PROCESS FOR TREATING A CURRENT WATER FROM ORGANIC RESIDUAL WATER WITH CONCOMITANT PRODUCTION OF METHANE GAS IN AN ANAEROBIC REACTOR

摘要

THE INVENTION CONCERNS A PROCESS FOR THE TREATMENT OF WASTE WATER WITH METHANE PRODUCTION, IN AN ANAEROBIC REACTOR INCLUDING A CONTAINER CONTAINING A BED MIXED WITH METHANOGENOUS BACTERIA AGGLOMERATED SO THAT IT IS SENSITIVELY RETAINED IN THE REMAINING CONTAINER. . /P P ACCORDING TO THE INVENTION, THE METHANE PRODUCTION RATE IS CONTINUOUSLY MEASURED AND THE COD SUPPLY RATE IS CONTINUALLY VARIED TO MAINTAIN A PREDETERMINED RELATIONSHIP BETWEEN THESE RATES, CO CORRESPONDING TO THE FEED RATE BEING GREATER THAN CL CORRESPONDING TO THE RATE OF METHANE PRODUCTION. A FILTER 5, A RECYCLING HEATER 26, A SUPPLY TANK 7 WITH PUMP 8, AND A MICROCALCULATOR 49. /P P THE INVENTION APPLIES IN PARTICULAR TO THE TREATMENT OF INDUSTRIAL WATER.
