摘　　要：用流动电流技术研究了聚合氯化铝（PAC）分别与不同类型有机高分子制备复合絮凝剂（PACP）的电荷特性，并利用透射电镜技术探讨了PACP的结构形貌。同时利用自制的复合絮凝剂对造纸综合废水的浊度、色度和COD的脱除效果进行了研究。结果表明：与PAC相比，PACP的脱除效果有明显地提高；PAC-阳离子型有机高分子复合絮凝剂的效果又优于PAC-阴离子型有机高分子复合絮凝的效果。The electrical charge features of polyaluminum-organic polymer composite（PACP） flocculants were studied by streaming current （SC） detecting technology， and the morphologies of PACP were investigated by transmission electron microscope（TEM）． The removal efficiency of turbidity， chromaticity and COD of effluent of paper mill by using PAC and PACP were also compared． The results show that the removal efficiency of PACP is better than that of PAC，andremoval efficiency of PAC─cationic organic polymer composite（PACPc） is better than that of PAC─anionic organic polymer composite（PACPa）．
