摘要: The rheological characteristics of the wastewater sludge were investigated by using a Haake Rheostress RS 75 rheometer. stress-sweep experiments and small-amplitude-oscillatory-shearing (SAOS) tests conducted. measurements demonstrate that addition polymer coagulants to samples could significantly influence corresponding complex shear modulus G*. Furthermore, SAOS indicate treated with will form more rigid structures. original mostly show typical viscoelastic liquid-like behavior. However, solid-like behaviors always observed in polymers.
