我国超声波处理污泥技术的研究进展

The Research of Ultrasonic Waves in Sludge Treatment in China

针对我国污水处理厂日趋增多,污泥产量大,处理费用高,污泥处置存在很多问题,阐述了污泥减量化的重要性。超声波处理污泥技术具有污泥减量效果好而且无污染的特点,同时对提高污泥活性,促进污泥消化、脱水以及用于处理污泥的联合效应中也有很好的效果,同时提出了超声波技术处理污泥存在的问题。

This paper deals with the application of ultrasonic waves in sludge treatment. Ultrasonic waves reduce the sludge quantity of the WWTP. The technology of ultrasonic waves in sludge treatment can improve the OUR of sewage sludge, accelerate the digestion of sewage sludge and make sludge dewater. While the technology of ultrasonic waves in sludge treatment have some problems to solve.
