摘　　要：伴随着国家对污泥处置及资源化管理要求提高,如何降低污泥含水率、减少污泥体积成为重点问题,实现污泥深度脱水是有效解决此问题的途径之一。传统的污泥处理技术存在脱水极限,对干燥设备的性能要求也随着含水率降低而提高,找到一种低能耗、高效率的深度脱水方法成为当下急需解决的问题。借鉴国外在物料深度脱水的理论与应用,在我国现阶段高压板框深度脱水技术与热压干化技术的基础上,提出污泥真空压滤联合过热蒸汽高效脱水技术。该技术能在同一设备上完成机械压力过滤与热力干燥脱水,更加节能、高效、环保。With the improvement of the national requirements for sludge disposal and resource management,how to reduce the water content and volume of sludge has become a key problem,and realizing the deep dewatering of sludge is one of the effective ways to solve this problem.The traditional sludge treatment technology has dehydration limit,and the performance requirements of drying equipment are improved with the reduction of water content.Finding a low energy consumption and high efficiency deep dehydration method has become an urgent problem to be solved.Based on the theory and application of advanced material dewatering abroad and the advanced dewatering technology of high pressure plate and frame and hot pressing drying technology in China,the efficient dewatering technology of sludge combined with vacuum pressure filtration and superheated steam is proposed.This technology can complete mechanical pressure filtration and thermal drying dehydration on the same equipment,which is more energy saving,efficient and environmental protection.
