A process for the disposal of liquid manure is described, which is characterized in that the urea is hydrolyzed enzymatically in the liquid manure, if necessary mechanical pre-clarification is carried out before or after the hydrolysis, optionally the suspended and colloidally dissolved ingredients contained in the liquid manure with inorganic or organic electrolytes or polyelectrolytes or their mixtures are flocculated and / or precipitated, optionally the flocculated or precipitated colloids and solids are separated from the manure by flotation with subsequent mechanical separation of the flotate, the ammonia dissolved in the manure being removed therefrom by outgassing, whereby a residual liquid manure is obtained, if necessary a further mechanical clarification of the residual liquid manure is carried out, if necessary a neutralization of the residual liquid manure is carried out and the residual liquid manure obtained in step 5, 6 or 7 is sprinkled or it is disposed of separately in an aerobacterial manner or is fed to the denitrification stage of a sewage treatment plant or is electrodialytically split into a concentrate and a diluate, the concentrate being fed to the denitrification stage of a sewage treatment plant. |
