超声波-紫外光氧化处理有机废水技术综述

Technical review on oxidation degradation organic pollutants in wastewater by ultrasound in the presence of ultraviolet

论述了超声波 (US)降解有机污染物技术的原理和效果 ,以及国内外现状与发展趋势 ,指出超声波的“空化”作用是其主要的作用机制 ,超声波与其他作用如紫外光辐射、催化氧化等联合运用 ,可大大加速和提高有机污染物的矿化度 ,在处理难降解有机污染物和有毒有害有机污染物方面 ,特别是在净化环境。

The technology of degradation organic pollutants by ultrasound is described,including its principle ,effect and development at home and abroad.The interaction mechanism is based on the cavitation .Ultrasound technology ,combined with ultraviolet,catalysis and oxidation,can greatly increase the mineralization degree of organic pollutants ,and it has enormous application advance on degradation of unbiodegradable,toxic and hazardous organic pollutants,especially on environmental priority ones.
