摘要
污泥脱水是实现污泥减量化的重要技术之一,提高脱水效率不仅能有效减少污泥体积,而且能满足后续污泥处理处置对含水率的要求。基于预处理的强化污泥脱水技术研发已成为当前污泥脱水的一个热点领域,其中预处理包括化学、物理和组合技术。通过文献调研,总结分析了现有污泥脱水技术的应用现状及其难点,并对基于预处理的强化污泥脱水研究及其应用情况进行了系统分析,以期为我国今后污泥脱水研究与应用提供参考。
Sludge dewatering is one of the important technologies for sludge reduction,and improving sludge dewatering efficiency can effectively reduce sludge volume and meet the requirements for moisture content of sludge in further sludge treatment and disposal. Therefore,enhancement of sludge dewatering by pretreatment is becoming one of great concerns,including chemical,physical and combined sludge pretreatment technologies. The current applications and difficulties of existing sludge dewatering technologies were summarized and analyzed by literature research,and research and application of sludge dewatering enhanced by pretreatment were reviewed in order to provide reference for sludge dewatering in China.
