Abstract

Method and plant for the continuous treatment of biological sludge for the recycling thereof for agricultural purposes, comprising the steps of a) conveying a densified product from a biological water treatment plant; b) thickening the densified product until a sludge with a predetermined percentage of dry matter is obtained; c) mixing the sludge with a hygienizing treatment product in controlled chemico-physical conditions in order to promote hygienizing treatment thereof; d) maturing the sludge for a predetermined period of time in order to complete hygiening treatment; e) storing the hygienized sludge until it is extracted for use; f) distributing the hygienized end products; characterized in that all said steps are performed in continuous flow conditions and in substantially steady state chemico-physical conditions.
