摘　　要：直接种间电子传递(DIET)是近年来发现的一种微生物电子传递方式,其在废水厌氧生物处理的重要过程中起重要作用。提高DIET效率能在促进有机物厌氧降解产甲烷的同时储存更多能量,优化厌氧生物处理工艺性能并降低处理成本。本文在DIET过程特性分析的基础上,重点论述了活性炭、生物炭、碳纤维布、单壁碳纳米管4种碳材料对废水生物处理中DIET过程的促进作用,并对今后的研究方向进行了展望。Direct interspecies electron transfer （DIET） as a kind of microbial electron transfer mode found in recent years, plays an important role in anaerobic wastewater treatment. The increasing of DIET efficiency could promote the organic matter degradation and methane production with more energy storage and then the performance of anaerobic biological treatment reactor could be optimized and the treatment cost could be reduced. Based on the characteristics analysis of DIET, the effects of 4 carbon materials, such as activated carbon, biochar, carbon fiber and single-wall carbon nanotube, on improvement of DIET in wastewater treatment process were discussed. The directions for future research were prospected.
