Method for disintegrating sewage sludge

Abstract

There is a method for the mechanical disintegration of biogenic sewage sludge, for which the sewage sludge, in an initial state, has microorganisms in the form of cells and a solid, which is formed essentially from aggregates of cells and suspended materials, and for which a disintegration process (3, 4) causes a destruction of aggregates and a destruction of cells. It is desirable to improve the disintegration. This is achieved in that, in a first disintegration step 3, primary destruction of aggregates and, in a subsequent, separate second disintegration step 4, primary destruction of cells is caused. Due to the use of two separate disintegration processes, an appreciable improvement in the disintegration is achieved, since fewer aggregates and more cells are supplied to the second disintegration process. The increased destruction of cells brings about the improvement in the disintegration.
