摘要:針對四環素類抗生素（TCs）生產廢水在生物處理過程中普遍存在的泡沫劇烈、污泥沉降困難、處理效率低等問題，提出了生物曝氣—鐵鹽混凝預處理工藝。結果顯示，生物預處理工藝既可以提高TCs去除率，又能夠降低鐵鹽投加量，當鐵鹽投加量（以Fe計）為100 mg/L時，TCs去除率由27.5%提高到84.5%；對于未經生物預處理的廢水，若要達到相同的TCs去除效果，鐵鹽投加量為600 mg/L。這可能是由于廢水中77.8%的揮發性脂肪酸在生物預處理過程中被有效去除，從而降低了其對鐵鹽混凝去除TCs的干擾。經過生物預處理后，后續生物處理系統出水COD由531 mg/L降至199 mg/L，處理效果提升明顯。

Abstract:The biological treatment of tetracyclines (TCs) antibiotic production wastewater has the common problems such as large amount of foam, difficulty in sludge settlement and low treatment efficiency. To solve these problems, a pretreatment process consisting of biological aeration and iron salt coagulation was proposed. The biological pretreatment not only increased the TCs removal rate, but also reduced the dosage of iron salt. When the dosage of iron salt (calculated by Fe) was 100 mg/L, the TCs removal rate increased from 27.5% to 84.5%. To achieve the same TCs removal performance for wastewater without biological pretreatment, the dosage of iron salt was 600 mg/L. The reason might be due to the fact that 77.8% of volatile fatty acids in wastewater were effectively removed during the biological pretreatment process, thus reducing their interference to the removal of TCs by ferric coagulation. After the biological pretreatment, the COD in the effluent from the subsequent biological treatment system decreased from 531 mg/L to 199 mg/L, and the treatment performance was significantly improved.
