<p>Method for processing of liquid manure and similar slurry materials which contain organic material as well as nitrogenous chemical substances. The method leads to the separation of the slurry material into a solid-matter phase and a liquid phase, which together contain the nitrogenous components. The degree of acidity of the slurry material is adjusted before separation. Both material phases are sterile. The liquid phase can be evaporated, and the water recovered from this process can be used for feeding purposes, while the concentrate can be combined and used together with the solid-matter phase as fertilizer. There is also described an apparatus with a separation tank (101,102) for the execution of the method. The separation tank has a discharge opening (105) for the liquid phase, a heating surface (106) connected to a heat source (107) for the heating of the pre-treated liquid manure (10), a solid-matter removal element (110, 112) and a liquid manure introduction element (118). Additionally, it can have a liquid manure pre-heating heat exchanger (108), liquid manure sieves (109), liquid manure level control (111), liquid manure temperature control (119) and a solid-matter draining element, which ensure continuous operation.</p> |
