Research on the rheological property of low-rank bitumite coking wastewater slurry
Coking wastewaters components are complex, leading to treatment difficulties.Preparing the wastewater to slurries with low-rank bitumite can not only transform the high pollution components to simple and easy-treated inorganic molecules, but also utilize the heat it creates, and at the meanwhile expand the low-rank bitumites application scope.Three coking wastewater samples of different treating depth, from a coking plant in Tangshan, were prepared slurries with a low-rank bitumite from a mine in Shanxi, and the slurries theological and temperature-depended properties were also tested.The results indicated that: preparing slurries with the feed of clean-room can optimize the flow-ability of which is with clean water; the viscosities reduce when heating the slurries, until the temperature increase over a unique value; the change pattern of the viscosity is depended on the properties of the interstitial water, water film and dispersant molecules by heating the slurries.
