膜分离技术深度处理抗生素废水的研究

STUDY ON TREATING FERMENTATION WASTEWATER FROM ANTIBIOTIC PRODUCT

针对抗生素废水,采用双膜法进行处理,处理之后的出水达到回用水的目的。过程对进膜前絮凝沉降工艺、陶瓷膜超滤工艺以及反渗透出水进行了研究。结果表明,在加入350 mg/L PAFC絮凝后,采用恒流量陶瓷膜操作工艺,经过反渗透过滤,出水COD能降到50 mg/L以下,电导率降到50 uS/cm以下,浊度降到0.2 NTU以下。

Fermentation wastewater from antibiotic product was treated with double-membrane filtration to be reused. The technology of flocculate sedimentation, ultrafiltration with ceramic membrane, and RO were discussed. Result show that： after flocculation with 350 mg/L PAFC, using constant flow operation of ceramic membrane, the waster water was treated to the extent of reuse water standard by RO： COD ≤50 mg/L, conductivity ≤50 μS/cm, turbidity ≤0.2 NTU.
