  • 摘要: 采用铁炭微电解-Fenton联合工艺深度处理制药废水生化出水，探讨了初始pH、曝气量、反应时间等因素对微电解出水Fe2+和Fe3+变化规律、COD降解速率以及后续Fenton氧化效果的影响，为优化微电解-Fenton氧化联合工艺提出了微电解间歇加酸的理论。间歇加酸可提高微电解系统中COD降解速率和Fe2+含量，使后续Fenton氧化无需投加FeSO4·7H2O即可达到较好的COD去除效果。结果表明，当初始pH=2.5，曝气量为 0.6 m3/h，间歇加酸30 min/次，微电解反应2 h，出水投加1 mL/L的H2O2进行Fenton氧化2 h，COD总去除率可达81.33%；间歇加酸30 min/次可将微电解反应2 h出水Fe2+浓度从50 mg/L提高至151 mg/L，COD降解速率从10.6 mg COD/（L·h）提高至22.2 mg COD/（L·h）。
    Abstract: Advanced treatment of pharmaceutical wastewater biochemical effluent was studied by using ferric-carbon micro-electrolysis-Fenton combined process.Effects of initial pH,aeration rate and reaction time of micro-electrolysis on effluent Fe2+and Fe3+ concentration variation,COD degradation rate and subsequent Fenton oxidation process were discussed.Theory of adding sulfuric acid intermittently was proposed in order to optimize the combined process of micro-electrolysis-Fenton oxidation.Degradation rate of COD and Fe2+ concentration were improved by adding sulfuric acid intermittently to micro-electrolysis system,that got better COD removal rate of Fenton oxidation without adding FeSO4·7H2O.The results showed that,when initial pH=2.5,aeration rate was 0.6 m3/h,adding sulfuric acid was 30 min/time,micro-electrolysis reaction was 2 h,Fenton oxidation was 2 h by adding 1 mL/L H2O2,the effluent COD removal rate achieved 81.33%.Adding sulfuric acid 30 min/time to micro-electrolysis system could increase effluent Fe2+ concentration from 50 mg/L to 151 mg/L,COD degradation rate from 10.6 mg COD/(L·h) to 22.2 mg COD/(L·h).
