基于现场传感技术的矿区重金属实时监测研究

Study on Real Time Monitoring of Heavy Metals in Mining Area Based on Field Sensing Technology

黄石作为矿冶工业密集性城市,土壤中重金属污染现象比较严重。传统的异位检测法成本较高。通过分析比较各类传感器,得出基于MEA(Microelectrodes Array,微电极阵列)的伏安法可有效、实时地反映土壤污染程度;讨论了浸出液形成条件,并提出了传感器分布及组网管理方案,为实时动态的分析掌握环境数据提供了一种可行手段。

As an intensive mining industrial city, Huangshi has more serious pollution of heavy metal in soil. Traditional methods such as the malposition method has high cost. Through the analysis and comparison of va- rious kinds of sensors, the method based on the MEA voltammetry can effectively and simultaneously reflect the degree of soil pollution. The leaching liquid forming conditions are discussed, the sensor distribution and network management scheme are put forward, which provides a feasible method for the analysis of the real - time dynamic environment data.
