摘要
在国家持续推动双碳目标落地和乡村振兴的大背景下,针对河北省有机废料低碳、高效资源化利用问题,构建了农业有机废料沼气化综合评价模型,开展了沼气量潜力核算、收集运输碳排放、沼气工程项目建设远景适宜性等方面的细分量化评估。结果表明:2021年河北省农业有机废料理论沼气产量巨大,约为2.64×10^(10)m^(3),可折算标准煤1887.69×10^(4) t或天然气155.37×10^(8) m^(3),但分布趋势总体不均,地市差异较大,邯郸、保定、石家庄处于第一梯队,秦皇岛、廊坊、承德沼气潜力较差;理论沼气产量替代标准煤使用可减少CO_(2)排放量4.10×10^(7) t,同时产生的沼液沼渣用于农用可替代化肥43.18×10^(5) t;结合经济指标、农牧业发展指标分析发现衡水、石家庄、邯郸三地的农业有机废料沼气化工程项目建设远期综合适宜性最佳。本项研究可为河北省农业有机废料处理处置、农村能源结构优化配置、农业绿色低碳发展转型、农村地区碳排放核算等工作提供参考。
Against the backdrop of the national continuous promotion of the dual carbon goals and rural revitalization,a comprehensive evaluation model for the low-carbon and efficient utilization of organic waste in Hebei Province was constructed.Quantitative assessments were conducted in areas such as biogas potential calculation,carbon emissions from collection and transportation,and suitability of biogas project construction in the future.The results indicated that in 2021,there was a huge theoretical biogas production potential from agricultural organic waste in Hebei Province,estimated at approximately 2.64×10^(10)m^(3),equivalent to 18.87million tons of standard coal or 15.537 billion cubic meters of natural gas.However,the distribution trend was uneven,with significant differences among cities.Handan,Baoding,and Shijiazhuang were in the first tier,while Qinhuangdao,Langfang,and Chengde had lower biogas potential.The substitution of theoretical biogas production for natural Standard coal usage could reduce CO_(2) emissions by 4.10×10^(7) tons.Additionally,the biogas slurry and residue generated could replace 4.318 million tons of chemical fertilizers for agricultural use.The analysis of economic indicators and agricultural development indicators revealed that Hengshui,Shijiazhuang,and Handan had the best comprehensive suitability for the long-term construction of agricultural organic waste biogas projects.This study will provide references for the disposal and utilization of agricultural organic waste,optimization of rural energy structure,transformation of agricultural green and low-carbon development,and carbon emission accounting in rural areas of Hebei Province.
