Abstract
Aiming at the problems of strong viscosity and low transportation efficiency of temporary stored sludge in Laogang Shanghai, an experimental study on sludge thixotropy was carried out to study the changes of sludge viscosity with shear rate and standing time, the changes of shear stress with shear rate at different solid content, and the changes of sludge shear stress with time at constant shear rate at different solid content. On this basis, dynamic equilibrium rheological curves for different solid content were established, and numerical simulation techniques were used to form a mathematical expression of the dynamic equilibrium rheological curve for temporary storage sludge. The thixotropic index for different solid content was obtained, providing theoretical support for efficient transportation of temporary storage sludge.
