Embodiment Construction
[0036] The present invention will be further described with reference to the accompanying drawings.
[0037] Such as figure 1As shown, an in-situ repair and treatment system for heavy metal-contaminated groundwater includes a submersible pump 1 , a filter 2 , a reactor 3 , a resin reaction wall 4 and an electrodialysis box 5 .
[0038] Such as figure 1 As shown, a suction pipe 6 is inserted in the underground water, and the submersible pump 1 is positioned at the upper end of the suction pipe 6, and the groundwater is pumped to the ground by the suction pipe 6. The filter 2 is a centrifugal screen filter 2 . A first pipe 7 is provided between the inlet of the filter 2 and the outlet of the submersible pump 1 , and a valve is arranged on the first pipe 7 .
[0039] Such as figure 1 As shown, the reactor 3 is a box. And the electrodialysis box 5 is located above the reactor 3 . A water inlet 8 and a water outlet 9 are respectively opened on both sides of the reactor 3 alon...

The invention discloses a heavy metal polluted underground water in-situ remediation management system. The heavy metal polluted underground water in-situ remediation management system comprises a submersible pump for pumping underground water, a filter, a reactor, resin reaction walls and an electrodialysis box, the electrodialysis box is located at the upper part of the reactor, the resin reaction walls penetrate through the reactor and the electrodialysis box, and are slidably connected to the reactor and the electrodialysis box, each resin reaction wall is provided with a driving mechanism for driving the resin reaction wall to slide, anion-cation exchange membranes are respectively arranged at two side surfaces of each resin reaction wall in the electrodialysis box, two sides of the resin reaction walls are provided with an anode plate and a cathode plate disposed in the electrodialysis box, and a power supply for powering the anode plate and the cathode plate is arranged in the electrodialysis box. The underground water is pumped by the submerged pump, and after mud and sand are removed by the filter, the water enters the reactor. After the underwater passes through the resin reaction walls, the resin reaction walls adsorb nitrates in the underground water, so that the underground water is remedied, the treated underground water flows out of the reactor and is returned to the underground position, and the management is completed.
Description
technical field [0001] The invention relates to groundwater treatment, in particular to an in-situ repair and treatment system for groundwater polluted by heavy metals. Background technique [0002] Groundwater is one of the important freshwater resources. It plays an irreplaceable role in the process of human life and production, and is a solid foundation for human survival and social development. However, with the development of industry in recent years, more and more poisonous and harmful substances such as chemical organics and heavy metals are entering the groundwater system through various channels, polluting the groundwater resources that human beings depend on for survival. Therefore, the restoration and treatment technology of groundwater has been prepared. It has attracted the attention of researchers at home and abroad. [0003] At present, the most commonly used heavy metal-contaminated groundwater remediation technologies at home and abroad mainly include: ex-s...
