The t reating processes of cationic flocculant PDA on papermaking w astew ater are reported in this paper.The flocculating behaviors of ino rganic polymer coagulant (PFS or PAC), PDA and the composites of PFS or PAC and PDA are studied respectively.The results shows that the composite of PAC and PDA in the treatment of papermaking wastewater is more ef fective.Compared w ith the sample of higher cation, the sample of higher molecular weight in the treatment is mo re important.Af ter treatment, COD of w astew ater can be reduced by 74 %～ 77 % and the transmit tancy can reach 92 %～ 99 %.The formed floc.is solid and can easily be dewatered.
