specific Embodiment

[0034] Specific embodiment: use above-mentioned a kind of step that is used for the remediation process device of slightly polluted groundwater to comprise:

[0035] 1) Open the water inlet valve, and the slightly polluted groundwater that needs to be repaired enters the device.

[0036] 2) Connect the industrial DC power supply, turn on the UV lamp, and turn on the spray gun. The plasma sprayed by the spray gun enters the container for storing the plasma, and then shoots out from the small hole of the container to activate the surface of the photocatalyst.

[0037] 3) In nanoscale TiO 2 Under the catalysis of photocatalyst, the photocatalytic oxidation treatment is carried out on the slightly polluted groundwater. The plasma can activate the surface of the photocatalyst to ensure that the activity of the photocatalyst decreases very slowly.

[0038] 4) Open the water outlet valve, and the repaired complete water is discharged from the water outlet.

Abstract

The invention specifically provides a remediation technological device for micro-polluted underground water. The remediation technological device comprises a cylindrical shell, a plasma oxidation device, a photocatalyst, an ultraviolet lamp and a quartz glass protection cover. A spraying gun of the plasma oxidation device is used for transmitting plasmas sprayed by the spraying gun to a plasma cylindrical container through a pipeline; the plasma storage cylindrical container is arranged in an inner cavity of a cylindrical shell in a sleeving manner; a space is formed between an inner side wallof the cylindrical shell and an outer side wall of the plasma storage cylindrical container; a columnar cavity formed by the inner side wall of the plasma storage cylindrical container is a repairinggroove body for treating the micro-polluted underground water. The photocatalyst is arranged in the space between the outer side wall of the plasma storage cylindrical container and the inner side wall of the cylinder. The ultraviolet lamp sleeves a central shaft of the plasma storage cylindrical container. According to the device provided by the invention, the surface of the photocatalyst can beactivated through the plasmas, so that the lowering speed of the activity of the photocatalyst is greatly reduced. Therefore, the number of times of replacing the photocatalyst can be reduced and theworking time is saved.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a restoration process device for slightly polluted groundwater. Background technique [0002] Groundwater pollution mainly refers to the phenomenon that the chemical composition, physical properties and biological characteristics of groundwater are changed due to human activities, resulting in a decrease in quality. The sources of groundwater pollution mainly include: industrial waste water discharged directly underground, polluted surface water intruding into underground aquifers, human and animal feces or polluted water due to excessive use of pesticides seeping into the ground, etc. Among them, agricultural pollution has the characteristics of a large amount and a wide range. Incompletely utilized nitrogen fertilizers are converted into nitrate and nitrite through biological or chemical processes when passing through the strata, and then seep into groundwater. Long-term drinkin...
