城市污泥土地利用碳排放的研究进展

Research Progress in Carbon Emission from Sewage Sludge Land Application

污泥土地利用是资源化利用的主要途径,介绍了城市污泥土地利用直接排放和碳补偿的温室气体核算方法的研究进展,结合我国污泥土地利用实际情况,分析了应用IPCC清单法核算污泥土地利用碳排放过程中存在的具体问题,并提出了相应建议。

Sewage sludge land application is a primary approach to achieve sludge resource reuse. The methods for calculating greenhouse gas （GHG） emissions and carbon offsets from sludge land appli- cation were presented. Combined with the actual sludge land application in China, problems in calcula- tion of carbon emissions from land application by Intergovernmental Panel on Climate Change （IPCC guidelines were analyzed, and some advices are proposed.
