摘要
超声技术作为一种新型的氧化方法,能提高难降解有机物的降解率和增强水处理中的可生化性,在焦化废水处理中已经发挥了一定的作用并有广阔的发展前景。介绍了焦化废水的性质及成分以及超声空化降解难生物降解有机废水的机理和主要影响因素对降解焦化废水中污染物的影响及其机理,并综述了超声技术在焦化废水处理中的应用与研究进展。
Ultrasonic technology has played a great role, and will find a promising future in the area of wastewater treatment as one of the advanced oxidation methods owing to increasing degradation of nondegradable organic pollu-tants and enhancing biology activity in wastewater treatment. This paper introduces the mechanisms and such main effecting factors of degradation pollutant,and then summarized the recent adbance of application and research of ultrasonic technology in wastewater treatment.
