摘要
采用硅酸钠碱化聚合方法制备聚铝铁硅絮凝剂,研究它们的pH弛豫规律及其稳定性,并通过流动电流测定了其电动特性。最后进行了混凝除浊(富里酸)效果对比研究,初步得到了稳定性及絮凝效果均较好的聚合铝铁硅絮凝剂的工艺合成方法。
A synthetic method of polyaluminum-ferric-silicate flocculant was studied by the netralizing and polymerzing with silicate. The pH relaxation and stability of the flocculant were investigated. Its electrokinetics and flocculation effect were studied by the streaming current and jar test. A synthetic method of the polyaluminum ferric silicate flocculant with chemical staility and good flocculation effect were obtained.
