摘　　要：因为浊度对紫外波长的光强具有一定的吸收能力,而目前国内用使用的总磷在线自动监测仪的监测方法是以国标钼酸铵分光光度法为基础的,所以在水质的监测过程,浊度会对总磷在线监测仪的监测长生较大的干扰,对监测数据结果有较为明显的影响,是最后的分析结果产生较大的偏差。所以,文章选择两种市场份额占比较高的总磷在线自动监测仪,选取不同浊度的试样进行监测试验,然后与实验室的手工测量分析数据进行比较,分析浊度对总磷在线自动监测仪测量值得相关性,实验结果表明,总磷在线自动监测仪的监测结果和浊度呈现明显的相关性,当浊度较高时,自动监测仪的结果偏差也相对较大,浊度较低时,自动监测仪的监测结果与实验室的测量值基本一致。Because turbidity has a certain absorption capacity to the light intensity of ultraviolet wavelength,and the monitoring method of total phosphorus online automatic monitor used in China is based on the national stan⁃dard ammonium molybdate spectrophotometry,so in the process of water quality monitoring,turbidity will have a greater interference on the monitoring of total phosphorus on-line monitoring instrument,and has a more obvious impact on the monitoring data results,causing a greater deviation in the final analysis results.Therefore,this paper selects two kinds of online automatic total phosphorus monitors with high market share,selects samples with differ⁃ent turbidity for monitoring test,and then compares with the manual measurement and analysis data of the laborato⁃ry,analyzes the correlation between turbidity and the online automatic monitoring instrument of total phosphorus.The experimental results show that the monitoring results of online total phosphorus automatic monitor and turbidi⁃ty present a clear correlation.When the turbidity is high,the result deviation of the automatic monitor is relatively large.When the turbidity is low,the monitoring result of the automatic monitor is basically consistent with the mea⁃sured value in the laboratory.
