METHOD AND FACILITY FOR BACTERIAL PROCESSING OF INDUSTRIAL REJECTS, AND METHOD FOR ESTABLISHING A POPULATION OF ANAEROBIC BACTERIA IN THE SAME

摘要

THE PRESENT INVENTION CONCERNS A PROCESS, A PLANT FOR THE ANAEROBIC BACTERIAL DEGRADATION OF ORGANIC PRODUCTS CONTAINED IN AQUEOUS DISCHARGE. /P P THE ANAEROBIC BACTERIAL DEGRADATION PROCESS CONSISTS OF INTRODUCING AN AQUEOUS MEDIUM IN A REACTOR 12, IN CONTACT. PUMP 15, 16 THE AQUEOUS MEDIUM INTO A REACTOR 10 WITH A FLUIDIZED BED 11, THERE ARE REACTOR 10 HAVING AN EFFECTIVE VOLUME NOT GREATER THAN 0.35 TIMES THE EFFECTIVE VOLUME OF CONTACT REACTOR 12 AND CONTAINS A BED 11 OF FINELY DIVIDED INERT SOLIDS WHICH SUPPORTS A POPULATION OF BACTERIA IN MAJOR PARTY ANAEROBIC, TO KEEP BED 11 IN A FLUIDIZED STATE, TO RECYCLE THE AQUEOUS MEDIUM WHICH HAS CROSSED THE REACTOR 10 A FLUIDIZED BED OR AT LEAST PART OF IT TO THE CONTACT REACTORS 12 AND MANY CONTINUOUS OR DISCONTINUOUS SUPPLY THE TREATED EFFLUENT FROM THE FLUIDIZED BED REACTOR OR THE CONTACT REACTOR. /P P THE PRESENT INVENTION APPLIES IN PARTICULAR TO THE TREATMENT OF INDUSTRY WASTE LS.
