Studies On The Carbonization Mud Using As Liming In The Sulphitation

Mixed juice separation and purification is the highest cost and more difficult process in cane sugar mill, it is vital for sugar manufacture and mostly decides the quality of sugar products . In sugar technics, calcium carbonate is a sort of sorbent. It is a good sorbent.It can remove colloid, coloring matter and non-sugar by adsorption. Furthermore , it is also good for filtration, and is helpful for sedimentation of non-sugar. Carbonatation sludge are activated with milk of lime and then recycled to liming. The use of regenerated CaC03 crystals from first carbonatation mud raised the purification efficiency and facilitated sludge separation and reduce comsumption of lime.The follow was the main contents in this research paper.1.Effect of calcium carbonate on adsorption feature and adsorption mechanism after surface modification by surfactant.2.The research on regenerated carbonatat ion mud used insulphitation process. Disposing the mixed juice by using regenerated carbonatation mud by orthogonal experiments, measured the decolorization effect, settling velocity, purity difference as well as filtration velocity, then found out the best technological conditions requirements by range analysis and the marked factors of decolorization effect , settling velocity and purity difference as well as filtration velocity by variance analysis .3. The decolourization of ampholytic polyelectrolyte . Based on Ultraviolet spectrum of predisposing and disposed cane ju i ce , stud i ed the variation of the coloring matters,including phenolic matters, organic matter and reducing sugar decompounds .
