摘要
基于对成都市老旧小区、高层电梯住宅等不同居民住宅类型的油烟进行监测,得到不同时段PM2.5和VOCs的排放浓度特征,并采用排放因子法计算得到成都市PM2.5和VOCs的单户年平均排放量。成都市本次PM2.5浓度在0.028~0.745mg/m3,高层住宅单户平均年排放量为0.047 kg/a,老旧小区单户平均年排放量为0.222 kg/a;VOCs平均浓度在0.856~3.695 mg/m3之间,高层住宅单户平均年排放量为0.355 kg/a,老旧小区单户平均年排放量为0.491 kg/a。
Based on the monitoring data of Cooking-Fume of different residential types such as old residential buildings and high-rise residential buildings in Chengdu,the emission concentration characteristics of PM2.5 and VOCs in different time periods are obtained,and the average annual emission levels of PM2.5 and VOCs from a family unit in Chengdu were calculated by emission factor methods.The PM2.5 concentration in Chengdu is between 0.028 and 0.745 mg/m3,the average annual emission of high-rise residential buildings per family is 0.047 kg/a,and that of old residential buildings is 0.222 kg/a;the average VOCs concentration is between 0.856 and 3.695 mg/m3,the average annual emission of high-rise residential buildings per family is 0.355 kg/a,and that of old residential buildings is 0.491 kg/a.
