摘要： 以沥青废水为处理对象，对采用超声、催化、掺杂的方式强化铁炭微电解进行研究，以期提高COD去除率。结果表明：单纯使用微电解技术，沥青废水的COD去除率为63%，使用超声、催化剂MnO₂、掺Cu、掺Al等手段对铁炭微电解进行强化后，废水的COD去除率分别为78.3%、76.5%、75.9%、82%，对比发现Fe-Al-C微电解是其中最为简单有效的强化铁炭微电解工艺，因此对Fe-Al-C微电解进行了反应动力学分析。

Abstract: Aiming at the research object,asphalt wastewater,the intensified ferric-carbon microelectrolysis has been studied by ultrasonic,catalysis,and doping methods,so as to improve the removing rate of COD. The results show that if only ferric-carbon microelectrolysis technique is used,the COD removing rate of asphalt wastewater is 63%. If ultrasound,catalyst MnO₂,Fe-Cu-C microelectrolysis and Fe-Al-C microelectrolysis are used for intensification,the COD removing rates of the wastewater are 78.3%,76.5%,75.9% and 82%,respectively. It is found that by comparison,Fe-Al-C microelectrolysis is the simplest and most effective way to make intensification. Therefore,Fe-Al-C microelectrolysis is analyzed by reaction dynamics.

Key words: ferric-carbon microelectrolysis, intensification, asphalt wastewater, COD removal, reaction kinetics analysis
