This paper expounds the background and significance of the national standard of the development on the minimum allowable values of energy efficiency and energy efficiency grades for submersible pushing-flow agitator and rotary aerator in wastewater treatment, and introduces the general principle of the standard, the determination of the minimum allowable values of energy efficiency, the division of the energy efficiency grades for them, as well as the testing and calculation methods. It hopes to eliminate the production of the high energy consumption sewage treatment equipment, and enhance their level of the energy efficiency effectively through development and implementation of the national standard.

Research on the national standard of the minimum allowable values of energy efficiency and energy efficiency grades for key sewage treatment equipment
