摘要
PROBLEM TO BE SOLVED: To provide a solid-liquid separation method in a membrane separation activated sludge apparatus by the addition of a water-soluble polymer and an inorganic flocculant to an activated sludge-treated water in order to stably suppress the rise of transmembrane pressure difference.SOLUTION: Provided is a solid-liquid separation method by membrane separation activated sludge treatment. In the method, a cationic polymer comprising an amidine structural unit and an inorganic flocculant comprising a polyvalent anion are added to the activated sludge.SELECTED DRAWING: None
