| 摘 要： | 介绍了絮凝剂选择与配置的方法,阐述了絮凝剂性能试验方法的原理.通过对絮凝剂自由沉降速度测定试验,分析出单独使用絮凝剂能取得较好的沉降效果;通过絮凝剂初始沉降速度测定试验,分析出絮凝剂用量达到一定程度时,处于饱和状态,沉降速度不再增加,反而会降低.根据易泥化煤种煤泥水沉降试验,分子量为1000万的阴离子型聚丙烯酰胺的沉降效果较好.

| Abstract: | The paper introduced flocculation medicament choice and collocation way,and described the flocculation experiment method and principle.By the measurement experiment of the flocculation freedom settlement rate,the better settlement effects under single flocculation was analyzed.By flocculation begin settlement rate measurement experiment,the important conclusion was obtained that: when flocculation dosage attained to a certainty degree(saturation condition),coal slurry settlement rate can be saturated not in... |
