高级氧化技术对环境中常见毒品的降解

Degradation of Common Drugs in Environment by Advanced Oxidation Processes

简述了环境中常见毒品对人类、动植物及水生生物等造成的危害以及存在的生态风险。着重分析了过硫酸盐氧化法、光催化氧化法、超临界水氧化法、超声催化氧化法、Fenton氧化法、O_(3)氧化法以及紫外/氯(UV/chlorine)氧化法等高级氧化技术对多种毒品的降解效果和研究现状。最后总结了各方法的优缺点,并从安全、经济、节能、环保的角度出发,展望了未来毒品无害化处理技术的发展方向。

The harm and ecological risks caused by common drugs in the environment to humans,animals,plants and aquatic organisms were briefly described.The degradation effects and state-of-art of various drugs by advanced oxidation processes such as persulfate oxidation,photocatalytic oxidation,supercritical water oxidation,ultrasonic catalytic oxidation,Fenton oxidation,O_(3) oxidation and UV/chlorine oxidation were emphatically analyzed.Finally,the advantages and disadvantages of each method were summarized,and the development direction of harmless treatment processes of drugs was prospected from the perspectives of safety,economy,energy saving and environmental protection.
