中文摘要:
      对南京市某典型企业固定污染源非甲烷总烃在线监测系统开展比对监测,将在线监测结果和便携式仪器监测、手工监测结果作比对分析。结果表明,在线监测系统线性误差与量程漂移可以满足现阶段管理要求,实际样品比对过程中采用不同的采样分析仪器,监测结果差距较大,便携式分析仪结果相对误差较小(为3.72%),手工监测结果相对误差较大(为48.3%)。建议加强污染源废气手工监测的质控管理,强化在线监测设备的运维管理,推进污染源非甲烷总烃CEMS合理有序发展。
英文摘要:
      An online system for monitoring NMHC from stationary source of a typical enterprise in Nanjing was compared with portable instrument monitoring and manual monitoring. The results showed that the linear error and the span drift of the on line monitoring system could meet the current requirements of management. For actual sample monitoring, different sampling and analysis instruments led to different results. The relative error of portable analyzer was small (3.72%), the relative error of manual monitoring was large (48.3%). It was proposed to strengthen the quality control management of manual monitoring in stationary source emission, reinforce the operation and maintenance management of online monitoring equipments, and promote the rational and orderly development of CEMS for NMHC monitoring.
