废弃物处置协同制备水煤浆技术研究进展

Progress of coal-water slurry technology with waste disposal synergy

阐述了近年来人们掺配不同废液与废固所制水煤浆的浆体性质,其中包括焦化废水、含油废水、印染废水、造纸黑液等废液所制水煤浆以及采用化工污泥、含油污泥、煤气化细渣、煤泥等固废所制水煤浆,分析了不同预处理与改性方式对浆体性能的影响,并对掺配废弃物制浆的技术瓶颈与未来发展趋势进行了展望。

The properties of CWS made by mixing different waste liquid and solid in recent years,including the CWS made from coking wastewater,oily wastewater,printing and dyeing wastewater,papermaking black liquor,and solid wastes such as chemical sludge,oily sludge,coal gasification fine slag,and coal slime,were described.The effects of different pretreatment and modification methods on the properties of the slurry were analyzed.The technical bottleneck and future development trend of blended waste pulping were also prospected.
