摘　　要：相较于传统废水生物脱氮技术,微藻技术可将含氮污染物同化,并且具有产生蛋白和脂类等特点,能够被人类加工利用。单独培养微藻存在生长缓慢不稳定、抗冲击能力弱和脱氮能力差等弊端,而微藻共培养技术可通过诱导真菌、细菌等外源微生物进行种间营养代谢交换、促进稳定生长和提高氮去除和回收效率,具有较好的可利用价值。指出了物理化学脱氮技术的局限性,并结合国内外研究阐述了微藻脱氮机理,总结分析了微藻—真菌、微藻—细菌和微藻间共培养特征及其应用前景,并提出微藻在未来处理城镇污水等方向具有深远的推广意义,而在实验室阶段更应对微藻共培养技术中关于光利用、种间互作机理等方面进行深入解析。Compared with the traditional wastewater biological denitrification technology,microalgae technology can assimilate nitro-gen-containing pollutants and has the characteristics of producing proteins and lipids,which can be processed and utilized by human beings.Indi-vidual culture of microalgae has the disadvantages of slow and unstable growth,weak shock resistance and poor nitrogen removal,while microalgae co-culture technology can be utilized by inducing exogenous microorganisms,such as fungi and bacteria,to carry out interspecies nutrient metabo-lism exchanges,to promote stable growth,and to improve nitrogen removal and recycling efficiencies,which has a better utilization value.pointing out the limitations of physicochemical denitrification technology,describes the mechanism of microalgae denitrification in combination with domes-tic and international research,summarizes and analyzes the characteristics of microalgae-fungi,microalgae-bacteria and microalgae co-cultivation and its application prospects,and proposes that microalgae have far-reaching significance in the future treatment of urban sewage and other direc-tions,and that microalgae co-cultivation should be further analyzed in the laboratory stage with respect to the utilization of light and the interspecies interplay mechanism.In the laboratory stage,the light utilization and interspecies interaction mechanism of microalgae co-culture technology should be analyzed.
