人工湿地处理系统的生命周期成本评估

Evaluation on Life Cycle Cost of Constructed Wetland Treatment System

通过对人工湿地处理系统进行生命周期成本评估,可以从经济角度分析出人工湿地比传统水处理技术具有更好的经济效益,从而为项目决策提供依据。从建设阶段和运营阶段两方面系统论述了人工湿地处理系统生命周期成本评估时需要考虑的主要因素,以及核算不同时期运营成本的净现值法,介绍了国外关于人工湿地处理系统的生命周期成本评估方法,对建立完善的人工湿地及其他水处理系统的生命周期成本评估方法具有一定的借鉴意义。

The life cycle cost evaluation shows that the constructed wetland treatment system has more economic benefits than conventional wastewater treatment system. The achieved results can provide a basis for decision-making department, The key factors for consideration in the life cycle cost evaluation of the constructed wetland treatment system were systematically illustrated in respects of the construction phase and operation phase, The net present value method for the calculation of the operation cost in different stages was also illustrated. The foreign methods for the life cycle cost evaluation of the constructed wetland treatment system were introduced, All of these may provide a reference to establish a flawless method for life cycle cost evaluation of the constructed wetland treatment system and other wastewater treatment system.
