Embodiment 1

[0072] The contaminated soil repaired in this embodiment is the oil-contaminated soil configured in the laboratory. The soil collected is loam, which is passed through a 2mm sieve after natural air-drying in the room. 35g / kg oil pollutes the soil. The prepared soil was naturally air-dried for 7 days, and the moisture content was adjusted to 20% with deionized water. It was divided into 3 treatments, namely, control, electric repair and compensation field strength electric repair, and were respectively loaded into the restoration device (length 20cm × width 20cm × height 10cm).

[0073] Such as figure 1 As shown, the contaminated soil remediation device is a 2×2 electrode arrangement, the electrode material is graphite, the diameter Φ=1cm, the height is 11cm, and the applied voltage is 20V. Such as figure 2 As shown, the polarities of the two adjacent electrodes are kept opposite, and the opposite polarities of the two electrodes are the same. The electrode polarity switch...

Abstract

The invention relates to an electrokinetic remediation visual system for organically polluted soil. The system comprises a parameter monitoring module, an information processing module and a visual module. By designing a technical process of multi-factor online monitoring-same frequency numerical value conversion-spatial position association-dot matrix data display, two-dimensional visualization of electrokinetic remediation of organically polluted soil is achieved, so that space-time regulation of the remediation process is facilitated and the total remediation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of electrodynamic restoration of organic polluted soil, in particular to a visualization system for electrodynamic restoration of organic polluted soil. Background technique [0002] Electric remediation is an emerging technology for contaminated soil treatment. Different from the electrokinetic directional migration / enrichment principle of heavy metal polluted soil, the electrokinetic remediation process of organic polluted soil is more complicated. The degradation of organic pollutants is jointly affected by electrokinetic chemical oxidation and microbial degradation, and is restricted by soil environmental factors. [0003] The research and development of electrodynamic technology for organic polluted soil has been focused on three aspects: (1) electrode development and layout optimization (ZL201110203862.0, ZL201310595675.0, ZL 201110439187.1, 201610562782.7), (2) adapting to electrodynamic conditions ...
