Purins denitrogenation with degradation of organic matter consists of solids separation lime, addition, settling, ammonia absorption, and sludge calcination

摘要

The purins denitrogenation with degradation of organic matter comprises separation of the solids, application of lime, two-phase settling and desorption of the ammonia in an air supply tower. The ammonia is then absorbed in a second tower by sulphuric acid, for degradation in a fluidised-bed anaerobic reactor. EMBODIMENT - The degradation is completed by using the biogas generated, in calcination of the settling sludge of the treated purins.
