无机高分子聚合铁盐类混凝剂制备方法评述(英文)

Progress on Manufacturing Method of Inorganic Polymer Coagulant Polyferric Salt Category

综述了无机高分子聚合铁盐类混凝剂的几种生产制备方法.对用硫酸亚铁经催化氧化法和直接氧化法制备聚合硫酸铁,用各种含铁工业废渣制备复合聚铁,以及采用生物和电化学方法制备聚铁类混凝剂等方法的优缺点等作了较全面评述.还对固体聚合铁的生产及液体聚合铁混凝剂的稳定性进行了讨论,对目前聚合铁生产中存在的问题及发展方向提出了建议.

This paper gives a review of the manufacturing method of inorganic high polymer coagulant polymerized ferric sulfate(PFS). The present situation of the studies and the production of PFS is discussed. It points out the merit and the shortcoming of the manufacturing methods of PFS with ferrous sulfate, pyrite cinder and other slags containing iron. Some suggestions about present problems and development direction in the production of PFS have been put forward.
