PROCESS AND PLANT FOR DEODORIZATION AND TRANSFORMATION INTO FERTILIZER OF PIG MANURE

摘要

The invention relates to a method and an installation for treating the slurry of procs. /P P After a first tank 3 for mixing the slurry with a limestone amendment, a double tank 4 is used for settling for four days after which the whole is sent by a pump 5 with a floating suction head 6 to a separator 8 having a 500 micron mesh passage sieve; then the liquid is sent to a basin 11, covered in transparent material 15 with evaporation openings 17, where the liquid is oxygenated by pressurized air. /P P The invention makes it possible to treat pig slurry and similar slurry to obtain a liquid and a low-odor solid which can be used as fertilizer.
