Abstract
The invention relates to a improved process for the biological transformation of phosphorus and nitrogen containing animal waste excrement into ecologically manageable materials by a process wherein solids in an aqueous slurry of the excrement are precipitated in a solids ecoreactor, the treated slurry is passed to a bioreactor zone where it is soluble phosphorus is precipitated with metallic salts, the slurry is aerobically and anaerobically treated to form an active biomass that actively bioconverts remaining soluble phosphorus and the aqueous slurry containing bioconverted phosphorus is passed to a polishing ecoreactor zone wherein the at least a portion of slurry is bioconverted to a beneficial humus material.
