【摘要】 评述了絮凝机理的两种观点。聚合铝广泛应用于水处理中。为提高聚铝絮凝性能,已报道了大量文献,开发出了多种新型絮凝剂,如聚合硫酸氯化铝、聚合磷酸氯化铝、聚合铁铝、聚合硅酸铝等。并就无机—有机高分子絮凝剂联用作了阐述,提出了聚合铝絮凝剂在今后水处理方面的发展趋势。更多还原

【Abstract】 Polyaluminium has been widely used in water treatment. Two views of flocculent mechanism are stated in this paper. To improve its flocculation properties, a lot of work has been done. Several new flocculating agents have been developed, such as polyaluminium chloride sulphate, polyblend of phosphate and aluminium, polyblend of iron and aluminium, polyblend of silica and aluminium etc. The combining use of polyaluminium and organic polymeric flocculant has been discussed in this paper. The developmental trend of polyaluminium in water treatment is discussed.更多还原
