高级氧化技术在炼厂废水深度处理中的应用

The Application of Advanced Oxidation Technology in the Refinery Wastewater Advanced Treatment

高级氧化技术(Advanced oxidation processes,AOPs)是通过各种光、声、电、磁等物理化学过程产生大量活性极强的自由基(如·OH),利用这些活性强的自由基氧化水中的污染物以达到处理废水目的一种技术。高级氧化技术分:臭氧氧化法、光化学氧化法和光催化氧化法、Fenton法和类Fenton法、湿式氧化法和湿式催化氧化法、电化学氧化法、超临界水氧化法及超临界水催化氧化法等。通过介绍高级氧化技术在炼厂废水的处理中的进展,以及对各种方法的比较与评价,对今后高级氧化法在炼厂废水的应用和发展提出了合理性的建议与展望。

Advanced Oxidation Technology （Advanced oxidation processes, AOPs） could produce a large amotmt of highly reactive free radicals （such as ·OH） through a variety of light, sound, electricity, magnetism, and other physical and chemical processes, and the use of these active contamination strong free radical oxidation in water a technique was reached wastewater treatment purposes. Advanced Oxidation Technology is divided into a good variety： ozone oxidation and photochemical oxidation and light catalytic oxidation method, Fenton method and class Fenton method, wet oxidation method and wet catalytic oxidation, electrochemical oxidation, supercritical water oxidation and catalytic supercritical water oxidation method, etc. Through the introduction of advanced oxidation technology in refinery wastewater treatment progress, as well as to the comparison and evaluation of various methods, we put forward reasonable Suggestions and outlook in the future.
