Title: Application of anionic polyacrylamide to sludge dewatering of papermaking wastewater
Abstract: The possibility that anionic polyacrylamide takes the place of cationic polyacrylamide has been studied.The paper discusses the effect of the quantity of anionic polyacrylamide,etherificatin,buffering time and pH on the efficiency of sludge dewatering.The results show that the effect of anionic polyacrylamide can be nearly as good as that of cationic polyacrylamide,which can reduce cost.Taking economic factor and effect of sludge dewatering into account,this experiment proves the best quantity of anionic polyacrylamide,the proportion of anionic polyacrylamide to etherification,the best time of buffering,the best pH and so on.
