摘要: 油污水具有污染物结构复杂、毒性高、难降解的特点,常规的以生物降解为主的处理方法难以达到理想的处理效果。新兴的光催化技术,通过改性和负载的手段,能够利用太阳光降解油污,是一种高效、经济、环境友好的含油污水处理方法。以近期文献为基础详细介绍了光催化降解含油污水的作用机理和影响因素,总结了提高不同光催化材料用于含油污水处理性能的改性和负载方法,分析并讨论了光催化降解含油污水的研发现状以及存在的不足及面临的挑战。

Abstract: Oily sewage has the characteristics such as complicate pollutant structures, high toxicity and difficult to degrade. Conventional biodegradation-based treatment methods are difficult to achieve the desired treatment effect. Emerging photocatalytic technology, which is capable of utilizing sunlight to degrade oil by means of modification and loading, is a highly efficient, economic, and environmental-friendly oily wastewater treatment technology. Based on recent literatures, the mechanism and influencing factors of photocatalytic degradation of oily wastewater are introduced. The modification and loading methods for improving the performance of different photocatalytic materials for oily wastewater treatment are summarized. The status quo of photocatalytic degradation of oily wastewater and the existing shortcomings and challenges are analyzed and discussed.

Key words: oily wastewater, photocatalysis, modification, catalyst support, degradation rate
