基于天津市非道路移动源污染管控需求,根据调研收集到的2015年非道路移动源活动水平数据,采用环保部《非道路移动污染源排放清单编制技术指南(试行)》推荐的核算方法,建立较为完整的天津市非道路移动源排放清单,分析污染物的时空分布.2015年,天津市非道路移动源排放CO 6.15×10~3t、HC 2.45×10~3t、NO_x2.90×10~4t、PM 1.45×10~3t、SO_21.37×10~4t.船舶污染物排放占比最高,为所有非道路移动源污染物排放总量的73.66%,主要分布于天津港区;其次是非道路移动机械,占21.66%,主要分布于市郊种植业和养殖业区县、城市建设和人群活动较为密集的城区;民航飞机和铁路机车占比较小,分别为3.55%和1.13%,主要分布于机场和铁路沿线.总体上,非道路移动源从3月开始排放量逐渐升高,而年底和年初(冬季)排放量相对较低.
Based on the non-road mobile sources pollution control requirements in Tianjin, based on the 2015 non-road mobile source activity data collected from the survey, the MEP’s recommended method for calculating the non-road mobile sources emission inventories (for Trial Implementation) A complete inventory of non-road mobile sources in Tianjin and analysis of space-time distribution of pollutants In 2015, non-road mobile sources in Tianjin emitted CO 6.15 × 10-3 t, HC 2.45 × 10-3 t, NO x 2.90 × 10 -4 t, PM 1.45 × 10 ~ 3t, SO_21.37 × 10 ~ 4t.The proportion of pollutant emissions from ships is the highest, accounting for 73.66% of all non-road mobile pollutants, mainly distributed in Tianjin port area, followed by non-road mobile machinery , Accounting for 21.66%, mainly distributed in suburban farming and aquaculture districts, urban construction and crowded urban areas; civil aircraft and railway locomotives accounted for a relatively small proportion of 3.55% and 1.13% respectively, mainly distributed in airports and railways In general, emissions from off-road sources have been rising from March onwards, with relatively low end-of-year and early-winter (winter) emissions.
