Abstract
The invention concerns a biological method for the purification of waste water contaminated with organic carbon and nitrogen compounds, the nitrogen compounds being first nitrified in an aerobic-treatment stage (1) and then denitrified in an anaerobic treatment stage (2), preferably to molecular nitrogen. The invention proposes that at least a part of the carbon compounds is separated from the waste water [e.g. by adsorption (3)] before it enters the aerobic-treatment stage and at least a part of the separated carbon compounds (4) is added back to the waste water to be treated anaerobically in the second stage. The method proposed enables optimum conditions to be established for the microorganisms present in each of the two stages.
