对成都8 家社会餐饮企业排放的PM2.5和VOCs监测分析,结果表明,餐饮企业排放的PM2.5平均质量浓度为(1.32±0.84)mg/m3,VOCs 平均质量浓度为(0.37±0.45)mg/m3,VOCs的主要成分是48%的苯系物,22%的烷烯烃以及20%的酮类。根据餐饮企业的活动水平和实际监测结果,以就餐人数为基准得到的PM2.5和VOCs的排放因子分别为0.80 g/(人·次)和0.11 g/(人·次),以用油量为基准得到的PM2.5和VOCs的排放因子分别为8.5 g/kg和1.4 g/kg。 |

This paper conducted the measurements of cooking emission from 8 restaurants in Chengdu.The mass concentration of PM2.5 and chemical compositions of VOCs were analyzed based on the filter and Canister samples.The mass concentration of PM2.5 is (1.32±0.84)mg/m3,while the concentration of VOCs is (0.37±0.45)mg/m3.The main components of VOCs are BTEX (48%),alkanes olefins (22%) and ketones (20%).The PM2.5 and VOCs emission factors on the basis of person in commercial restaurant are 0.80 g/(person·time)and 0.11 g/(person·time),while PM2.5 and VOCs emission factors on the basis of oil are 8.5 g/kg and 1.4 g/kg. |
