城市污水厂污泥处理处置过程中碳排放核算边界浅析

Brief Analysis of Carbon Emission Accounting Boundaries in Process of Sludge Treatment and Disposal of Municipal Sewage Plant

污水厂污泥处理处置过程中会产生大量的温室气体,开展不同污泥处理处置工艺碳排放的核算方法研究具有重要的意义。在碳排放核算过程中,为了实现核算的准确性,避免重复计算和漏算,需要考虑碳排放的各核算边界,而核算边界的确定一般需要参考各工艺流程以及处理设施等因素。文中对污泥处理处置工艺的核算边界,即碳源和碳汇进行了分析,并以目前国内外主要的3种处理处置工艺为例,通过对核算边界的分析,为之后碳排放核算方法的建立提供了理论依据。

A large amount of greenhouse gases are produced during the treatment and disposal of sewage sludge.Therefore,it is of great significance to study the accounting methods of carbon emissions from different sludge treatment and disposal processes.In the process of carbon emissions accounting,in order to achieve the accuracy of accounting and avoid repeated calculation and omission,it is necessary to consider the accounting boundaries of carbon emissions,while the confirmation of accounting boundaries generally needs to refer to the facts such as each technological process and treatment facilities.In this paper,it analyzed on the accounting boundaries of sludge treatment and disposal,which refers to the carbon source and carbon sink.Three main treatment and disposal processes at home and abroad were taken as examples to analyze accounting boundaries,to provide a theoretical basis for establishment of carbon emission accounting method.
