Study on flocculation settlement of high slime water in Xieqiao Coal Preparation Plant
The treatment of high slime water has always been the difficulty and key point of coal preparation plants,and its treatment efficiency has seriously affected the normal production of coal preparation plants.This study examines the degree of slime in raw coal washed at Xieqiao coal preparation plant and its impact on the coal slime water treatment system through experimentation.The results indicate that the range analysis showed that the turbidity and sedimentation rate of the clarified layer were taken as the investigation indexes,and the primary and secondary factors were A(flocculant)＞B(coagulant)＞C(slime water concentration),and the optimal settlement conditions were A3B3C1.Analysis of variance showed that the concentration of flocculant had a significant effect on the turbidity and sedimentation rate of the clarified layer after the settling of the slime.
