Embodiment 1

[0050] Such as figure 1 As shown, a device for repairing rock formation environmental pollution by using nanotechnology of the present invention includes a water injection well 1. The number of the water injection wells is 1 to 4 (2 in this embodiment), and the depth of the water injection well is 5 to 15 meters (8 meters and 15 meters in this embodiment), and the water injection wells are provided with pumping wells 2 at intervals of 5 to 10 meters along the direction of the groundwater flow ( figure 1 The direction of the horizontal arrow in the soil is the direction of groundwater flow);

[0051] A nanobubble saturated solution injection component A is provided on the ground between the water injection well 1 and the pumping well 2, and the nanobubble saturated solution injection component is connected to the water injection well and the pumping well pipeline respectively;

[0052] Filters B are arranged in the water injection well 1 and the pumping well 2.

[0053] The nanobubble...

Embodiment 2

[0070] For a small area of ​​soil or groundwater pollution area, a single set of the device of the present invention for repairing rock formation environmental pollution by using nanotechnology can be provided, and a better rock formation environment restoration effect can also be achieved.

[0071] Such as figure 2 As shown, a device of the present invention that uses nanotechnology to repair the environmental pollution of rock formations is installed and applied in the same manner as described in the above-mentioned embodiment 1, to carry out soil or groundwater pollution treatment on the environment of deep and shallow rock formations.

[0072] In addition, if you need to deal with surface pollution, you can also directly spray a saturated solution with nanobubbles.

[0073] The device and application of the present invention for repairing rock formation environmental pollution by using nanotechnology have low cost, good repair effect, high repair efficiency, complete treatment w...

Abstract

A device for remediating rocks environmental pollution by a nanotechnology and an application thereof are disclosed. A pumping well is arranged 5-10m away from a water injection well along the flowing direction of subsurface flow. A filter screen is arranged in both the water injection well and the pumping well. A nanobubble saturated solution injection assembly is arranged on the ground between the water injection well and the pumping well. The nanobubble saturated solution injection assembly is respectively connected with the water injection well and the pumping well through pipelines. Through a nanobubble saturated solution, rocks environmental pollution is processed. The device provided by the invention has advantages of low cost, good remediation effect and high remediation efficiency. In addition, processing is thorough and secondary pollution is not caused; organic pollutants and heavy metal pollutants in underground water and saturated soil areas below the underground water can be removed effectively; and only by arranging corresponding numbers of the water injection wells and the pumping wells with cooperation of one or more sets of equipment, the device can be applied in the field of pollution treatment of rock soil and underground water with different pollution sources, different pollution areas, different pollution degrees and different pollution depths.

Description

Technical field [0001] The present invention relates to the field of soil and groundwater pollution treatment and restoration, and in particular to a method for repairing organic matter and heavy metal pollution in the rock formation environment, which contains single or multiple reaction gases, and the reaction gases are present in a saturated liquid in the form of nano bubbles Processing device and its application processing method. Background technique [0002] With the acceleration of China’s urbanization, industrialization process, and rapid economic development, industrial production is also increasingly polluting the surrounding environment, especially the pollution of soil and groundwater, which has a severe form of development from urban to rural areas. The data shows : China has 20 million hectares of arable land polluted by heavy metals, of which 2 million hectares are polluted by mining areas, 5 million hectares are polluted by oil, 10 million hectares are polluted by...
