  • 摘要: 研究电-Fenton法预处理青霉素钠 (penicillin G sodium, 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0.5 g/L FeSO4、0.2 mL/L H2O2，于0.3 A电流下降解浓度为100 mg/L的PGN废水，120 min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(infrared spectrogram, IR)和液相色谱质谱联用(Liquid chromatogramMass chromatogram, 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。
    Abstract: The degradation rule of pretreatment of penicillin G sodium (PGN) simulate wastewater by electro-Fenton has been investigated. Trials were performed in a batch reactor, aiming at both analyzing the decrease of PGN concentration, COD, TOC and the enhancement of BOD5/COD. Operating at T=20 ℃,pH=3, ［FeSO4］=0.5 g/L,［H2O2］=0.2 mL/L, ［PGN］=100 mg/L and electric current=0.3 A, about 97.9% of PGN, 76.7% of COD, 59.8% of TOC were removed and an increase of the BOD5/COD ratio from 0 to 0.4 was achieved after 120 min. The detection of PGN degradation products was based on infrared spectrogram (IR) and liquid chromatography-tandem mass spectrometry (LC-MS), the result showed that the b-lactam cyclic of PGN was broken and PGN could be degraded by biological treatment after oxidation on electro-Fenton as it lost the antiseptic ability
