摘　　要：In this paper, the application of modified polyacylamide is discussed and the complex systems of PAC/modified PAM are used to treat the papermaking wastewater. The results showed that when cationic polyacylamide (CPAM) and amphoteric polyacylamide (AmPAM) were used at the dosage of 0.75ppm with PAC, of which the optimum dosage was 100ppm, the removed rate of CODcr was above 80% .In this paper, the application of modified polyacylamide is discussed and the complex systems of PAC/modified PAM are used to treat the papermaking wastewater.
