摘　　要：随着我国经济的日益发展,每年产生大量活性污泥需要脱水处理,但是传统污泥脱水处理难以达到我国对污泥处置相关标准的要求,因此急需探究污泥深度脱水新工艺以适应我国经济发展要求,基于此,总结了近年来污泥深度脱水新工艺——电化学脱水技术,对其脱水原理、脱水影响因素、脱水工艺发展以及该技术存在的问题等方面进行了综述,并对该技术的发展做了展望。With the development of China’s economy,a large number of activated sludge need to be dewatered every year.However,the traditional sludge dewatering treatment is difficult to meet the requirements of relevant standards for sludge disposal in China.Therefore,it is urgent to explore a new process of deep sludge dewatering to meet the requirements of China’s economic development In this paper,the principle of dehydration,influencing factors of dehydration,the development of dehydration technology and the existing problems of this technology are reviewed,and the development of this technology is prospected.
