The effects of ball mill pretreatment and Mn catalytic ozonation on the reduction of sewage sludge were investigated. The ball mill pretreatment increased ΔSCOD from 2,000mg/L to 9,000 mg/L, as Total Solids (TS) increased from 1% to 4% at a specific energy of 75.8 KJ/g-TSS. The increase in disintegration ratio (DR), which is an index of the solubilization …
