摘　　要：探索了硫酸铝(Al2(SO4)3)和聚丙烯酰胺(PAM)加入顺序、用量、水力条件、pH等对两者协同除浊效应的影响,确定了两者结合使用时的最佳工艺条件。并将分别用处理前后的河水及自来水所抄的手抄片进行了比较。结果表明:当Al2(SO4)3用量为35mg/L时,处理水浊度由150NTU降低到1.5NTU。处理后水抄得的手抄片与处理前相比,白度提高了67.05%,与用自来水所抄的手抄片白度相当。The influences of adding sequence and dosage of aluminum sulfate （ A12 （ SO4 ） 3 ） and polyacrylamide （PAM）, hydrodynamic conditions and pH on their synergistic turbidity removing effect were explored, and the optimal conditions were also determined. At the same time, handsheets from water before and after treatment, and tap water were compared. The results show that when A12 （ SO4 ） 3is used at the dosage of 350 mg/L, the turbidity decreases from 150 NTU to 1.5 NTU. Compared with handsheets from water before treatment, the brightness of handsheets from water after treatment is increased by 67.05%, which approximates the brightness of handsheets from tap water.
