Device for remediating rocks environmental pollution by nanotechnology and application thereof

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...
