METHOD FOR TREATING THE WASTE LIQUER RESULTED FROM ETHANOL PRODUCTION THROUGH CASSAVA FERMENTATION

摘要

A method for treating the waste liquor resulted from ethanol production through cassava fermentation is provided The method comprises the steps of (1) introducing water-soluble ester of alginic acid and/or water-soluble salt of alginic acid into the waste liquor, and subjecting the waste liquor to solid-liquid separation to obtain solid production and liquid production, and (2) subjecting the liquid production obtained in step (1) to the waste water treatment The method can significantly reduce the time for solid-liquid separation, and enormously increase the treatment capacity of waste liquor in unit time without adding extra equipments, thereby, the method resolves the technical difficulty resulting in low load of the equipments used in producing ethanol through cassava fermentation, and enormously increase the production capacity of the equipments for producing ethanol.
