A solar ventilation system device for remediation of contaminated sites

Abstract

The invention provides a solar ventilation system device for remediation of a contaminated site. The device comprises a solar power supply control system, and an aeration system and an air extraction system, which are distributed in a soil remediation area, wherein the solar power supply control system is used for collecting solar energy and discharging the solar energy to the aeration system and the air extraction system for use; the aeration system is used for delivering air to the soil remediation area; the air extraction system is used for extracting organic contaminants from the soil remediation area. According to the device, the solar energy is adopted for power generation, so that electric energy is effectively saved, and constraints of cost such as the landform and electric wires are broken; soil vapor extraction and ventilation remediation technologies are coupled to rapidly and effectively remove volatile organic matters and biodegradable organic matters in soil; the soil can be safely reutilized after quality improvement and purification; the device is convenient to mount, wide in application range, flexible in operation, lower in running cost and free of secondary pollution.

Description

technical field [0001] The invention belongs to the technical field of remediation of sites polluted by organic pollutants, and in particular relates to a solar ventilation system device used for remediation of polluted sites. Background technique [0002] Soil is an important part of the human ecological environment. With the acceleration of urbanization and the rapid development of modern industry and agriculture, more and more smelting and organic chemical industry relocation sites have been replaced by urban planning. The organic pollutants caused by the phenomenon enter the soil, which not only destroys the ecosystem of the soil itself, but also poses a threat to groundwater resources. In addition, the pollution and leakage of oil extraction, smelting, use and transportation, and the discharge of oily wastewater have also become the focus of the current international soil ecological environment protection and governance, and have increasingly attracted widespread attent...

Problems solved by technology

For the treatment of such volatile organic pollutants, chemical oxidation methods are often used to remove them, but chemical oxidation methods are likely to cause secondary pollution due to chemical reactions during the treatment process

In order to solve the problem of secondary pollution, physical extraction methods are used in this field, but the phenomenon of "tailing" often occurs in physical extraction, resulting in that pollutants cannot be effectively removed. In addition, the existing physical extraction methods The energy comes from the grid, and the cost of using the grid is relatively high, and it is not in harmony with the natural environment, so there are certain limitations
