Embodiment 1

[0028] A vertical device for electrically repairing heavy metal-contaminated soil 112, the vertical device comprising:

[0029] A treatment box 1, the material of the treatment box 1 is a lead plate, the treatment box 1 is provided with a water outlet 111 and a water inlet, and the treatment box 1 includes:

[0030] Specifically, the water outlet 111 is used for water outlet, and the water inlet is used for water intake. The purpose of the water inlet and outlet is to carry away the heavy metal ions electrolyzed in the soil 112, so that the soil 112 is repaired; the water outlet 111 is set corresponding to the cathode 3, The water inlet is set corresponding to the anode 2. When the anode 2 is set in multiple places, the water distribution pipe 6 is added to complete the targeted water distribution of the anode 2; and the water inlet can be adjusted. Generally speaking, the water outlet 111 is set at the bottom of the box body 11, and the water inlet is set on the end cover 12;...

Embodiment 2

[0064] On the basis of Embodiment 1, do further optimization, specifically:

[0065] When repairing the soil 112 with a low degree of pollution, in consideration of energy consumption and efficiency, the way that the water outlet 111 is at the bottom and the water inlet is at the top can be adopted.

[0066] The middle part of the end cap 12 protrudes outwards and is conical.

[0067] By optimizing the shape of the end cap 12, after the electrolysis generates heat, the water evaporates upwards, and the water vapor moves upwards along the inner wall of the end cap 12. Since the end cap 12 is conical, the water vapor will gradually cool and gather at the center top of the end cap 12. The water droplets, after gathering to a certain extent, become water droplets and fall towards the middle of the accommodating space, that is, fall towards the cathode 3, so that the moisture of each part of the soil 112 can be improved by using water evaporation, so that the original water distrib...

Abstract

The embodiment of the invention provides an electrokinetic remediation vertical device for heavy metal contaminated soil, and belongs to the technical field of soil remediation. The electrokinetic remediation vertical device for the heavy metal contaminated soil comprises a treatment tank made of a lead plate, wherein the treatment tank comprises a tank body, an end cover, an electrode plate and awater treatment assembly; a holding space is arranged in the tank body and can be used for holding soil and liquid contaminated by heavy metal; the end cover is arranged on the tank body; the water treatment assembly can be used for treating the liquid containing heavy metal ions; an input end and an output end of the water treatment assembly communicate with the holding space; the electrode plate can enable the heavy metal to electrolyze into the heavy metal ions under the action of a power supply; and the heavy metal ions move from the holding space to the water treatment assembly through acathode. The technical effects on conveniently collecting the heavy metal ions and improving a radiation protection capacity of the electrokinetic remediation device are achieved.

Description

technical field [0001] The invention relates to the technical field of soil restoration, in particular to an electric restoration vertical device for heavy metal polluted soil. Background technique [0002] At present, the electric repair device mainly relies on two electrode plates, the cathode and the anode, to electrolyze the soil, so that the heavy metal ions in the soil are electrolyzed, and the precipitated heavy metal ions are collected; after the soil is electrolyzed to a certain extent, The content of heavy metal ions in the soil reaches the standard, and the restoration of heavy metal-contaminated soil is completed. [0003] However, the existing electric restoration devices have low collection efficiency for heavy metal ions. Generally, the heavy metal ions are adsorbed and gathered together. After the electrolysis is completed or in the middle of the electrolysis, the soil enriched in the heavy metal ion accumulation area is taken out to make the remaining soil ...
