BOD/COD选取对污水处理厂甲烷排放量估算的影响——以杭州市为例

摘要

简述了采用不同BOD/COD模式估算污水处理厂污水处理中甲烷的排放量,对于污水处理厂甲烷排放的研究以及总的温室气体排放研究、全球气候变化的研究具有重要的意义.运用IPCC估算模式,分别采用BOD/COD的指南推荐值和实测值进行了2011-2014年杭州市污水处理厂污水处理中甲烷排放量的估算,分析了排放状况,对比了排放结果,为污水处理厂甲烷排放量估算中排放因子的采用提供了参考依据.%Using different BOD/COD models to do methane emission calculation in wastewater treatment plant is significant to the research on methane emission in wastewater treatment plant,the estimation of total greenhouse gas emissions and the future climate change.Based on the IPCC estimation model,we used the recommended values and measured values of BOD/COD to estimate the methane emission from wastewater treatment of Hangzhou Sewage Treatment Plant in 2011-2014,analyzed the emission status,compared the emission result,and provided a reference for the selection of emission factors in the estimation of methane emission from wastewater treatment plants.
