随着城市化进程的加快和城市污水处理的推进，城市污水污泥量显著增加。考虑到正在出现的全球能源危机和日益增长的环境保护需求，氢是一种很有前途的清洁燃料。污泥厌氧发酵制氢技术是一种经济、环保的可持续发展技术。因此，本文对污泥制氢的机理进行了综述和阐述。对污泥预处理及影响制氢的关键因素进行了研究。一些挑战仍然存在，例如几乎所有的研究都是在批培养中进行的实验，氢气产量并不大。在这一领域需要进一步的研究，如抑制耗氢细菌，培养和筛选高效细菌。厌氧共消化制氢的机理、影响因素及技术经济评价有待进一步研究。
The amount of sewage sludge has increased remarkably with the acceleration of urbanization and the promotion of municipal wastewater treatment. Hydrogen is a promising clean fuel, considering the emerging global energy crisis and the growing demand for environmental protection. Producing hydrogen from sewage sludge through anaerobic fermentation is an economical and environmentally sustainable technology. Therefore, in this work, the mechanism of hydrogen production from sludge is critically reviewed and clarified. Current researches including sludge pretreatment and key factors affecting hydrogen production were investigated as well. Some challenges still remain, such as almost all studies feature experiments in batch cultures, and the hydrogen yields were not large. Further studies are needed in this arena, such as inhibiting hydrogen‐consuming bacteria, culturing, and screening high‐efficiency bacteria. The mechanism of hydrogen production from anaerobic co‐digestion, their factors, and techno‐economic evaluation need be further studied as well.
