通过2009—2014年浙江省农村能源的使用情况,计算各类能源的SO_2,NO_X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SO_2、NO_X、TSP的排放量和贡献度来看,煤炭贡献了94.3%的SO_2、86.6%的NO_X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NO_X和SO_2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SO_2、NO_X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、NO_X排放量的有效措施。
Based on the use of rural energy in Zhejiang Province from 2009 to 2014, the pollutant emissions of SO 2, NO_X and TSP (Total suspended particulate) of various energy sources and their contributions were calculated. The research shows that the energy structure of rural areas in Zhejiang Province is at a stage where traditional energy sources dominate, and the popularization and utilization of new energy sources still need to be developed. From the emission and contribution of SO 2, NO_X and TSP, coal contributes 94.3% of SO 2 , 86.6% of NO_X and 39.8% of TSP emissions. The fuelwood contributes mainly to TSP emissions by 25.7% and straw contributes to TSP emissions by 34.5%, but has a very low contribution to NO_X and SO_2 of 8.9% And 2.4%. Optimize the energy structure, the use of clean coal instead of clean energy, more complete desulfurization of coal is an effective measure to reduce SO 2, NO_X emissions; change the use of straw, through advanced transformation technology, the straw into high-grade fuel Is to reduce TSP, NO_X emissions effective measures.
