| Abstract: | 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. |
