Abstract:Aiming at the contradiction between the improvement of the effluent standard of sewage treatment plants in small towns and energy saving and consumption reduction, a comprehensive energy saving plan covering energy saving and consumption reduction methods such as comprehensive evaluation of sewage treatment plant efficiency, management energy saving, control energy saving, and equipment energy saving has been established. Taking a sewage treatment plant in Kunshan as an example, it has carried out energy-saving and consumption-reduction work in sequence from facility streamlining, equipment renewal, and control optimization. Under the condition of stable sewage discharge and up to standard, the unit power consumption is reduced by 32.5%, which is an energy-saving reduction for small-scale urban sewage treatment plants. Consumption provides examples that can be used for reference.
