A device and application for repairing environmental pollution in rock formations using nanotechnology

Abstract

A device and application for repairing environmental pollution in rock formations using nanotechnology. Injection wells are provided with pumping wells at intervals of 5 to 10 m along the direction of groundwater flow, and filter screens are arranged in the water injection wells and pumping wells. A nano-bubble saturated solution injection component is arranged on the ground between them, and the nano-bubble saturated solution injection component is respectively connected to the water injection well and the pumping well pipeline, and the environmental pollution of the rock formation is treated through the nano-bubble saturated solution. The invention has low cost, good repairing effect, high repairing efficiency, complete treatment without secondary pollution, and can effectively remove various organic pollutants and heavy metal pollutants in groundwater and its subsaturated soil area, and only needs to set up A corresponding number of water injection wells and pumping wells, combined with one or more sets of devices, can be used in the field of soil and groundwater pollution treatment in different pollution sources, different pollution areas, different pollution degrees, and different pollution depths.

Description

technical field [0001] The invention relates to the field of soil and groundwater pollution treatment and restoration, in particular to a method for repairing organic matter and heavy metal pollution in the rock formation environment, which contains a single or multiple reaction gases, and the reaction gases are present in saturated liquids in the form of nano-bubbles. Processing device and its application processing method. Background technique [0002] With my country's urbanization, the acceleration of industrialization, and the rapid development of the economy, the pollution of the surrounding environment by industrial production is becoming more and more serious, especially the pollution of soil and groundwater, which has a severe form of development from urban to rural areas. Data shows : In my country, 20 million hectares of arable land have been polluted by heavy metals, of which 2 million hectares have been polluted by mining areas, 5 million hectares have been pollu...
