Abstract

Procedure for composting clarification sludge by means of a decomposition process governable through the air supply, characterized in that the clarification sludge is intermixed with an organic carbon carrier and introduced into an aeration reactor; because the oxygen from the air required for the decomposition process, and to which pure oxygen has been dosed, is introduced into the aeration reactor at the bottom thereof, also continuously and by the counter-current procedure, in such a way Thus, different temperature and O2 zones are formed in the aeration reactor, with the zone with the highest temperature in the upper third, and the zone with the lowest temperature at the outlet, while the zone with the highest content of Oxygen is at the bottom, and the lowest oxygen content zone, in the upper end layer of the aeration reactor.
