层次分析法在污水处理能耗评价中的应用

Application of the Analytical Hierarchy Process in the Evaluation System of Energy Consumption for Wastewater Treatment Plants

运用层次分析法,建立了一个污水处理厂的能耗评价体系,并对在我国应用较多的氧化沟工艺和A^2/O工艺的两座污水处理厂的能耗状况进行了分析。将能耗调查结果与能耗评价体系的计算结果进行了对比,证明了该评价体系的可行性。对将来污水厂的设计和运行管理具有一定的指导作用。

To construct a wastewater treatment plant is the most significant way to control water pollution. Due to high construction and operation cost, the process of wastewater treatment was much restricted. In order to evaluate the energy consumption in different wastewater treatment plants, a comprehensive evaluation system of energy consumption is established by adopting the analytic hierarchy process and the chief factors of energy consumption in the wastewater treat- ment plant. The conclusion shows that this evaluation system can verify the energy consumption in the wastewater treat- ment plant. This can provide references for engineering design and operation of future wastewater treatment plants.
