NIE Li-jun~1,LI Lin~2,LI Hong-mei~3,LI Chun-hui~1,LIU Yan-wen~1,YANG Jian-she~1(1.Maoming College, Maoming, 525000, China;2. Lliaoyuan EP bureau of Jilin province , . Lliaoyuan 136200,China;3.School of Chemical and Environmental Engineering ,CUMT, Beijing, 100083,China)  
By studying compound process of PFS, a set of techniques of compounding solid PSAFS is devised in the paper, called one-step preparation of solid PSAFS. Through the coagulating test to treat simulating turbid water, the best parameters have been obtained by applying orthogonal design: Fe/Si molar ratio , Na_2SiO_39H_2O solution polymerizing time, reacting time, reacting temperature and Al/Si molar ratio.
