Abstract:

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

摘要：

硫酸软骨素生产过程中产生了大量的高浓度有机废水,COD高达100g/L。以山东某生化制品有限公司硫酸软骨素废水为对象,对其后处理进行了研究。结果表明,后处理采用混凝处理工艺,可使生化处理后废水的COD_Cr从316mg/L降至76mg/L,BOD₅从100mg/L降至15mg/L,出水达到了GB8978-1996一级排放标准。
