污水处理厂能耗评估与优化现状

Present situation of the energy consumption evaluation and optimization in wastewater treatment plants

污水处理是能耗密集型技术,为了能对污水处理过程进行合理的能耗评估和降低污水处理能耗,各国研究学者在此方面都做了大量的研究工作。文章从污水处理厂能耗现状入手,对能耗评估指标、能耗基准线的划定方法、能源效率提高办法、能源监管等几个方面进行了综述。通过分析发现,污水处理厂的能源效率通过评估和管理是可以大幅度提升的,将来还有很多值得研究的空间。

Wastewater treatment is an energy intensive type technology.In order to make reasonable evaluation on the energy consumption in wastewater treatment processes and reduce the energy consumption,researchers from various countries have made great efforts in this field.This paper firstly starts with the present situation of energy consumption in wastewater treatment plants.Then,the aspects of energy consumption evaluation indicators,delimitation of energy consumption baseline,energy efficiency improvement and energy regulation,etc.are summarized.It is found through analysis that the energy efficiency in wastewater treatment processes could be improved greatly by properly using energy evaluation and management,and there are still a lot of spaces worth studying.
