采用碱化法,在引入PO_4~(3-)制备聚合磷硫酸铁的过程中加入改性凹凸棒,制备出新型复合无机高分子絮凝剂聚合磷硫酸铁-凹凸棒(APPFS),并运用傅立叶红外光谱仪和扫描电镜等仪器对APPFS进行表征,同时通过处理黄河水来考察其絮凝性能.结果表明:当APPFS的盐基度为0.3、P/Fe为0.05、投加量为4 mg/L、原水pH值为8左右时,APPFS的絮凝性能最佳,除浊率达到98.93%,且其絮凝效果明显优于传统絮凝剂PAC的.

A novel inorganic macromolecule flocculant, polyphosphate ferric sulfate-attapulgite ' (APPFS) was synthesized by introducing phosphate ion into polyphosphate ferric sulfate and adding mod-ified attapulgite.The prepared APPFS was characterized by FT-IR and SEM, and the flocculation per-formance of APPFS in treatment of Yellow River water was investigated.The results show that when the basicity is 0.3, P/Fe molar ratio is 0.05, APPFS dosage is 4 mg/L, and pH value of raw water is 8, the optimal flocculation performance is achieved, and the removal rate of turbidity is 98.93%.Also, the flocculation efficiency of APPFS is better than that of PAC.
