快速絮凝剂及其制备方法
摘要：
本发明公开了一种快速絮凝剂及其制备方法，所述絮凝剂的化学成分按重量百分数比计由：混沉池污泥75~85%、高炉渣粉5~15%、硫酸铝氨2~10%、聚合硫酸铁2~10%和1~2%添加剂组合而成。该制备方法先后按比例将硫酸铝氨、聚合硫酸铁、混沉池污泥、高炉渣粉在80~200r/min条件下搅拌；得到快速絮凝剂。本发明的絮凝剂由混沉池污泥及高炉渣粉组成，高炉渣粉表面具有较大的活性，可使絮凝加快，从而达到快速絮凝的目的，实现固体废弃物的资源化利用和高附加值利用。
摘要（英）：

The invention discloses a fast flocculating agent and its preparation method. The flocculating agent comprises the following chemical components by weight: 75-85% of mixed sedimentation tank sludge, 5-15% of blast furnace slag powder, 2-10% of aluminium ammonium sulfate, 2-10% of polymeric ferric sulfate and 1-2% of an additive. According to the preparation method of the invention, the aluminium ammonium sulfate, the polymeric ferric sulfate, the mixed sedimentation tank sludge, and the blast furnace slag powder are successively stirred in proportion under the condition of 80-200r/min so as to obtain the fast flocculating agent. The flocculating agent of the invention is composed of the mixed sedimentation tank sludge and the blast furnace slag powder, the surface of which has great activity and can speed up flocculation, thus reaching the purpose of fast flocculation and realizing resource utilization and high value-added utilization of solid waste.
