Study on influencing factors and function mechanism of CPAM for regulation of concentrated sludge
CPAM调质浓缩污泥脱水的影响因素及其机理研究

The treatment of excess sludge is a focus at present. With concentrated sludge as research subject, the flocculating effect of cationic polyacrylamide (CPAM) amount, sludge pH, environment temperature and stirring way were investigated. At the same time, dewatering mechanism was also studied elementarily. The results of the experimental showed that under the optimum dosage of CPAM, sludge pH valve range from 5.0 to 7.5 and low speed of stirring, CPAM had better dewatering effects. And environment temperature also influenced the dewatering effect, the effects of regulating in the summer were better than in winter.
