Abstract

The treating processes of papermaking waste water by PDA prepared by our laboratory and some kinds of cationic poly acry lamide in the market are reported.The performances of inorganic coagulant(PAC), organic flocculant(cationic polyacrylamide)and the composite of inorganic and organic flocculants in treating papermaking waste water have been compared.The results show that the performance of the composite of inorganic andorganic flocculants is excellent.COD elimination efficiency of the treated water can reach75% or more, and the transmit tancy can reach 92%-99%
