There is provided a method for highly treating distillation waste generated in the process of separating a distilled alcoholic material after alcoholic fermentation of starchy materials. The method includes the steps of adding sodium polyacrylate to the distillation waste from the starchy materials, then adding chitosan to treat the distillation waste, and further adding sodium polyacrylate to the waste. Furthermore, solid-liquid separation is then carried out. A liquid material thus separated is brought into contact with a reverse osmosis membrane.

Method for treatment of distillation waste from starchy materials

A process for producing hydrogen peroxide by subjecting a working solution containing anthraquinones as the reaction medium, to reduction and oxidation alternately, which process is characterized in that (1) the anthraquinones as the reaction medium contained in the working solution are a mixture of an alkyl-substituted anthraquinone and an alkyl-substituted tetrahydroanthraquinone, (2) in the reduction step, the total amount of the alkyl-substituted tetrahydroanthraquinone in the working solution and part or the total amount of the alkyl-substituted anthraquinone in the working solution are reduced, and (3) in the working solution after the reduction step, the content of the alkyl-substituted anthrahydroquinone formed is kept higher than the content of the alkyl-substituted tetrahydroanthrahydroquinone formed.
