ABSTRACT:
A sewage sludge-irradiation device for irradiating sewage sludge with radiation having a sterilizing effect. A conveyor system embodies at least two conveyor devices, at least one of which conveyor device is supplied with a layer of sewage sludge. The conveyor devices are arranged in a manner to form therebetween a passageway defining a mixing gap for the through-passing sewage sludge. A relative movement exists between the two conveyor devices, and radiation means cooperates with the conveyor system for irradiating the sewage sludge at a location prior to intermixing thereof in the mixing gap. The conveyor devices can be driven to possess respectively different speeds of movement, and it is also possible for one of the conveyor devices to be driven and the other to be stationary so as to define a stationary boundary means or surface for the mixing gap.
