Abstract

PURPOSE:To treat waste liquid of alcohol distillation at a low cost by subjecting the waste liquid to an anaerobic biotreatment and further to an aerobic biotreatment, then adding and mixing an inorg. flocculating agent to and with the waste liquid under an acidic condition. CONSTITUTION:The waste liquid of the alcohol distillation is subjected to the anaerobic biotreatment, then to the aerobic biotreatment. Sulfuric acid, hydrochloric acid, etc., are added to the treated liquid to adjust the liquid to an acid liquid; thereafter, the inorg. flocculating agent such as aluminum sulfate, ferric sulfate or ferric chloride is added and mixed to and with the liquid. This liquid is separated to sludge and treated liquid by a solid-liquid sepn. The ratio of the flocculating agent is thereby extremely lowered and the amt. of the SS to be generated is decreased.
