Parameter optimization of coagulation and sedimentation for fine suspended solids removal from mine water

  • 摘要: 针对宝日希勒露天煤矿矿井水中悬浮颗粒物粒径小、难去除的问题,采用单因素与正交实验方法确定了混凝沉淀工艺的最佳参数,分析了矿井水中细颗粒物的混凝机理。结果表明,混凝沉淀的最佳工艺参数为聚合氯化铝(PAC)投加量50 mg/L,非离子型聚丙烯酰胺(NPAM)投加量5.0 mg/L,快速搅拌(300 r/min)时间1 min,慢速搅拌(50 r/min)时间8 min,静置时间5 min;在最佳工艺条件下,悬浮物(SS)质量浓度为5.0 mg/L,去除率为99.1 %,相比单独投加PAC时,10 μm以下的细颗粒物去除率提高了25.9 %,矿井水的ζ电位由-40.9 mV降低至-16.3 mV,说明细颗粒物的混凝机理主要为PAC吸附电中和作用和聚丙烯酰胺(PAM)吸附架桥作用。
