| Abstract: | There are starch,pigment and pectin in the waste water of extracting sodium aescinate.Sodium aescinate in the extractant is easy to form foam and difficult to be reclaimed and treated.The concentration of synthetic waste water was reduced by foam inhibitor(YP-1),and was used to treat and recover residual effluent,thus reducing the concentration of the synthetic wastewater.The COD_ Cr of effluent was less than 100 g/L,which could meet the national discharge standard by three hours treatment of hydrolytic acidification and six hours treatment of aerobic biotreatment. |

| Keywords: | waste water of sodium aescinate hydrolytic acidification and treatment of waste water |
