Abstract
PURPOSE: To remove lignin effectively and economically by adding an excess of a nitrogen cpd. to liquor to be treated and aerating the cpd.-added liquor to remove lignin biologically.
CONSTITUTION: In treatment of lignin-contg. waste water with activated sludge, after adding a nitrogen cpd. in excess of the amt. required to remove BOD the water is aerated. As the nitrogen cpd. an inorg. cpd. such as urea, ammonia or a salt thereof or an org. nitrogen cpd. such as protein is pref. used, and the aeration is pref. performed until the nitrogen cpd. is nitrified by oxidation.
