摘要： The invention relates to a method for the purification of effluent, in particular, effluent from the paper industry, comprising the following method steps: a) aerobic purification of the effluent using activated sludge in an activated sludge tank (1), b) settling of at least a part of the effluent/activated sludge mixture exiting the activated sludge tank (1) in a settling tank (2), c) separation of a part of the effluent/activated sludge mixture exiting the settling tank in a separating device (3) and d) recycling of at least a part of the activated sludge separated off in steps b) and/or c) into the activated sludge tank (1).

摘要： The invention relates to a method for purifying wastewaters, particularly wastewaters produced in the paper industry, involving the following steps: a) aerobic clarification of the wastewater using activated sludge in an activation stage; b) carrying out, in a secondary settling tank, a subsequent clarification of a portion of the wastewater/activated sludge mixture leaving the activation stage; c) desiccating, in a desiccation unit, another portion of the wastewater/activated sludge mixture leaving the activation stage; d) returning at least a portion of the activated sludge removed in steps b) and c) into the activated sludge tank.
