Progress of coal-water slurry technology with waste disposal synergy
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.
