Operational energy performance assessment system of municipal wastewater treatment plants

摘要

Based on the statistical analysis of operational energy consumption and its influential factorsnfrom data of 599 Chinese WWTPs in 2006, it is noticed that the most influential factors includentreatment technology adopted, treated sewage amount, removed pollutants amount, etc.nUsing the conclusion above, this paper sets up an integrated system of operational energynperformance assessment for municipal wastewater treatment plants. Combining with result fromnon-spot research and model simulation, the calculating method of benchmark value and score ofn7 energy efficiency indicators grouped into 3 levels is stated. Applying the assessment system tonthree plants, its applicability and objectivity are proved and suggestions to improve energynperformance are provided.
