The invention discloses a method for hydrolyzing the straw with glucurolactone production waste liquid for fermenting the alcohol with yeast in the industry waste water biological treatment field. The invention applies the effective treatment and recovering method, which doesn't have the bibliographical information in china. The invention is characterized by the following: hydrolyzing the straw with strong acid of glucurolactone production waste liquid; treating the hydrolyzing liquid by adding Ca (oH)2 or Cao; centrifuging and removing the deposit; adding the liquid as the unique carbon source or the nutrient; fermenting the alcohol with yeast. The invention achieves the treatment of glucurolactone production waste liquid, which recovers the acid of the waste liquid and the sugar substance in the waste liquid, and protects the environment and the resources.
