Abstract

Wastewater which is contaminated with resistant organic substances, particularly effluent from a pulp bleach plant, is treated in a biological purification stage (2). The resistant substances are separated from the treated wastewater, preferably by membrane filtration (13), and are retained in the biological purification stage together with the microorganisms which are active in the biodegradation process, such that they are caused to have a retention time in the biological purification stage which is substantially longer than that of the wastewater.
