Abstract

A system for efficiently treating a wastewater which contains suspended organic substances in a high concentration, the system being equipped with: a suspended-organic-substance separator (10) which separates the suspended organic substances from the water to be treated; an anaerobic sludge digester (20) which anaerobically digests the suspended organic substances separated by the suspended-organic-substance separator (10); a device (30) for conversion into nitrous acid , the device (30) oxidizing the ammonia contained in the digested liquid from the anaerobic sludge digester (20) into nitrous acid under aerobic conditions; an autotrophic denitrification device (40) whereby the ammonia contained in the treated liquid from the device (30) for conversion into nitrous acid is oxidized into nitrogen gas under anaerobic conditions with an autotrophic denitrifying microorganism; and a first transfer route (R1) through which the separated liquid from which the suspended organic substances have been removed in the suspended-organic-substance separator (10) is supplied to the device (30) for conversion into nitrous acid.
