摘要:
应用开放式傅里叶变换红外光谱分析仪(OP-FTIR)对华东地区某化工区周边空气特征污染进行了180 d连续在线监测,建立了污染特征分析、预警评估和污染溯源等体系化监测应用方法,匹配形成了近10项日常数据监控指标的质保质控体系和基于最小二乘法人机结合的谱图解析和数据生成体系,数据误差控制在20%以内。结果表明,通过180 d外场稳定监测,实现了超过40种区域特征污染因子库的建立和实时监控,掌握了乙烯和甲醇等10余种特征污染物的排放规律和主要来源。

Abstract:
180 days Continuous online monitoring of air pollution around a chemical zone in East China was conducted using an open path Fourier transform infrared spectrometer (OP-FTIR). Based on the monitoring, a systematic monitoring application method for pollution characteristics analysis, early warning assessment and pollution traceability was established. Nearly 10 quality assurance and quality control systems for daily data monitoring indicators and spectrum analysis and data generation systems based on least squares man machine integration were matched, which ensure data errors within 20%. Through the long term stable monitoring of the external field for 180 days, the establishment and real time monitoring of more than 40 regional characteristic pollution factor Libraies were realized. In this study, we have mastered the emission patterns and main sources of more than 10 characteristic pollutants such as ethylene and methanol.
