污染转移效应的水体重金属污染物检测技术研究

Detection Technology of Heavy Metal Pollution in Water Body Considering Pollution Transfer Effect

针对目前水资源污染难以定位管控问题,提出一种重金属污染物检测方法。结合水体流速、溶解因子、污染物的迁移率以及土壤的积水含量,计算该介质在各检测点上的吸附数值。以此数值为判定标准,建立等位线浓度定位区域,将各组检测样本放置于各个等位线附近,通过污染转移效应和介质参数判定污染物存在的等位线,完成重金属污染检测。仿真实验证明,所提方法对既定区域内水平及竖直位置的污染点检测定位准确、距离计算结果精准,算法具有较高的实用性及可参考性。

This paper proposed a detection method for heavy metal pollutants to address the difficulties in locating and controlling water resources pollution.The adsorption value of the medium at each detection point is calculated according to the water flow rate,dissolution factor,pollutant mobility and soil ponding content.Taking this value as the judgment standard,the paper established the equipotential concentration positioning area,placed each group of test samples near each equipotential line,judged the equipotential line of pollutants through pollution transfer effect and medium parameters,and complete the detection of heavy metal pollution.Simulation results show that the proposed method can detect and locate the pollution points at the horizontal and vertical positions in the given area accurately.The distance calculation results are accurate,and the algorithm has high practicability and reference.
