污泥回用技术研究进展

Approaches to the Research on Sludge Reuse Technology

目前常规的活性污泥处理的方法都存在投资大、处理成本高等各种问题,本文介绍了剩余污泥可溶化回流氧化处理技术及其尚待改进的问题,并重点列举了臭氧、超声波法处理剩余污泥工艺的应用实例和研究现状。为达到污泥零排放的目的并能从本质上减少污泥排放量提出了未来的发展方向和研究方向。

In view of the disadvantages in conventional activated sludge process such as the high investment and operational costs,some new methods on sludge disintegration techniques without excess sludge production are introduced. The current status of the practice and applications on ozone and ultrasonic sludge treatment should be paid attention to. The research trend is favorable to sludge elimination and reducing surrounding pollution.
