摘　　要：通过实验室配水与沼液试验,探讨了Cu胁迫下电极-SBBR体系反硝化脱氮的工艺参数及其效果.结果表明,Cu胁迫电极-SBBR体系的优化参数为:水力停留时间510min,其中进水30min,厌氧30min、曝气240min、沉淀150min、排水30min、闲置30min;电流90mA,DO 3.0～4.0mg/L,C/N为8.0左右.沼液中的低质量浓度Cu(0.94mg/L)对电极-SBBR体系的胁迫作用表现不明显,电极-SBBR体系对沼液的TN,COD,Cu2+的去除率分别达到64.27%,75.46%和95.87%.A laboratory study was made, in which simulated wastewater and biogas slurry were used to in vestigate the technological parameters and effects of electrode-SBBR for denitrification affected by copper. The results showed that under copper stress the optimal conditions of the system were recommended as follows： HRT 510 min, inlet time 30 min, anaerobic time 30 rain, aeration time 240 rain, sedimentation time 150 min, drainage time 30 min, and resting time 30 rain, electric current 90 mA, DO 3.0～4.0 rag/L, and C/N ratio 8.0. Cu2＋ in the biogas slurry at a low concentration （0.94 mg/L） had no significant stress effect on the electrode-SBBR system, and the removal rates of TN, COD and Cu2＋ from the biogas slurry were as high as 64. 27%, 75. 46% and 95. 87%, respectively.
