ANAEROBIC DIGESTION METHOD OF ORGANIC WASTE HAVING HIGH SALINITY

摘要

PURPOSE: An anaerobic digestion method of organic waste having high salinity is provided to obtain sludge for compost having low density of salt by preparing an environment where an anaerobic digester is continuously survive. CONSTITUTION: An anaerobic digestion method of organic waste having high salinity comprises the steps of: injecting digested sludge into a solid/liquid separation tube(120), wherein the digested sludge is created in an anaerobic digester(110) into which an organic waste is injected; separating the digested sludge from the high liquid separation tube; re-injecting the transfer sludge obtained from the high liquid separation tube into the anaerobic digester; discharging the solid sludge to the outside when the density of salt is lowered into a certain level; and discharging the waste separated from the high liquid separation tube to an additional processing facility after judging whether or not the residual sludge can be used as the compost.
