- W4382519306 abstract "When using cationic polyacrylamide (CPAM) to flocculate dredged sludge with extremely high water content, the pore structure change mechanism of the flocculated slurry cannot be accurately judged only by the amount of supernatant liquid in the particle gradation test and flocculation test. Therefore, this article first carried out 6 groups of cationic polyacrylamide (CPAM) flocculation experiments with different dosages, and obtained the fastest flocculation speed when the dosage was 0.4‰ and the amount of clear liquid precipitated was relatively large. The main parameters of the dredged mud before and after flocculation were analyzed by adding mercury intrusion test to the sediment of CPAM-0.4 group, in order to clarify the change mechanism of the pore structure of the mud in the flocculation test. The results show that the volume of pores with a pore diameter in the range of 0.1–10 μm increases, while the volume of pores with pore diameters in other ranges decreases; the skeleton structure inside the soil particles is more simplified, while the pore structure is more complex and irregular." @default.
