摘　　要：综述了有机废水分置式生物脱硫和生物脱氮的基本原理及常见工艺,在此基础上,介绍了2种新型同步脱硫脱氮技术———基于硫化物型反硝化(以硫化物为电子供体的反硝化)和硫酸盐型厌氧氨氧化(以硫酸盐为电子受体的厌氧氨氧化)的同步脱硫脱氮法,分别从反应机理、控制条件和功能微生物等方面对其进行了阐述。新型同步脱硫脱氮技术的开发将有助于富含硫酸盐和氨氮有机废水的高效、节能处理和实现资源回收。According to the summary of biotechnology principles and common processes for the separated desulfurization and denitrogenation from organic wastewater,two novel bioteehnologies for removing sulfur and nitrogen simultaneously,which are based on sulfide-dependent denitrification （denitrification with sulfide as electron donor） and sulfate-dependent ANAMMOX （anaerobic ammonium oxidation with sulfate as electron acceptor）,are introduced. The reaction mechanism,operating conditions and functional organism for the new techniques are described. It is considered that the novel process of simultaneous desulfurization and denitrogenation would be of great benefit to the treatment of organic wastewater containing high sulfate and ammonia-nitrogen in efficiency- improving, energy-saving and resource recovery.
