Abstract:

研究电-Fenton法预处理青霉素钠(penicillinGsodium,PGN)模拟废水的降解规律,分析预处理过程中PGN浓度、COD、TOC的变化情况及BOD5/COD改善情况。当T=20℃、pH=3时,投加0.5g/LFeSO4、0.2mL/LH2O2,于0.3A电流下降解浓度为100mg/L的PGN废水,120min后PGN去除97.9%,COD去除76.7%,TOC去除59.8%,BOD5/COD由0升至0.4,有效提高了废水的可生化性。以红外光谱(infraredspectrogram,IR)和液相色谱质谱联用(LiquidchromatogramMasschromatogram,LC-MS)检测青霉素钠的降解产物,说明青霉素钠抑菌的关键结构b-内酰胺环被破坏,抗菌性消失,有助于生物处理有效去除。
