摘要
The invention relates to a method for reducing the nutrient content of manure and poultry droppings, wherein a reduction in the content of organic dry matter by the degradation of carbon in a biogas plant is followed by an at least partial removal of nutrients from liquid fermentation residue in the biogas plant. According to the invention, the degradation of carbon in the biogas plant and the nutrient separation from the fermentation residue take place at a process temperature below 35 ° C. It is provided that the at least partial nutrient separation comprises the at least partial removal of nitrogen compounds and phosphorus and potassium compounds, the at least partial removal of the nitrogen by means of nitrification and denitrification or by means of deammonification is provided, as a result of which the nitrogen is converted to N sub 2 /sub nitrogen.
