Summary:The invention discloses a method for culturing high-density oil microalgae to treat yeast industrial wastewater. The method comprises the following steps of: carrying out clean pre-treatment on wastewater obtained by producing yeast; then adding reducing sugar and nutritive salts to prepare a culture medium; sterilizing, inoculating and fermenting; and discontinuously feeding materials, and carrying out heterotrophism culture, so as to obtain energy microalgae with the cell density of 41.26-50.83g/L and the oil content of 40.86-45.26%. According to the method disclosed by the invention, a novel efficient and economical way which combines recycled utilization and energy-form production of industrial organic wastewater discharged in a yeast industrial production process is realized, so that the damages of the organic wastewater to the environment is reduced, and good economic benefits and social benefits are obtained.
