复合聚氯化、硫酸铝铁的研制

Preparation of Complex Polyaluminium Iorn Chloride and Sulphate

利用当地的废料制备出会有Fe3+、Al3+二种金属离子的复合聚氯化、硫酸盐脱色絮凝剂。它是一种新型的产品，具有聚氯化铝的特点，又具有聚硫酸铁的特点。介绍了产品的制备、测试方法及质量。最后对絮凝机理及结构进行了讨论。试验表明它是一种高效的新型净水剂，具有广阔的开发前景。

The complex poyaluminium Iron chloride and sulphate, decolourant and flocculant, condristwo kinds of metal ions Fe3+ and Al3+, which is prepored by the local waste matertals.It's a new type of produclion which has the characteristics of polyaluminium chlorthe and poly-iron sulphate. This paper introduces the preparation. the determined methods and quality of this production, discusses the structure and the floccular mechanism at lan. It's proved by the experiments thatit's a new type of chanaing water agent with hgh efficency, which has wide developing foregtound.
