【Abstract】 To avoid the eutrophication of the water bodies,nitrogen and phosphorus removal must be carried out before 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,characteristics and influencing factors of four types of simultaneous nitrogen and phosphorus removal technologies,including 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 advantages in reducing operating cost and recovering phosphorus resource,and thus becomes a research hotspot in the field of nitrogen and phosphorus removal in wastewater.更多还原
