摘　　要：餐厨垃圾中有机物及水含量高,可生化性强,其厌氧消化既可减少环境污染,又可以沼气等形式回收生物质能。但餐厨垃圾C/N值及含油、含盐量高,单独厌氧消化易出现酸化及系统不稳定等问题。然而,餐厨垃圾的联合厌氧消化可根据不同物料的特性,有效提高系统稳定性及产气效率,并促进废物资源化。该研究分析了餐厨垃圾的特征,总结了餐厨垃圾与其他有机垃圾联合厌氧消化的常见类别,分析了相关影响因素,并指出了还需解决的问题及发展方向。Food waste （FW） is easy to be biodegraded due to its high contents of organics and water. Anaerobic digestion has been proved efficient in the treatment of food waste, from the points of both pollution reduction and bio-energy recovery. However, with high C/N ratio and high contents of oil and salt, acidification and unstable operation could easily occur during anaerobic digestion processes of FW. As a result, anaerobic co-digestion, of FW with other organic wastes is getting popular these days, as it can help to avoid these problems. Here an overview about common types of anaerobic co-digestion related to FW is presented, and also analyzes factors which have impact on the co-digestion processes. It also gives suggestions on the problem needed to be addressed and direction of future research.
