摘　　要：为进一步提升选煤厂煤泥水的处理效果,解决煤泥水处理不当对环境造成污染和资源浪费的问题,在对煤泥水质特性检测的基础上,结合理论研究提出适用的最佳混凝剂,并对不同混凝剂添加量对不同浓度煤泥水出水浊度的影响,对不同GT值对不同浓度煤泥水出水浊度的影响,最终得出适用于本煤泥水的最佳工艺参数。In order to further improve the treatment effect of slime water in the coal preparation plant,and solve the problems of environmental pollution and resource waste caused by improper treatment of slime water,based on the detection of the water quality characteristics of slime,combined with theoretical research,the optimal coagulant is proposed,and the effect of different coagulant additions on the turbidity of slime water of different concentrations,and the effect of different GT values on the turbidity of slime water of different concentrations,Finally,the best process parameters applicable to the coal slurry are obtained.
