摘要
超声技术作为一种新型水处理方法,主要是利用超声过程中的高温热解和自由基氧化污染物。影响超声技术作用效果的因素主要有两类,一类是超声波的使用参数:频率、功率和声强等;另一类是待处理废水的物化参数:温度、微粒及污染物性质等。综述了这些主要因素作用规律的研究进展,并基于水处理科学与工程发展趋势,提供了值得深入研究的问题。
As a new water treatment method, ultrasound technology is mainly based on high temperature pyrogenation and free radical oxidation contaminant during ultrasound process. There are two main factors in ultrasound technology： one is the parameters of ultrasound, such as frequency, power and so on. The other is wastewater＇s physic-chemical parameters,such as temperature, the character of particle and contaminant. The key factors research advance of key factors was summarized and some important problems were displayed, which based on developing trend of water treatment science and engineering.
