含油废水处理方法研究进展

Progress of oily wastewater treatment

概述了含油废水的特征,对比分析了气浮法、絮凝法、膜分离法、生物法等处理含油废水的方法及其相应的优势和不足。重点评述了几种处理含油废水的新方法(如电化学法等)及几种联合工艺的特性,对电催化技术用于处理含油废水的研究进展及应用前景作出预测。最后分析了电催化法等高级氧化技术处理含油废水的潜力,指出电催化法处理含油废水的工业应用尚需要解决的关键问题。

The characteristics of oily wastewater are reviewed. Some routine treatments for oily wastewater, such as air-floating method, flocculation method, electrolytic method, membrane separation method, biologic method, etc. are presented and their advantages and shortcomings are discussed. At the same time new treatments for oily wastewater, such as electro-catalysis and combination technologies are introduced. The progress and application prospect of electro-catalysis are emphasized. Finally the merits of electro-catalysis for the disposal of oily wastewater are analyzed and the problems to be resolved for industrial application of electro-catalysis for the disposal of oily wastewater are pointed out.
