摘要
采用自行优化设计的膜生物反应器(MBR)对含7-ACA的抗生素废水进行试验研究,主要考察了不同进水7-ACA值下,MBR对含7-ACA的抗生素废水的处理效果。结果表明:在试验运行稳定后的前30 d,当进水7-ACA值<60 mg/L时,出水COD值始终低于120 mg/L,其平均去除率达到93.7%;出水BOD5值维持在30 mg/L以下,出水水质达到《化学合成类制药工业水污染物排放标准(》GB 21904—2008)的要求。采用多元线性回归方法,以7-ACA负荷和进水7-ACA值为自变量,以对7-ACA和COD的去除率为因变量建立数学模型,该模型能较好地反映上述变量间的关系,可为工程实践提供理论指导。
An optimized membrane bioreactor （MBR） was employed to treat the antibiotic wastewater containing 7-ACA. The treatment efficiency of this wastewater in MBR with different concentrations of 7-ACA was investigated. The results demonstrate that in the first 30 d after the stable operation, when the 7-ACA concentration is less than 60 mg/L, the effluent COD is below 120 mg/L, the average COD removal rate is 93.7%, and the effluent BOD5 is less than 30 mg/L. The effluent quality meets the Discharge Standards of Water Pollutants for Pharmaceutical Industry Chemical Synthesis Products Category （GB 21904 -2008 ）. By means of multi-variable linear regression method, taking 7-ACA load and influent values as independent variables, the removal rates of 7-ACA and COD as dependent variables, a mathematical model was constructed. The model can reveal the intrinsic relationship between these parameters and provide theoretical instruction in applications.
