摘要
挥发性有机化合物(VOCs)与.OH的反应是对流层臭氧形成的重要化学过程,是导致城市光化学烟雾的根本原因。为建立沈阳市固定燃烧源VOCs排放清单,选取了电力热力行业、钢铁行业和秸秆燃烧3个主要排放源进行研究。结果表明:(1)2007年,沈阳市固定燃烧源VOCs排放总量为8 544.539 t,其中排放量最大的是秸秆燃烧,为6 317.115 t;其次是电力热力行业,为2 225.780 t;最小的是钢铁行业,为1.644 t。(2)沈阳市各区县固定燃烧源VOCs排放量由大到小排序依次为新民市、法库县、东陵区、康平县、辽中县、于洪区、苏家屯区、大东区、沈北新区、铁西区、沈河区、皇姑区、和平区;VOCs排放强度由大到小排序依次为大东区、沈河区、铁西区、东陵区、皇姑区、和平区、于洪区、苏家屯区、法库县、康平县、辽中县、沈北新区、新民市。
Volatile organic compounds（VOCs） are the key precursors of photochemical smog.In order to establish the VOCs emission inventory of stationary combustion source in Shenyang,electric power and heat power industry,steel industry and crop straw burning were chosen as the representative stationary combustion source to calculate the VOCs emission.The VOCs emission of electric power,heat power industry and steel industry was analyzed base on the field sampling in typical enterprise,while the VOCs emission from crop straw burning was calculated by method of emission factors.The results showed that,in 2007,crop straw burning emitted the most VOCs of 6 317.115 t,which was followed by the electric power and heat power industry with the VOCs emission was 2 225.780 t,and the steel industry emitted the least VOCs of 1.644 t.Moreover,the districts which had VOCs emission of more than 1 000 t were Xinmin District,Faku District,Dongling District and Kangping District;Dadong District,Shenhe District and Tiexi District were the top three districts for VOCs emission intensity.The VOCs emissions amount and emission intensity of Dongling District were both considerable,but Shenbei New District was in the opposite situation.
