Problems solved by technology

[0004] Due to the difference in the composition of polluted water, pollutant types, properties, etc., especially in the case of compound pollution where different pollutants exist at the same time, it is often difficult for a single repair technology to achieve the repair goal. Therefore, a combined application device and repair method of repair technology has been developed. , to repair heavy metal polluted water, which is of great significance

Embodiment 1

[0035] Such as figure 1 As shown, a heavy metal polluted water remediation device includes an anode pool 1 and a cathode pool 2, an electrode anode and an electrode cathode are respectively placed in the anode pool and the cathode pool, and the electrode anode and the electrode cathode are connected to a DC power supply and form a loop; An osmosis reaction wall is arranged between the anode pool and the cathode pool, and the osmosis reaction wall includes a floating bed 3 floating on the water surface, a sinking bed 4 sinking into the bottom of the water, and a osmosis wall 5 connecting the floating bed and the sinking bed.

[0036] The basic principle of EKR-PRB coupling repair technology is to use electromotive force to move highly toxic heavy metals and organic substances to both ends of the electrode, so that the pollutants can fully react with the filler matrix in the permeable reaction wall, and be removed or degraded into toxic substances by adsorption. Lower low-priced...

Abstract

The invention belongs to the technical field of sewage treatment, and particularly relates to a heavy metal polluted water remediation device. The remediation device comprises an anode pool and a cathode pool, an electrode anode and an electrode cathode are placed in the anode pool and the cathode pool respectively, and the electrode anode and the electrode cathode are connected with a direct-current power source to form a loop. A permeable reactive barrier is arranged between the anode pool and the cathode pool and comprises a floating bed floating on the water surface, a sinking bed sinkinginto the water bottom and a permeable wall for connecting the floating bed and the sinking bed. According to the device, the electrodynamic remediation technology and the permeable reactive barrier technology are combined to remediate heavy metal polluted water, heavy metal pollutants in underground water can be effectively removed in situ, and the device has the advantages of being small in investment, quick in effect and the like.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a repairing device for heavy metal polluted water. Background technique [0002] Water resources are indispensable resources for human survival, and water resources have a huge impact on residents' lives and industrial production. However, due to some man-made or natural reasons, heavy metals enter the lake water through seepage, overflow and runoff. Heavy metal pollutants can not only cause serious harm to people's health, but also cause serious damage to the surrounding soil environment, animals, and vegetation. [0003] In the prior art, the remediation technology of polluted water includes extraction technology, air lift technology, air stripping technology, biological remediation technology, osmotic reaction wall technology, in-situ chemical remediation and so on. Among them, electrokinetic remediation technology (EKR) and permeable wall technology (PR...
