影响水质监测中现场水质采样质量的因素及对策

Factors and countermeasures affecting the quality of on-site water quality sampling in water quality monitoring

随着工业化进程的加快,水质污染的情况越来越严重,为更好了解水质现状,水质监测就显得尤为重要,水质监测由水质采样和实验室分析两大部分组成,科学规范的采样可以确保水质样品的代表性、准确性。合理规范的采样可以保证水质样品的准确性。在实际现场水质采样过程中,会有很多因素影响采样的质量,为保证水质采样质量,文章从采样设备、采样流程、人为操作、外部环境等四个方面分析了影响因素,在此基础上提出应注意设备的选择与维护,规范采样流程,提高相关工作人员工作能力,做好采样准备工作等四条对策。

With the acceleration of industrialization,water pollution is becoming more and more serious.In order to better understand the current status of water quality,water quality monitoring is particularly important.Water quality monitoring consists of two parts:water quality sampling and laboratory analysis.It can ensure the representativeness and accuracy of water quality samples.Reasonable and standardized sampling can ensure the accuracy of water quality samples.In the actual on-site water quality sampling process,there will be many factors that affect the quality of the sampling.In order to ensure the quality of the water quality sampling,this paper analyzes the influencing factors from four aspects:sampling equipment,sampling process,human operation,and external environment.Attention should be paid to the selection and maintenance of equipment,standardizing the sampling process,improving the working capacity of relevant staff,and preparing for sampling.
