摘要

Firstly,the water-quality characteristics of intestinal lavage wastewater and enzymolysis wastewater from the typical heparin sodium productive process were analyzed,and then the segregation treatment was applied in the treatment of enteric coating and heparin sodium manufacturing wastewater. Finally,the treatment of the two kinds of wastewater by different methods were discussed. The results showed that,COD of enzymolysis wastewater treated by centrifugation-coagulation-Fenton reagent oxidation-adsorption process was lower than 100 mg /L,while intestinal lavage wastewater treated by coagulation-ASBR-SBR process could meet the first standard of Comprehensive Discharge Standard of Sewage( GB8978-1996) after one month of continuous operation.
