污泥浓度(MLSS)在线分析仪示值误差的不确定度评定

Uncertainty Evaluation of Indication Error of MLSS Online Analyzer

以HACH生产的sc200污泥浓度(MLSS)在线分析仪为例,对影响其测量结果不确定度的各个分量进行分析,由于目前没有对应的检定规程和校准规范,也没有适用的国家标准物质,因此,采用过滤称重法对仪器的示值误差进行不确定度评定。以期为企业污水的排放监测和工艺控制提供计量数据支撑。

This paper takes the SC200 analyzer on-Line of sludge concentration(MLSS)of HACH as an example,All of affecting the measurement result of each component is analyzed.because there is no corresponding verification regulations and calibration specifications at present,also does not have the applicable national standard substances,therefore,In order to provide measurement data support for wastewater discharge monitoring and process control,the article adopts filter weighing method for uncertainty of error of the instrument.
