英文摘要: This study investigated the effects of chemical conditioning with amphoteric terpolymer poly (acrylamide-’acryloyloxyethyl trimethyl ammonium chloride -2-acrylamido-2-methyl-propane sulfonate) (PADA) on sludge dewaterability. Particle size, fractal dimension, surface charge, extracellular polymeric substances (EPS) and trivalent metal ions (Al3+ and Fe3+) of sludge were monitored and Pearson statistical analysis was used to understand the correlation of dewaterability and physicochemical properties of sludge. The results revealed that: (1) Sludge dewaterability was significantly enhanced by amphoteric polymer PADA. (2) Particle, fractal dimension and surface charge of sludge were associated with anionic degrees and molecular weights of polymer. (3) PADA had apparent...
