摘要：
超声降解水体中有机污染物是近年来兴起的一项极具发展前景的新型水处理技术。在超声作用下,液体产生超声空化效应,可有效降解水中一些难降解大分子有机物。利用超声技术 (US)及超声与组合高级氧化技术(AOPs),例如US -H2O2,US -H2O2-FeSO4 对造纸废水进行处理。试验结果表明 :此技术可一定程度降解造纸废水中大分子有机物,造纸废水的CODCr及TOC均有一定程度降低。有望成为生化法处理造纸废水的前处理技术

Abstract:
Ultrasonic based chemical reaction systems are emerging as promising alternatives for the removal of macromolecular organisms in wastewater. Because of the function of ultrasonic wave, the effect of ultrasonic cavitation can be produced , meanwhile, the macromolecules organisms are removed. The paper mill wastewater is treated by US and the combination of advanced oxidation process(AOPs) such as US- H2O2, US- H2O2- FeSO4.The results show the destructional removal of organic compound is effective.The concentration of CODCr and TOC are decreased. It will be possibly become the pre-treatment of biodegradat ion technology.
