水体中悬浮颗粒物对总磷自动监测仪测试的影响

Influence of Suspended Particles in Water on the Test of Total Phosphorus Automatic Monitor

为保障自动监测数据的准确性,提升水质自动监测系统中水样前处理效果,对几种常用的预处理方式进行比较,分析了低浊度时预处理方式及颗粒物成分对总磷测试的影响,对比不同预处理方式对监测数值的影响、总磷自动监测仪测试数据与实验室监测测试数据的差异,减少水体中悬浮颗粒物对总磷自动监测仪测试的影响。

In order to ensure the accuracy of automatic monitoring data and improve the water sample pretreatment effect in the automatic water quality monitoring system,several common pretreatment methods are compared,the effects of pretreatment methods and particle composition on total phosphorus test at low turbidity are analyzed,and the effects of different pretreatment methods on monitoring values are compared.The difference between the test data of total phosphorus automatic monitor and laboratory monitoring test data can reduce the impact of suspended particles in water on the test of total phosphorus automatic monitor.
