- Abstract:
- This paper analyzed the energy consumption data of a wastewater treatment plant in Taihu Lake basin in recent ten years by mathematical analysis method, and investigated the effects and influence degree of water quantity, pollutants and water temperature on energy consumption fluctuation, respectively. In the past ten years, the energy consumption per volume of wastewater in the plant fluctuated significantly in the range of 0.15-0.45 kW·h/m3. The analysis of influencing factors indicated that the energy consumption per volume of wastewater was negatively correlated with the water quantity as a power function. For every 10% increase in water quantity, the energy consumption per volume of wastewater was reduced by approximately 12%, showing that there was a scale effect. Among various pollutants, nitrogen?containing pollutants had the most significant influence on energy consumption fluctuation. The energy consumption per volume of wastewater was negatively correlated with water temperature in the period of large temperature variation. A comprehensive comparison showed that water quantity had the greatest influence on fluctuation of energy consumption, which could provide a reference for evaluating the stable operation of wastewater treatment plants.
