Mechanism Study of Excess Sludge Disintegration by Stirred Ball Mill

Abstract:

Stirred ball mill(SBM) method is one of the usually method which applied in large scale application cases of sludge disintegration. This study focuses on investigation the mechanism of sludge disintegration by SBM method. Besides analysis general indicators of SCOD, TN, TP and calculated the disintegration rate of COD (DDCOD). The result indicated the SCOD and DDCOD increased with the disintegration time. As DDCOD increased to the highest of 18.6% at the treated time of 60min, it shown that SBM was not more efficient in disintegration of biomass into so smaller particle that easily dissolved in water.
