Abstract

Esta invención se refiere a un método para tratar flujos de líquidos en fábricas de pulpa química, que comprende una unidad de preparación de pulpa m arrón (20), una unidad de blanqueo (30), una seca dora de pulpa (80) y una planta de tratamiento de aguas residuales (50). El método comprende conduc ir al menos parte del agua blanca que proviene de la secadora de pulpa (80) a la unidad de desligni ficación con oxígeno (25). La invención se refiere además a un sistema para tratar flujos de líquid os en fábricas de pulpa química, y al uso de agua blanca como agua de dilución en la unidad de desl ignificación de oxígeno (25).This invention relates to a method for treating liquid flows in chemical pulp factories, which comprises a marine pulp preparation unit (20), a bleaching unit (30), a dry pulp mill (80) and a sewage treatment plant (50). The method comprises driving at least part of the white water that comes from the pulp dryer (80) to the oxygen delignification unit (25). The invention further relates to a system for treating liquid flows in chemical pulp factories, and to the use of white water as dilution water in the oxygen ignition slider unit (25).
