【摘要】 将聚合硫酸铁 (PFS)与聚合硫酸铝 (PAS)按一定比例混合 ,即可制得一类具有不同铝铁含量的新型净水剂——聚合硫酸铁铝 (PFAS)混合液 ,分析、检测了几种 PFAS的性质及其净水性能。结果表明 ,PFAS的综合性能优于 PFS和PAS,更能适应原水水质的变化 ,其中尤以铝铁分子摩尔比为 0 .64的 PFAS性能最优。更多还原

【Abstract】 Mixed polymerized ferric sulfate(PFS) with polymerized aluminum sulfate(PAS) according to definite proportions,a new kind of water clarifying agents polymerized ferric-aluminum sulfates(PFAS s) with different molecular ratio of aluminum to ferric have been synthesized in our laboratory.The proporties and water-clarifying performance of PFAS s have been measured and discussed in details.The experimental results show that PFAS s that better comprehensive properties in the suitability to varying water quality than PFS and PAS,and the best is that with 0.64 molecular ratio of aluminum to rerric.更多还原
