment technology. However ,there exist some defects in practical application,such as low efficiency and difficult to recover,while the combination of photocata-lytic technology and other environmental control technologies can solve these problems. Researches on the com-bined processes of photocatalytic oxidation technology and traditional environment control technologies(membrane separation,oxidation,biological method),the other advanced oxidation technologies(ultrasound,electrochemis-try,Fenton),as well as the other environmental technologies,for treating various wastewater are discussed. In ad-dition,their reaction mechanisms and application are summarized.
