Chondroitin Sulfate (CS) is a kind of important biochemical product. The production of CS leads to producing lots of highly concentrated organic wastewater and the COD of the water is over 100 g/L. This paper studies the post-treatment of the CS wastewater from a Shandong biochemical product plant and proves that the coagulation post-treatment can reduce the CODCr of the water out of biochemical treatment from 316 mg/L to 76 mg/L, the BOD5 from 100 mg/L to 15 mg/L. The water meets the First Grade Discharge Standard GB8978-1996.(3).
Key words: chondroitin sulfatecoagulation; wastewater; treatment
