Abstract :
By comparing with freezing-thawing conditioning and other chemical conditioning method, the leading role of PAM is played in waterworks sludge conditioning. The result shows that the quantity ratio of PAM shall be about 10/00, the concentration shall be about 2% and the optimum stirring intensity shall be 230 r/min. After adding PAM, there exist apparent boundary lines in the sludge. The lower floes are compact and big, which is helpful for later concentration and dehydration.
