摘　　要：为避免造成水体富营养化,污水排放前必须进行脱氮除磷处理。与传统技术相比,新型同步脱氮除磷技术具有能耗低、占地小等特点,是污水处理领域中新的工程应用方向。介绍了生物法、物理化学法、生物电化学法和生物诱导矿化法4类同步脱氮除磷技术的原理、特点及影响因素。其中,生物诱导矿化法作为新型的生物-矿物结晶耦合处理技术,在降低运行成本和磷资源回收方面具有较大的优势,成为污水脱氮除磷领域的研究热点。To avoid the eutrophication of the water bodies,nitrogen and phosphorus removal must be carried out be-fore the sewage is discharged.Compared with the traditional removal technologies,the new simultaneous nitrogen and phosphorus removal technologies have the characteristics of low energy consumption and small footprint,leading to a new engineering application direction in the field of sewage treatment.This peper introduces the principles,chara-cteristics and influencing factors of four types of simultaneous nitrogen and phosphorus removal technologies,inclu-ding biological method,physical chemical method,bioelectrochemical method and biological induced mineralization method.As a new bio-mineral crystal coupling treatment technology,bio-induced mineralization method has great adv-antages in reducing operating cost and recovering phosphorus resource,and thus becomes a research hotspot in the field of nitrogen and phosphorus removal in wastewater.
