Polyaluminium chloride as a kind of high efficient coagulant has been widely used at home and abroad. It has advantages such as less consumption, less sludge, high turbidity, small effects on water pH and so on. We reviewed the research progress of polyaluminium chloride preparation technology. Aiming at the pollution problem caused by acid-leach residue’s froming during the production, we use acid dip slag, aggregate chloride aluminum and the cationic polymer, with proper technology, to make an efficient composite polymer flocculation which has unique structures of a central metal ion and mineral crystal nuclear. Finally, we determined the optimum flocculation formula by flocculation coagulation experiments and the cost comparison. This formula can not only transform the pollution acid-leach residue into valuable production resource , but also reduce the flocculation production cost and increase enterprises' economic benefit.
kywords: production cost, Polyaluminium chloride, economic benefit, flocculation
