Abstract
PURPOSE: To pulverize sludge with high efficincy while suppressing an energy consumption, by mixing a relarively laege amount of quick lime with waste sludge, adding a fixed amount of Mohr's salt to the mixture, and heating and agitating the mixture.
CONSTITUTION: Waste sludge generated in the treatment of waste water from a sewer system is mixed with 10% by weight or more of calcium oxide. Thereafter 5% by weight or more of ammonium ferrous sulfate (so-called Mohr's salt) is added to the mixture. The mixture is then heated and agitated. According to this treatment, the sludge can be pulverized with high efficiency while saving an energy consumption.
