摘要:以造纸污泥为研究对象,应用生命周期评价方法对造纸污泥干燥焚烧的生命周期进行清单分析,以获得造纸污泥干燥焚烧处理方式的能耗及其对环境的影响,实现对全球变暖(GW)、大气酸化(AC)、水体富营养化(NE)以及烟尘和灰尘(SA)等环境影响的定量化,以获得污泥处理对环境影响的程度和趋势。

Abstract:Taking the paper sludge as the research object, using life cycle assessment to analyze the inventory of paper sludge drying and combustion, in order to obtain the energy consumption and its impact on the environment, to quantify its environmental impact such as global warming, atmospheric acidification, eutrophication of water body, dust and ash, finally to understand the extent and trend of sludge treatment plants impact on the environment.
