| 摘 要： | 采用水解酸化与Fenton试剂分别处理高浓度抗生素化学合成废水的厌氧出水,并采用MBR验证其生化性的改善。试验表明:在废水ρ(COD)平均为4 084 mg/L时,水解酸化COD去除率平均为26.2%,ρ(BOD5)/ρ(COD)从0.23提高到0.31,但无法保证MBR出水ρ(COD)<120 mg/L。Fenton试剂反应条件为:ρ(H2O2)=5 000 mg/L,ρ(Fe2+)=4 000 mg/L,pH=7,反应时间1 h,COD去除率达50%。混合废水经MBR处理后,出水ρ(COD)平均为98.4 mg/L,可稳定达《制药工业水污染物排放标准》。 |

| Abstract: | Hydrolytic acidification and Fenton's reagent were applied to treat anaerobic discharged wastewater of chemical synthesis-based antibiotic wastewater respectively,and then MBR was used for testifying the effectiveness of biodegradability improvement.The results showed: when the average COD of wastewater was 4084mg/L,the average COD removal rate was 26.2% for hydrolytic acidification,and BOD5/COD was increased from 0.23 to 0.31.But it can't guaranteed that COD of discharge was below 120 mg/L.The optimized operation condition for Fenton's reagent was ρ(H2O2)=5 000 mg/L,ρ(Fe2+)=4 000 mg/L,pH=7,reaction time=1h,COD removal rate was 50%.After the mixed wastewater was disposed by MBR,the average COD of effluent was 98.4 mg/L,which could meet the requirement of "Pischarge Standard of Pharmaceutical Wastewater Pollutants". |
