Biogas generation using food waste anaerobic co-digestion with activated sludge provides a cleaner addressable system, an excellent solution to global challenges, the increasing energy demands, fuel charges, pollution and wastewater treatment. Regardless of the anaerobic digestate end product values, the technology lacks efficiency and process instability due to substrate irregularities. Process parameters and substrate composition, play a vital role in the efficiency and outcome of the system. Intrinsic biochar properties such as pore size, specific surface properties and cation exchange capacity make it an ideal additive that enriches microbial functions and enhances anaerobic digestion. The pretreatment and co-digestion of food waste and activated sludge are found to be significant for efficient biogas generation. The advantages, drawbacks, limitations, and technical improvements are covered extensively in the present review besides the recent advancement in the anaerobic digestion system.
利用活性污泥进行食物垃圾的厌氧共消化来产生沼气，提供了一种更清洁的可寻址系统，是解决全球挑战、日益增长的能源需求、燃料费用、污染和废水处理问题的绝佳方案。无论厌氧消化物的最终产品价值如何，由于基质的不规则性，该技术都缺乏效率和过程稳定性。工艺参数和基质组成对系统的效率和结果起着至关重要的作用。内在生物炭的特性，如孔径、比表面积和阳离子交换能力，使它成为一种理想的添加剂，可以丰富微生物的功能，增强厌氧消化。本综述除了介绍厌氧消化系统的最新进展外，还广泛涵盖了预处理和食物垃圾与活性污泥的共消化对高效沼气生成的重要性。
