摘要
农作物秸秆燃烧后会向空气中释放大量颗粒物,不仅对大气环境及生态系统产生影响,也对人们健康造成危害。因此文中以秸秆燃烧后颗粒物排放水平作为研究方向,探究秸秆燃烧情况对PM2.5排放因子的影响水平。首先,针对河南主要两种农作物玉米秸秆和小麦秸秆进行燃烧模拟实验,获取秸秆燃烧后颗粒物排放水平,从而得到颗粒物中PM2.5的排放因子含量及化学组成;然后,利用两种农作物,通过改变燃烧条件、秸秆水分含量等条件获取燃烧后的排放因子数据,并分析不同条件对PM2.5排放因子比例的影响;最后,利用排放因子法根据不同农作物燃烧时产生的排放因子估算该区域PM2.5排放总量水平,并与近5年秸秆燃烧PM2.5排放总量提供数据进行对比。实验证明,通过该实验可较好地反映秸秆燃烧对区域环境产生的影响。
After the straw burning,it will release a large number of particles into the air,which not onlyaffects the atmospheric environment and ecosystem,but also harms people's health level.Therefore,inthis paper,the level of emissions of particulate matter after straw combustion as the research direction,toexplore the impact of straw combustion on PM2.5emission factors.First of all,according to the Henantwo main crops of corn and wheat straw burning simulation experiment,obtained after combustionparticulate emission levels,emission factors obtained from the composition content and chemical PM2.5particles;then,using two kinds of crops,to obtain emission factor data after combustion conditions bychanging the combustion conditions,the moisture content of straw etc.,and analyze the influence ofdifferent conditions on PM2.5emission factor ratio;finally,using the emission factor method according tothe emission factors of different crops produced during the combustion of the PM2.5emission levelestimation area,and nearly6years of straw combustion and PM2.5emissions data comparison.Theexperiment shows that the effect of straw combustion on the regional environment can be well reflectedby the experiment.
