摘　　要：对南北两地的5台生活垃圾焚烧炉尾部烟气、2个生活垃圾填埋场的填埋堆体覆膜区域和2个污水处理厂的开放式工艺池分别进行了长达1 a的温室气体CO_(2)、CH_(4)、N_(2)O监测。焚烧炉尾部烟气中吨垃圾CO_(2)排放强度年均值为0.653~0.797 t,运行工况稳定情况下其核算值与监测值的相对误差最低可达1.86%。填埋堆体覆膜区域的温室气体排放通量随季节波动性很大,南方地域夏天排放最高值CO_(2)可达11.13 g/(m^(2)·h)、CH_(4)可达0.98 g/(m^(2)·h)、N_(2)O可达3.519 mg/(m^(2)·h)。污水处理工艺池CO_(2)和N_(2)O排放以曝气池为主,其中CO_(2)受季节变化影响不大,N_(2)O的全年波动大。北方污水厂CH_(4)的排放通量有明显季节差异,以缺氧池、选择池、厌氧池在夏季的数值最高,最高达到1.60 g/(m^(2)·h)。南方污水处理工艺池中CH_(4)排放能力仍然以3个曝气池为主,全年波动大且无明显季节差异,最高约达到0.40 g/(m^(2)·h)。Greenhouse gases CO_(2),CH_(4)and N_(2)O were monitored for up to one year in the tail gas of five municipal solid waste incinerators,the areas covered with films of two domestic waste landfills and open processing pools of two wastewater disposals,respectively.The average annual CO_(2)emission capacity of tons of waste in the flue gas of incinerator tail was in the range of 0.653 to 0.797 t.The relative error between the calculated value and the monitored value was as low as 1.86%under stable operating conditions.The greenhouse gas emission flux in the covered area of landfill fluctuated greatly with the seasons.The maximum emission levels of CO_(2)could reach 11.13 g/(m^(2)·h),CH_(4)could reach 0.98 g/(m^(2)·h),and N_(2)O could reach 3.519 mg/(m^(2)·h)in the southern region in summer.The CO_(2)and N_(2)O emissions from the wastewater treatment process tank were mainly in the aeration tank,in which CO_(2)was not affected by the seasonal change,and N_(2)O fluctuated greatly throughout the year.As to CH_(4),the discharge fluxes in the north sewage plant had obvious seasonal differences,and the values of anoxic pool,selective pool and anaerobic pool were the highest in summer.The highest data was 1.60 g/(m^(2)·h).The CH_(4)discharge capacity of the sewage treatment process tank in southern China was still dominated by three aeration tanks,which fluctuated greatly throughout the year and had no obvious seasonal difference,and could reach about 0.40 g/(m^(2)·h).
