METHOD FOR CONTINUOUS BIOLOGICAL DEGRADATION, METHOD FOR ANAEROBIC BIOLOGICAL DEGRADATION AND CONTINUOUS METHANOGEN, AND BIOLOGICAL FILTER FOR USE IN TREATING WASTEWATER

摘要

THE INVENTION RELATES TO A BIOLOGICAL FILTER WHERE POLLUTANTS IN WASTEWATER CAN BE BIOLOGICALLY DEGRADED BY A BIOMASS OF MICRO-ORGANISMS ON THE SURFACE OF A PADDING. /P P ACCORDING TO THE INVENTION A SEALED CONTAINER 13 CONTAINS THE PADDING 14, AND THE WASTEWATER IN 10, MIXED WITH A RECYCLING LIQUID IN 11, MAY DRAIN DOWN THROUGH THE PACKING, IN COUNTER-CURRENT WITH THE ASCENDING GAS. /P P THE INVENTION APPLIES IN PARTICULAR TO BIOLOGICAL DEGRADATION WITH OR WITHOUT METHANE PRODUCTION.
