Abstract Municipal sludge is a sedimentation waste produced during the wastewater process in sewage treatment plants.
Among recent studies, pilot and field tests showed that chemical conditioning combined with vacuum preloading
can effectively treat municipal sludge. To further understand the drainage and consolidation characteristics of the
conditioning sludge during vacuum preloading, a large deformation nonlinear numerical simulation model based
on the equal strain condition was developed to simulate and analyze the pilot and field tests, whereas the simulation results were not satisfactory. The results of the numerical analysis of the pilot test showed that the predicted
consolidation degree was greater than… More >
