工业废水处理碳排放模型的构建与核算研究

Construction and Calculation of Carbon Emission Model for Industrial Wastewater Treatment

本研究通过生命周期评价的相关理论,以工业废水处理过程中产生的主要温室气体CH_4、N_(2)O、CO_(2)为研究对象,构建了包括废水处理、污泥处理和污泥处置过程的碳排放核算模型,并进行了模型核算研究。研究结果表明,温室气体排放量最大的环节为废水处理环节,其中电力消耗产生的间接碳排放量占该环节碳排放量的90%以上,其次为污泥处置环节,污泥处理环节占比最小。本研究可以为相关行业工业废水处理的碳排放核算提供参考。

Based on the relevant theories of life cycle assessment,this study takes the main greenhouse gases CH4,N_(2)O and CO_(2) produced in the process of industrial wastewater treatment as the research object,and establishes the carbon emission accounting model including wastewater treatment,sludge treatment and sludge disposal.The model calculation is also studied.The study shows that the largest greenhouse gas emission link is the wastewater treatment link,and the indirect carbon emissions caused by electricity consumption account for more than 90%of the carbon emissions in this link.The second is the sludge disposal link,and the sludge treatment link accounts for the smallest proportion.The model can provide reference for carbon emission accounting of industrial wastewater treatment in related industries.
