| 中文摘要: |
| 采用A/O-电催化氧化法处理村镇垃圾中转站渗滤液，并针对工艺核心电催化氧化单元的相关运行参数进行探究。结果表明：使用椰壳活性炭作为粒子电极基体材料，以Sn-Sb作为活性催化剂，在初始pH值＜7、外加电压15 V条件下，电解中转站垃圾渗滤液效果较好；联合工艺连续运行阶段，当水力停留时间达到11 d时，原水COD从（31 098±1 270）mg/L下降到（391±44）mg/L，渗滤液可生化性（B/C）从0.336±0.020提升到0.719±0.024，可生化性显著增强。 |

| The process of A/O electrocatalytic oxidation was used to treat the leachate from village garbage transfer station，the operating parameters of its technological core were studied. The results showed that good treatment effect was achieved by employing coconut shell activated carbon as the substrate material of particle electrode, Sn Sb as the active catalyst，and under the conditions of the initial pH value was less than 7 and the applied voltage was 15 V. In the continuous operation of the process, when hydraulic residence time reached 11 d，COD concentration of raw water decreased from （31 098±1 270）mg/L to （391±44）mg/L, the biodegradability (B/C ratio) of the landfill leachate increased significantly from 0.336±0.020 to 0.719±0.024. |
