Abstract
PURPOSE: To contrive to miniaturize an installation by a method wherein an activated sludge exhausted from a water treating apparatus is concentrated forcedly by a mechanical method and, thereafter, subjected to anaerobic treatment.
CONSTITUTION: An activated sludge subjected to floatation separating treatment in a water treating apparatus 1 and exhausted therefrom is supplied to a forced concentration apparatus 2 such as a centrifugal dehydrator or the like and subjected to forced concentration treatment mechanically. Thereafter, the concentrated sludge is supplied to a self-digestion tank 3 to be allowed to stand for a predetermined time and subjected to self-digestion under a hermetically sealed anaerobic atmosphere to reduce a sludge amount. Thereafter, said digested sludge is separated into a solid component such as a sludge cake and water and the solid component is subjected to incinerating treatment and, on the other hand, the water is subjected to post treatment after sterilization, thereafter taken out as a fresh water.
