摘要
复电阻率特性对水体中的物质、含量等能较好的识别,通过复电阻率特征可以分析和测量来识别水质的变化和污染情况。为了了解降雨对人工湖水体的复电阻率特征影响,用以判断人工湖水体的污染情况与污染范围,以宿州学院校内人工湖为例,分别采集了饮用水、下雨前人工湖湖水、下雨后人工湖湖水三种水质情况不同的水进行实验,分别测量了三种水体的复电阻率的电导率、相位与幅值,比较测量结果的电导率、幅值和相位差异。结果表明,人工湖湖水与饮用水复电阻率相比相差明显,人工湖水体的相位与幅值均小于饮用水的相位与幅值,雨后人工湖水体与雨前人工湖水体复电阻率特性发生变化,降雨之后的人工湖水体的电导率和幅值都增大。研究显示,降雨会影响人工湖水体的复电阻率特性,使人工湖水体的幅值和电导率增大,减轻人工湖水体的污染程度。
The complex electrical resistivity characteristics can effectively identify substances and contents in water bodies. By analyzing and measuring the complex electrical resistivity characteristics, changes in water quality and pollution can be identified. In order to understand the impact of rainfall on the complex electrical resistivity characteristics of artificial lake water, and to determine the pollution situation and scope of artificial lake water, taking the artificial lake in Suzhou University as an example, experiments were conducted on three different water quality conditions: drinking water, artificial lake water before rain, and artificial lake water after rain. The conductivity, phase, and amplitude of the complex electrical resistivity of the three water bodies were measured, and the conductivity of the measured results were compared amplitude and phase differences. The results show that there is a significant difference in the complex resistivity between artificial lake water and drinking water. The phase and amplitude of the artificial lake water are both smaller than those of drinking water. The complex resistivity characteristics of the artificial lake water after rain and before rain change, and the conductivity and amplitude of the artificial lake water after rainfall increase. Research has shown that rainfall can affect the complex electrical resistivity characteristics of artificial lake water bodies, increase the amplitude and conductivity of artificial lake water bodies, and reduce the pollution level of artificial lake water bodies.
