环境监测中废水监测质量控制方法研究

Study on Quality Control Methods of Wastewater Monitoring in Environmental Monitoring

目前,在环境监测中,废水监测质量控制方法应用时,测定值与废水实际参数值相差较大,造成质量评定达标率低。因此,有必要开展环境监测中废水监测质量控制方法研究。本文通过分析环境监测中废水监测流程,从废水监测仪器精度校准、控制待监测水体样本溶液制备误差、废水监测结果复核三方面入手,提出一种全新的质量控制方法。试验证明,该方法与传统方法相比精度更高,质量达标率可达100%,保证环境监测站的综合质量提升。

At present,in environmental monitoring,when the wastewater monitoring quality control method is applied,the measured value and the actual parameter value of the wastewater are quite different,resulting in a low rate of quality assessment.Therefore,it is necessary to carry out research on wastewater monitoring quality control methods in environmental monitoring.This paper analyzes the wastewater monitoring process in environmental monitoring,starts with three aspects,namely calibration of wastewater monitoring instrument accuracy,control of sample solution preparation errors of the water to be monitored,and review of wastewater monitoring results,and proposes a new quality control method.Tests have proved that this method has higher accuracy than traditional methods,and the quality compliance rate can reach 100%,ensuring the overall quality improvement of environmental monitoring stations.
