摘　　要：厌氧消化是一种非常有用的废物处理方式,既能实现污染控制,又可回收能源。在一些废物中常含有大量的含硫物质,这些物质是导致厌氧消化不稳定和运行失败的重要原因。总结了厌氧消化工艺硫抑制的研究进展,探讨了硫抑制的机制和控制因子,并在此基础上提出了硫抑制调控对策。Anaerobic digestion is an attractive waste treatment practice in which both pollution control and energy recovery can be achieved. A wide variety of inhibitory substances, including sulfide are the primary cause of anaerobic digester upset or failure since they are present in substantial concentration in wastes. The research progress in the sulfate inhibition from anaerobic processes is summarized, the mechanism and the controlling factors of sulfate inhibition are discussed. Accordingly, the methods to moderate the sulfate inhibition are introduced.
