Resource utilization is an effective way to cope with the rapid increase of kitchen waste and excess sludge, and volatile fatty acids produced by anaerobic fermentation is an important way of recycling organic waste. However, the single substrate limits the efficient production of volatile fatty acids. In recent years, volatile fatty acids produced by anaerobic co-fermentation using different substrates has been widely studied and applied. In this paper, we analyze the characteristics of fermentation to produce acid using kitchen waste and excess sludge alone or mixture. Influences of environmental factors and microbial community structure on the type and yield of volatile fatty acids in the anaerobic fermentation system are discussed in detail. Moreover, we propose future research directions, to provide a reference for recycling kitchen waste and excess sludge.
资源利用是应对厨余垃圾和剩余污泥快速增长的有效途径，厌氧发酵产生的挥发性脂肪酸是有机废弃物资源化的重要方式。然而，单一底物限制了挥发性脂肪酸的高效生产。近年来，利用不同底物进行厌氧共发酵产生挥发性脂肪酸受到广泛研究与应用。本文分析了单独或混合使用厨余垃圾和剩余污泥进行产酸发酵的特性。详细讨论了环境因素和微生物群落结构对厌氧发酵系统中挥发性脂肪酸类型和产量的影响。此外，我们提出了未来的研究方向，为厨余垃圾和剩余污泥的资源化提供参考。
