- Abstract:
- Based on energy consumption data of 1 291 wastewater treatment plants (WWTPs) from the China Urban Drainage Statistical Yearbook (2016), energy consumption statistical analysis was conducted with the normalized method, revealing the interaction between energy consumption and various factors including scale, loading rate, treatment process, effluent standard and influent COD of the WWTPs. The interactive effects of two factors were investigated. The total average unit energy consumption was (0.317±0.229) kW·h/m3 in China. There was a significant relationship between the five selected factors and energy consumption, and there was a certain synergistic effect. A matrix table of China WWTP energy benchmarking was constructed based on scale, influent quality and loading rate. Finally, this research proposed to formulate a phased development plan for WWTP energy management strategies. In the short term, the median value (top 50%) of statics should be set as the benchmarking, and the value of top 25% or 10% should be considered as benchmarking in the long-term plan with the gradual stability of operation and the rise of operation level.
