摘要
以废水厌氧生物处理为典型的各类沼气工程,能够有效推动有机废弃物资源化、无害化、稳定化利用进程,在环境保护、能源利用方面具有显著的优越性。目前国内外研究较多的厌氧生物处理技术,主要针对城市污水、畜禽养殖场废水、医院医药废水残留、农村校园厕所粪污等。文章针对抗生素、酚类、重金属离子、苯及硫酸盐等典型抑制性物质的特性,系统性地讨论了各类抑制源在厌氧消化过程中的抑制作用机理,并针对性地提出了几类有机废水厌氧生物处理工程的解抑复稳方案,为该领域抑制源的深化研究提供一定的参考。
At present, the anaerobic technologies were mainly for treatment of urban sewage, livestock and poultry farm wastes, hospital waste, human manures, and etc. These materials contain certain kind of toxics including antibiotics, phe- nol, heavy metals, benzene and sulfate, which could cause the inhibitions for the anaerobic treatment. This paper analyzed the inhibition characteristics of these toxic materials, discussed their inhibition mechanisms. And some countermeasures were introduced to remove the inhibitions for several kind of anaerobic wastewater treatment.
