摘要
活性污泥法处理污水产生的大量剩余污泥已成为大多数污水处理厂亟待解决的问题,而污泥减量就是从源头上减少污泥的产生。臭氧氧化技术是一种有潜力的清洁无二次污染的污泥减量技术。文中阐述了臭氧在污泥减量技术中的应用背景及基本原理,从不同角度分析了臭氧氧化技术的应用现状,指出了最新的研究热点以及当前存在的问题和未来可能的发展方向。
Proper disposal of excess sludge which comes from the conventional active sludge treatment for sewage water is a major technical challenge for most wastewater treatment plants. And sludge reduction is the radical way to solve the the technology of ozonation in sludge reduction is one kind of potential technologies of sludge reduction with clean, more pollution. The paper presented a review of ozonation for less sludge production, including the background, basic principle, practice in the dose of ozone, the impact of sludge nature and the combined processes of ozonation and all kinds of biological treatment employing the activated sludge process, respectively. The latest hot research off the press as well as current problems and the possible development direction in future were pointed out in the paper.
