摘要
LCA技术是科学确定污水处理工艺方案的一种有效手段。运用LCA技术,以污水处理工艺设施为主线,将城市污水处理厂的全过程生命周期分为3个阶段:施工建设阶段、生产运行阶段和报废拆除阶段,并结合LCA的基本框架对污水处理厂的全过程生命周期进行了分析。该生命周期评价模式不仅考虑了环境因素,而且考虑了技术和经济因素。通过具体实例的分析,对所提评价模式进行论证,评价出两种不同污水处理工艺方案的优劣。
Life Cycle Assessment（LCA） technology is an effective means in determining sewage treatment processes scientifically. This paper uses a sewage treatment process facility as the main line with the application of LCA technology. The Whole Life Cycle of the municipal wastewater treatment plants is divided into three stages：construction stage, operation stage, discarding and removing stage. This paper analyses the whole life cycle of the municipal wastewater treatment plants by the basic framework of LCA. Not only environmental load but also economic and technical factors are contained in the LCA mode. It is demonstrated by the concrete example of two municipal wastewater treatment plants, with evaluating the advantages and disadvantages of the two treatment processes accordingly.
