Mechanism Investigation of Excess Sludge Disintegration

2021-6-3  Abstract The stirred ball mill (SBM) method is a common method applied in large-scale sludge disintegration. Many reports focus on the disintegration results of sludge or the influence of parameters on the anaerobic process of treated sludge, but there have been few studies on the mechanism of sludge disintegration by SBM. This study focused on the mechanism of sludge disintegration by the SBM ...
