Analysis of Electricity Consumption and Energy-Saving Measures in Urban Sewage Treatment Plants
Urban sewage treatment plants consume a lot of electricity and energy.Taking a sewage treatment plant in a certain town as an example,this paper analyzes the electricity consumption of power consuming units and proposes energy-saving measures.The sewage treatment process of this sewage treatment plant is municipal sewage → pre-treatment →regulating tank → anaerobic-anoxic-oxic(A2O)reaction tank → secondary sedimentation tank → flocculation reaction sedimentation → filter tank → disinfection tank → effluent.The results indicate that the main power consuming equipment of the sewage treatment plant is the blower and water pump.Therefore,it is necessary to focus on the blower,lifting pump,and reflux pump,and take corresponding energy-saving measures to achieve good energy-saving effects.
