PROBLEM TO BE SOLVED: To provide a method for treating brewery wastewater by which the load to be applied to an activated sludge tank can be decreased when the brewery wastewater to be generated at a step of brewing Shochu, Sake or the like, particularly, unrefined Sake lees are dehydrated by a dehydrator and treated in the activated sludge tank. SOLUTION: The method for treating brewery wastewater comprises the steps of: adding a silica-iron-based inorganic flocculant to brewery waste water; adding an organic polymer flocculant to the inorganic flocculant-added brewery waste water; and subjecting the organic polymer flocculant-added brewery wastewater to solid-liquid separation treatment.
