摘要
污泥无害化、减量化、资源化是当今污泥处理的主题,但污泥含水率过高的问题制约着污泥处理技术的发展。介绍了真空脱水、压滤脱水、离心脱水、造粒脱水等几种污泥脱水的机械方法,试图为机械污泥脱水技术的实际应用提供参考。
Harmless treatment,reduction and recycling of excess sludge were the theme of sludge treatment nowadays.However,the development of sludge treatment technology was restricted by the high moisture content of excess sludge.Introduced several mechanical sludge dewatering methods,including vacuum dewatering technology,pressure filtration dewatering technology,centrifugal dewatering technology and granulation dewatering technology.This study tried to provide a reference for the practical application of mechanical sludge dewatering technology.
