Application and Optimization of 5-Day BOD Dilution in Water Pollution Monitoring

本文针对水污染监测中五日生化需氧量(BOD5)稀释倍数的应用与优化进行了研究。通过对水体中有机物质的分解过程,BOD5可反映水体污染程度,是评估水质的重要指标之一。稀释倍数的选择对于BOD5测定结果的准确性和实用性至关重要。本研究从理论和实践角度出发,探讨了不同稀释倍数对BOD5测定结果的影响,并优化了稀释倍数的选择方法。研究结果表明,在保证测定结果准确性的前提下,适当增加稀释倍数可以提高实验效率,降低成本。同时,本文还分析了稀释倍数与水样特性、环境因素等的关系,并提出了在实际应用中优化稀释倍数的建议。通过本研究的应用与优化,可为水污染监测工作提供技术支持和决策依据。

In this paper,the application and optimization of the 5-day BOD(BOD5)dilution ratio in water pollution monitoring were investigated.Through the decomposition process of organic matter in the water,BOD5 reflects the pollution level of the water body and is one of the important indexes to evaluate water quality.Selection of dilution ratio is important for the accuracy and practicality of BOD5 determination.From the perspectives of theory and practice,the effect of different dilution ratios on the BOD5 determination was discussed,and the selection of dilution ratio was optimized.The results show that under the premise of ensuring the accuracy of the determination,increasing the dilution ratio can improve the experimental efficiency and reduce the cost.At the same time,the paper also analyzes the relationship between dilution ratio and water sample characteristics and environmental factors,and puts forward some suggestions for optimizing dilution ratio in practical application.The application and optimization of this study can provide technical support and decision basis for water pollution monitoring.
