Research on flocculation effect of fly ash composite on high turbidity and high salinity mine water

  • 摘要: 煤矿分布式地下水库在神东地区应用取得显著成果,宁东地区已开始论证其可行性,但宁东地区矿井水多为高浊度高矿化度矿井水,需要对水库入水进行预处理。本文采用以粉煤灰为原料,通过与聚丙烯酰胺(PAM)、聚合氯化铝(PAC)、壳聚糖混合得到处理高浊度高矿化度矿井水的絮凝剂,试验对比了粉煤灰基复合絮凝剂和未加粉煤灰絮凝剂的絮凝效果,并探究了粉煤灰基絮凝剂的影响因素,确定了最佳投加量和试验条件。实验结果表明:① 5个处理组中对矿井水的处理效果依次是:PAM+PAC+壳聚糖+粉煤灰>PAM+PAC+壳聚糖>PAM+PAC>PAM>PAC;② 粉煤灰基复合絮凝剂的最佳絮凝条件为温度25℃、pH值7、搅拌强度220 r/min、搅拌时间20 min;③ 在最佳条件下,复合絮凝剂对矿化度、悬浮物、钙离子、总硬度和硫酸根的去除率分别为1216%、9804%、8057%、7786%和9544%;④ 粉煤灰基复合絮凝剂作为地下水库处理高浊度高矿化度矿井水预处理絮凝剂是可行的。本研究为地下水库进水的絮凝等预处理提供理论依据和技术支撑。
