为探讨超声对渗滤液中有机物的影响，采用超声波处理垃圾渗滤液，发现超声频率，初始pH值，辅助曝气，反应温度和渗滤液初始浓度都有限地影响渗滤液COD的去除率。对UV－Vis扫描光谱和特定波长比值进行分析，认为· OH与芳香性物质反应，优先与羰基、羧基、羟基、酯类等基团，之后与以脂肪链为主的基团反应，最后参与芳香环的破坏。

The waste leachate was treated by ultrasound to investigate the variation of organic compounds .The re-sults showed that the ultrasonic time , ultrasonic frequency , initial pH and aeration affect removal of COD .The a-nalysis of UV-Vis spectra and changes of special wavelength ratio of leachate during ultrasonic treatment showed that · OH reacts preferentially with the aromatic materials containing carbonyl , carboxyl , hydroxyl , esters and other groups , and then with subsistent group of fatty chain , finally with aromatic ring .
