The invention discloses a complex microbial inoculant for deep nitrogen and phosphorus removal of sewage, the complex microbial inoculant comprises ammonia oxidizing bacteria, ammonia oxidizing archaea, whole-course nitrifying bacteria, anaerobic ammonia oxidizing bacteria and phosphorus-accumulating bacteria, different strains have different metabolic pathways and biological activities and can complement each other, the metabolism and biosynthesis effects of the strains are optimized, and the nitrogen and phosphorus removal efficiency is improved. The reaction rate is increased, and the nitrogen and phosphorus removal rate is improved. The invention further discloses a sewage treatment system, the system is composed of nine treatment units and a precipitation device, a part of the treatment units are provided with stirring devices, aeration devices and reflux devices at the same time, flexible switching of the anaerobic unit, the anoxic unit and the aerobic unit can be achieved, and flexible switching of mul
