摘要

LIQUID MANURE IS SEPARATED IN A PASSIVE PHASE AND A WATER PHASE THROUGH A METHOD IN WHICH MANURE IN A FIRST TREATMENT STEP IS SEDIMENTED IN A PASSIVE PHASE CONTAINING THE COARSE MATERIALS COMPONENTS OF A LIQUID AND LIQUID MANURE. , WHICH IS FILTERED AND DISCHARGED AS A WATER PHASE WITH A VERY HIGH N CONTENT, WHEN DESIRED, OR, IT IS PASSED TO A SECOND TREATMENT STEP IN WHICH IT IS MIXED WITH A FLOCULANT AND IT IS FLOCULATED AND SEDIMENTED IN A PASSIVE PHASE SECONDARY, WHICH JOINS WITH THE PASTA PHASE FORMED IN THE FIRST STEP OF TREATMENT, AND A SECONDARY AQUEOUS PHASE, WHICH IS DOWNLOADED AS A WATER PHASE WITH A MODERATE N CONTENT. WHEN DESIRED, OR PASSED ON TO A THIRD TREATMENT STEP IN WHICH IT IS EXPOSED TO ION EXCHANGE WITH A CATION EXCHANGER AND IS DISCHARGED AS A WATER PHASE WITH A LOW N CONTENT. THE PASTA PHASE IS DOWNLOADED FROM THE FIRST SEDIMENTATION STEP.
