The invention relates to a new method for treating bottom boiler water, belonging to the technical field of making wine. The technical problem to be solved is to provide a method for treating bottom boiler water. The method comprises the following steps of: filtering the bottom boiler water through a filter screen, wherein the filter residues are vinasse which can be sold as a feed after being dried; causing the filtrate after filtering to flow into a settling tank and a liquid collecting tank, standing so that vinasse mud is settled, wherein the settled vinasse mud is sold as a fertilizer; adding the settled bottom boiler water supernatant to an aroma extracting distiller by a pump for distillation; condensing the distillate through a condenser to obtain a wine mixing aromatic fluid which is stored and then proportionally mixed into wine; and then collecting a high-concentration vinasse suspended matter left in distillation and pumping the matter to a boiler for burning with coal. The method, at low investment, is capable of not only solving the environmental pollution problem, but also effectively utilizing the fermented aroma matters, thereby changing waste materials into tingsof value; therefore, multiple purposes can be achieved; and zero discharge of the bottom boiler water can be realized.
