浙江省农村能源结构及主要污染物排放量估算
Rural Energy Structure and Emission Estimation of Main Pollutant in Zhejiang Province

摘要: 通过2009—2014年浙江省农村能源的使用情况,计算各类能源的SO2,NOX及TSP(Total suspended particulate)污染物排放量及其贡献度。研究表明:浙江省农村能源结构处于传统能源占主导地位的阶段,对于新型能源的普及与利用仍有待发展;从SO2、NOX、TSP的排放量和贡献度来看,煤炭贡献了94.3%的SO2、86.6%的NOX以及39.8%的TSP排放量,柴薪主要对TSP排放量贡献了25.7%,秸秆对TSP排放量贡献率为34.5%,但对NOX和SO2贡献率很低,分别为8.9%和2.4%。优化能源结构,使用替代煤的清洁能源,对煤炭进行较完全的脱硫处理,是降低SO2、NOX排放量的有效措施;改变秸秆的利用方式,通过先进的转化技术,将秸秆转化为高品位燃料是降低TSP、NOX排放量的有效措施。Abstract: Based on energy consuming data of rural area in Zhejiang province in 2009—2014,the amount of main pollutant including SO2,NOX and TSP were calculated.Results showed that rural energy structure in Zhejiang province remained as a traditional model.From the view of pollutant emission and contribution,coals contributed 94.3% for SO2 ,86.6% for NOX and 39.8% for TSP.The contribution of SO2,NOX and TSP from straws were 8.9%,2.4% and 34.5% respectively.Optimizing energy structure and using clear energy substituting for coals were effective ways to decrease emission of SO2 and NOX.Transforming the straws to high grade biofuels was effective way to decrease emission of TSP and NOX.
