摘　　要：为分析华北地区某化工装置A与企业B对某受体区域污染程度的影响,选用化学质量平衡模型(CMB)定量解析污染来源。首先,利用开路式傅里叶变换红外光谱(OP-FTIR)设备在线监测A与B的污染物排放数据,结合相关性分析建立了二者的成分谱库;在此基础上,根据受体区域污染物在线监测数据,利用CMB完成了污染物来源的定量解析。研究结果表明:受体位置的烷烃及苯系物主要来自A,氨气近乎完全来自B,该解析结果与现场实际及工艺资料相吻合。Source apportionment technology of gas pollution is an important part of air pollution prevention and control.In order to quantitatively analyze the influence of unit A and factory B on the pollution degree of a receptor in North China,chemical mass balance(CMB) was chosen.Firstly,the pollutant emission data of unit A and factory B were monitored online by open-path Fourier transform infrared spectroscopy(OP-FTIR) equipment,and source profile of A and B were established based on the correlation analysis.And then according to the on-line monitoring data of pollutants in the receptor area,the quantitative analysis of the sources of pollutants was completed by CMB.The results showed that the alkanes and benzene were mainly from the unit A and ammonia was almost completely from the factory B,which was consistent with the actual situation of field and process information.
