METHOD FOR DEODIRIZING AND DECONTAMINATING BIOLOGICALLY CONTAMINATED SLUDGE

摘要

The present invention relates to an environmently friendly method for deodorizing and rendering innocuous biologically contaminated sludge or slurry - primarily municipal wastewater sludge or liquid manure - containing up to 10% of solid matter with aerobic stabilization. The method comprises adding adsorbent carbonaceous mineral material having a particle size of less than or equal to 5 mm to the sludge or slurry and processing the obtained mixture by wet grinding to form a stable suspension in such a way that the solid content of the mixture is ground to particles having a particle size of less than 200 µm and the living organisms are lysed.
