GPS技术在铅锌尾矿污染土壤修复检测中的应用研究

Application of GPS Technology in Remediation Detection of Lead-Zinc Tailings Contaminated Soil

文章采用GPS技术对修复结果进行检测,通过分析铅锌尾矿污染的特点及污染程度评定,得知其有害化学元素组成及含量限值,通过创建污染源坐标、对流-弥散方程以及单宽水流量方程组,探究污染物的土壤迁移与雨水地表径流扩散方式,从而对污染土壤修复结果实施基于GPS技术的检测策略;GPS框架中的单片机利用串行总线,将脉冲个数差与温度值传到GSM模块上,通过上位机和BP神经网络的处理,最终实现污染土壤的修复检测。仿真实验表明,GPS技术拥有更好的应用前景与使用空间,更加适用于污染土壤修复检测,且具有理想的精准性。

By analyzing pollution characteristics of lead and zinc tailings and assessment of pollution degree,the harmful chemical element composition and content limit were known.By creating pollution source coordinates,convection-dispersion equations and single-wide water flow equations,we will explore the soil migration of pollutants and the way of rainwater surface runoff diffusion.Therefore,the GPS-based detection strategy is implemented for the contaminated soil remediation results;the single-chip microcomputer in the GPS frame uses the serial bus to transmit the pulse number difference and temperature value to the GSM module,which is finally processed by the host computer and BP neural network Remediation testing of contaminated soil.Simulation experiments show that GPS technology has better application prospects and use space,is more suitable for contaminated soil remediation detection,and has ideal accuracy.
