摘　　要：本文分析了市政污泥的物性特征,探讨了污泥制备浆体燃料的研究现状及其优势所在,剖析了污泥制浆技术的未来发展方向,并提出了利用发酵机制破解污泥絮体结构的新方案。利用发酵机制破解污泥絮体结构,絮体的内部空间得以充分打开,大量束缚水得以释放,有助于从根源上解决由污泥高水分带来的应用问题。利用发酵污泥制备浆体燃料,可大幅提高污泥掺混比,为市政污泥的大规模能源化利用开辟了新思路。This paper analyzed the physical characteristics of municipal sludge,and discussed the research status and advantages of preparing slurry fuel from sludge,and predicted the future development direction of sludge pulping technology.The authors also put forward a new scheme of cracking sludge floc structure by using fermentation mechanism.Using fermentation mechanism to break the structure of sludge floc,the internal space of the floc can be fully opened and a large amount of bound water can be released,which is helpful to thoroughly solve the application problems caused by the high moisture of sludge.Using fermented sludge to prepare slurry fuel can greatly improve the sludge mixing ratio,which opens up a new idea for large-scale energy utilization of municipal sludge.municipal sludge;slurry fuel;floc structure;fermentation mechanism;energy utilization。
