化学需氧量在线自动监测仪强检工作问题及对策

Discussion on the problems and countermeasures of the strong inspection of chemical oxygen demand online automatic monitor

对化学需氧量在线自动监测仪计量工作中存在的问题进行分析,提出相应的解决对策.从测量点的选择、仪器漂移及稳定性的考核,政府、环保单位及设备商对计量工作的执行情况等进行分析,提出通过加强政府、企业对于《计量法》及强检计量器具检定工作的宣贯,对于仪器选择更合理的测量点位,制定更合理的稳定性评价标准等方法,提高对仪器性能的有效评定,解决目前化学需氧量在线自动监测仪计量工作存在的常见问题.

The problems existing in the measurement of chemical oxygen demand online automatic monitor were analyzed,and the corresponding solutions were proposed. From the selection of measurement points,the assessment of instrument drift and stability,the government,environmental protection units and equipment vendors, the implementation of the analysis,etc.,it can be achieved by strengthening the government and enterprises to the Metrology Rule and the inspection of the measurement equipment for strong inspection,the selection of more reasonable measurement points for the instrument,the development of more reasonable stability evaluation criteria,etc. The method improves the effective evaluation of the performance of the instrument and solves the common problems existing in the current measurement of the chemical oxygen demand online automatic monitor.
