摘要:目前,饮用水处理中的絮凝阶段主要依赖铁(Fe)盐和铝(Al)盐,聚合氯化铝铁(PAFC)是一种新型,高效无机阳离子复合絮凝剂,PAFC既具有铝盐絮凝剂矾花大、水处理面宽、除浊效果好、对设备管路腐蚀性小等优点;还具有铁盐絮凝剂絮题沉降快、易于分离、低温水处理性能好、水处理PH值范围大等特点.但是聚合铝盐类絮凝剂及其水解产物存在着沉降速度(略)量大、除色效果差、残余铝具有毒性等缺点,而聚合氧氯化锆的絮凝性能主要体现在,它能提供大量的络合离子,且能够强烈吸附胶体微粒,通过吸附、桥架、交联作用,从而使胶体凝聚,同时还发生物理化学变化,中和胶体微粒及悬浮物表面的电荷,降低了δ电位,使胶体微粒由原来的相斥变为相吸,破坏了胶团稳定性,使胶体微粒相互碰撞,从而形成絮状混凝沉淀,沉淀的表面积可达(200~1000)m2/g,极具吸附能力.研究聚合氧氯化锆絮凝性能对更好地开发氧氯化锆资源,为国家各项事业服务,满足社会各方面的需求.

Abstract: at present, the flocculation in water treatment stage mainly depends on the iron (Fe) and aluminum (Al) salt, salt polyaluminium chloride (PAFC) is a new type of iron, high efficient inorganic cation compound flocculant, PAFC has both aluminum salt flocculants alum flowers large, wide, in addition to the turbidity water treatment effect is good, and the advantages of small pipe corrosion to equipment; Flocculant with ferric salt flocculants are problem settling fast, easy separation, low temperature performance is good water treatment, water treatment, wide PH range, etc. But polymerization aluminum salt flocculants and their hydrolysis products there is a large amount of subsidence velocity (slightly) and residual aluminum in addition to the color effect is poor, has the shortcomings such as toxicity, and oxygen zirconium chloride polymer flocculation performance is mainly embodied in that it can provide a large number of complex ions, and can strong adsorption of colloid particles, by adsorption, bridge, crosslinking effect, so that the colloid agglomerated, and physical and chemical changes, and the charge on the surface of the colloidal particles and suspended solids, reduces the delta potential, the colloidal particles repel has attraction, destroyed the micelle stability, the colloidal particles collide with each other, thus forming a flocculent coagulation precipitation, precipitation of the surface area of m2 / g (200 ~ 1000), adsorption capacity. Study of aggregation of oxygen zirconium chloride flocculation performance to better develop the oxygen zirconium chloride resources, for the country's career services, meet the needs of the social various aspects.
