摘要
科学、便捷的获得污染物在地下水中运移的时空变化规律,不仅有利于地下水污染防治,还能为区域规划提供科学可靠的依据。以四川省德阳平原地区为例,以胭脂红为示踪剂,通过野外径向弥散试验,采用标准曲线法求解弥散系数,并通过Matlab编程计算实测浓度与标准曲线浓度之间的误差,得到纵向弥散系数为0.53m2/h,均方根误差为0.066 3。可见获得的弥散系数较为合理,弥散试验结果可信。
To obtain the spatial and temporal variation of pollutants accurately in groundwater is of great importance to prevent and control pollution.It also provides scientific basis for regional planning.A radial dispersion test with carmine as tracer agent was conducted in the plain of Deyang,Sichuan Province.Standard curve fitting method was used to solve dispersion coefficient.The root-mean-square errors between the measured points and the standard curve were calculated by MATLAB.Ultimately,the vertical dispersion coefficient is 0.53m2/h,and the RMS error is 0.066 3.The results show that the dispersion coefficient is reasonable and the test is reliable.
