| 摘 要： | 制备了高分子复合絮凝剂聚硅酸硫酸铁（PFSS）-助凝剂壳聚糖（CTS），探讨了其组成、投加量、水样pH值、沉降时间对黄河水絮凝效果的影响，得出最佳的应用条件：m（PFSS）：m（CTS）=5：1，投加量（15＋3）mg／L，水样pH值5～10，沉降时间10min。在上述条件下采用PFsS—cTS处理黄河水后其浊度、色度、磷含量、COD去除率分别达到96．86％，92．45％，95．01％，90．15％。

| Abstract: | Compound flocculant comprising PFSS - CTS was synthesized. The effects of some factors such as composition, amount of flocculant added, pH value, setting time on the flocculation of water in the Yellow River were examined. The optimum conditions for application of PFSS - CTS in treatment of water were obtained as follows ： m （PFSS） ： m （CTS） = 5 ： 1, dosage of PFSS - CTS （ 15 ＋ 3 ） mg/L, pH of water 5 - 10, setting time 10 minutes. The removal rates of turbidity, chromaticity, phosphorous and COD were up to 96.86% ,92.45 %, 95.01 ,and 90.15 respectively. |
