FIELD: technological processes.
SUBSTANCE: method of processing liquid flows on a pulp mill, wherein the device includes: a cooking process for producing cellulose pulp, at least one washing stage for washing the cellulose pulp, at least one bleaching stage for cellulose pulp bleaching, a sewage treatment plant, a water treatment plant and wood preparation unit. The method includes: separating process waters with low chloride content having a chloride content of less than 200 mg/l, for at least two flows according to their COC (chemical oxygen consumption), directing at least part of process waters with a low chloride content to the pulp mill to be re-used as process water.
EFFECT: improvement of the method.
