Electrokinetic remediation contaminated soil display system

Abstract

The invention discloses an electrokinetic remediation contaminated soil display system. The system comprises a detection subsystem, a real-time sampling subsystem, a transmission subsystem, a treatment subsystem, a display subsystem, a recording and storing subsystem and a feedback subsystem. By means of the electrokinetic remediation contaminated soil display system, multiple sensors are effectively integrated, detection, displaying and storing of electric field intensity, pH, Eh, moisture content, temperature and soil interstitial water heavy metal concentration at any position in an electrokinetic remediation treatment box can be achieved, and the later-period data processing is facilitated. The electrokinetic remediation contaminated soil display system is of great significance in knowing soil remediation conditions, improving electrokinetic remediation efficiency, reducing manual work amount for monitoring soil remediation and reducing maintaining cost.

Description

technical field [0001] The invention belongs to the technical field of remediation of heavy metal polluted soil. Specifically, it relates to a display system for electrically remediating polluted soil. Background technique [0002] Studies have shown that soil pollution in my country is mainly caused by heavy metal pollution, among which cadmium, mercury, lead, arsenic and other pollution are the most prominent. For example, tens of thousands of hectares of land in my country are currently polluted by cadmium and mercury. At present, the main factors causing soil heavy metal pollution are: mining activities, stacking of wastes containing heavy metals, dry and wet deposition of dust containing heavy metals, discharge of waste water containing heavy metals, irrigation of farmland sewage and sludge fertilization, etc. Because heavy metals are not easy to decompose, transform and enrich after entering the soil, and the structure of the soil system itself is complex, it is very ...
