摘　　要：焦化废水是一种氨氮和有机物浓度较高的难生化降解的有机废水,作者系统地介绍了近年来国内外在焦化废水生物处理技术方面的研究进展,对最近开发的短程硝化反硝化、同时硝化反硝化以及厌氧氨氧化等生物脱氮的新理论和新工艺进行了简单的综述和讨论,并指出了这些新技术的特点和研究开发应用前景。Coking wastewater is refractory and organic,having highly concentrated ammonia-nitrogen and organisms. The advances in biological techniques for treating wastewater from coking plants in the world are analyzed. The recently developed new theories and technological of biological denitrification, such as the investigation on shortcut nitrification denitrification, simultaneous nitrification denitrification（SND） as well as anaerobic ammonium-nitrogen oxidation ,are simply reviewed and discussed. The advantages of these new technologies are compared with the traditional nitrification and denitrification technologies. It can be concluded that the new technologies are promising for further investigation and applications.
