摘要
基于2018年现场实测数据,以山东省为典型案例研究,综合考虑现有生产技术、生产规模、炉型工艺及年垃圾焚烧量等因素,自下而上构建山东省垃圾焚烧发电厂PCDD/Fs排放清单,并采用空气质量模型CALPUFF定量评估现状及不同情景下垃圾焚烧PCDD/Fs排放及其环境影响.结果表明:PCDD/Fs排放因子范围为24.68~290.90ng TEQ/t,平均值为75.11ng TEQ/t,年排放量为1.07g TEQ,排放因子、排放量均低于已有研究.从炉型维度分析:炉排炉排放因子低于循环流化床,表明其PCDD/Fs排放控制水平较好;从空间分布维度分析:潍坊市,济宁市和淄博市的垃圾焚烧量最大,其排放量与大气模拟浓度也相对较高;从情景对比维度分析:标准加严、垃圾焚烧率提高的未来情景更符合山东省垃圾焚烧电厂的未来发展规划要求,同时也可达到降低PCDD/Fs排放及其环境影响的目标;相比2018年基准情景,该情景下的年排放量以及年均浓度贡献将分别下降22.73%,24.19%.
Based on the field measured data in 2018,this study takes Shandong Province as a typical case study and comprehensively considers the production technology,production capacity,incinerator type and annual MSW incineration amount,to establish PCDD/Fs emission inventory of municipal solid waste(MSW)incineration power plants in Shandong Province using the bottom-up approach and introduce CALPUFF model to quantitatively evaluate environmental impacts caused by PCDD/Fs emissions under current and different scenarios.The results show that the range of PCDD/Fs emission factors was 24.68~290.90ng TEQ/t,with an average value of 75.11ng TEQ/t.The total emission was 1.07g TEQ in 2018.The estimated emission factors and total emissions were lower than existing studies.In terms of incinerator type,the emission factor of grate firing incinerators was lower than that of fluidized bed incinerators,indicating that it has a good control effect on PCDD/Fs emissions.In terms of spatial distribution,the largest MSW incineration amount was mainly concentrated in Weifang,Jining and Zibo city,and total emissions and atmospheric simulated concentrations were also relatively high.In terms of scenario comparison,the future scenario with stricter standards and improved MSW incineration rate was more in line with the requirements of the future development planning of the MSW incineration industry in Shandong Province,and can also achieve the goal of reducing the PCDD/Fs emissions and environmental impacts.Compared with the baseline scenario,the average annual concentration contribution in this scenario will be reduced by 22.73%and 24.19%,respectively.
