| 摘要: |
| 针对常规污水处理工艺对城市污水中以布洛芬为代表的难降解PPCPs类有机物降解效能较弱、结构复杂和活化能高等问题,构建三维电催化曝气生物滤池(TDE-BAF),并用其处理城市污水中以布洛芬为代表的难处理PPCPs类有机污染物.结果表明:TDE-BAF对布洛芬的去除效能明显比BAF高,在水温(21.14±0.05)℃、COD( 86.82±3.40)mg/L、TOC(27.56±1.08)mg/L、布洛芬(93.2±5.16)μg/L、氨氮(18.75±2.39)mg/L条件下,布洛芬出水质量浓度分别为2.28~9.32 μg/L、57.70~77.12 μg/L,平均去除率分别为93.48%和31.89%,比单独BAF布洛芬去除率提高了61.59%；TDE-BAF反应器对布洛芬的去除主要集中在TDE（T5-T6）区域,布洛芬的去除率达51.78%,占总去除率的55.40%.TDE-BAF系统降解布洛芬的作用机制主要是在同一个反应器内通过内循环,发挥了三维电催化和曝气生物滤池协同作用. |

| Abstract: |
| For conventional wastewater treatment process, the pharmaceutical and personal care products (PPCPs) represented by ibuprofen in municipal wastewater have problems such as weak degradation efficiency, complex structure, and high activation energy. Therefore, based on the internal operational characteristics of biological aerated filter (BAF) and three dimensional electrocatalysis (TDE), a TDE-BAF was constructed to treat ibuprofen in municipal wastewater. Test results revealed that the ibuprofen removal efficiency of TDE-BAF was higher than that of BAF. With water temperature of (21.14±0.05) ℃, COD of (86.82±3.40) mg/L, TOC of (27.56±1.08) mg/L, ibuprofen of (93.2±5.16) μg/L, and ammonia nitrogen of (18.75±2.39) mg/L, the effluent concentrations of ibuprofen were 2.28-9.32 and 57.70-77.12 μg/L, and the average removal rates were 93.48% and 31.89%, which was 61.59% higher than BAF treatment. The removal of ibuprofen by TDE-BAE was mainly in the TDE area (T5-T6), and the removal rate reached 51.78%, accounting for 55.40% of the total removal rate. The mechanism of TDE-BAF degradation of ibuprofen is mainly through the synergistic effect of the TDE and the BAF. |
