| Abstract: | The article presents the principle and reaction mechanism of the advanced oxidation process(AOP)-semiconductor photocatalytic oxidation to degrade organic pollutants in wastewater. We also summed up some methods, such as semiconductor photocatalysts modification, photocatalysts immobilization and the addition of electron scavengers or hole scavengers to improve semiconductor photocatalytic efficiency. When combining AOP with biodegradation, the treatment of wastewater will be more effective and more economical. Some of AOP applications in treating wastewater in the last two years are also presented. |
