摘　　要：以硫酸铝、硫酸铁、水玻璃为主要原料制备了聚合硅酸铝铁(PSAF)絮凝剂.研究了用PSAF处理板桥水库、练江河和驻马店某造纸厂废水的絮凝性能,并与用PAC的处理效果进行了比较.考察了不同絮凝剂对水样的去浊率、COD去除率和色度去除率的差异.结果表明:在相同的有效浓度下,聚合硅酸铝铁处理水的性能明显优于PAC.The PSAF floccule is produced with sulfate aluminum, sulfate iron and water glass as the main material. Researching the capability of flocculation on disposal of the waste water of Banqiao Reservoir, Lianjianhe River, and the papermill in Zhumadian, the capability of the PSAF is compared with that of the PAC. Inspecting the difference in the disposalrate on trial degree COD and colour degree of the water sample. It shows that the capability of the PSAF is superior to that of the PAC in the same effective concentration.
