Study on Comprehensive Assessment of Wastewater Treatment Plants in Jiulong River Catchment Based on the Method of Life Cycle Assessment

Abstract

随着我国城市化水平的不断提高,今后我国的大部分人口将生活在中小城镇。目前,中小城镇的环境保护问题越来越引起重视,污水处理的重心正在由大城市转向中小城镇,中小型污水处理厂日益增多。利用生命周期评价方法对中小城镇污水处理厂污水处理工艺进行全面综合评价,可以通过一个完整的污水处理生命周期对不同处理工艺所带来的环境影响作出定性定量分析,为未来污水处理厂的建设提供参考信息。 作为一种有效的环境管理工具,生命周期评价已经得到世界各国的广泛采用,它作为一种评价产品、工艺或服务从“摇篮”到“坟墓”这一过程的环境影响的工具,它从原材料采集到加工制造、产品使用及用后处理进行全过程跟踪,并采用定性与定量相结合的方...As the urbanization in China, most of population will be living in small and medium-sized towns in the future. At present, the environmental issues of small and medium-sized towns are brought to the forefront more and more, and the main part of wastewatet treatment is transferring from big cities to small and medium towns, consequently, the small and medium-sized wastewater treatment plants are pr...学位:理学硕士院系专业:海洋与环境学院环境科学与工程系_环境科学学号:2122005130225
