摘　　要：针对印刷业油墨污水色度高、COD高、难以生化降解、通常的生化处理难以达标排放的特点,采用酸析加化学氧化工艺处理,比较了不同种类的酸、氧化剂与助凝剂组合对油墨废水COD和色度的处理效果,同时分析其经济合理性。研究结果表明:酸析—Fenton氧化工艺和酸析—次氯酸钠氧化工艺对COD去除率与脱色率均达到90%以上,均可达标排放且经济上可以接受。Printing ink wastewater are characterized by high chroma, high COD and difficult biochemical degradation. Acid separation and chemical oxidation processes have been used for its treatment. The treatment effects of different combinations of acids,oxidants and coagulant aids on the treatment of COD and chroma of printing ink wastewater are compared, and the economic rationality is analyzed. The results show that both of the COD removing rate and decoloration rate of acid separation-Fenton oxidation process and acid separation-sodium hypochlorite process can be above 90%, reaching the discharge standard and being acceptable economically.
