Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings.

[0030] like figure 1 , a solar energy-enhanced bio-ventilation system for remediating soil organic matter pollution, including a solar heat collection system, a ventilation system, a nutrient solution injection system, a pollutant vacuum extraction system, and a gas purification device. The solar heat collection system uses a trough solar collector 9. Set fan 5 and valve 1 on the front end pipeline of trough solar collector 9, set valve 2 on the back end pipeline of trough solar collector 9, valve 2 is connected with fan 6, and at the outlet of fan 6 There is a valve 4 at the end, and the fan 6 is connected to the ventilation pipe 10. The above-ground part of the ventilation pipe 10 is covered with an insulation layer. The pipe below a certain depth on the ground is a porous heat-dissipating ventilation pipe. The air is reasonably and evenly distributed into the pollu...

Abstract

The invention relates to a solar hot air system enhanced in-situ bio-ventilation soil restoration system. The system comprises a solar air heat collection system, a ventilation system, a contaminant vacuum extraction system and a gas purification system. The ventilation system is a ventilation pipeline, and the solar air heat collection system is connected with the ventilation pipeline and used for heating air in the ventilation pipeline. The contaminant vacuum extraction system comprises a gas phase extraction pipe and a vacuum pump, the gas phase extraction pipe is directly buried in the heated contaminated soil area, and the upper portion of the gas phase extraction pipe is connected with the gas purification device. The solar hot air system enhanced in-situ bio-ventilation soil restoration system further comprises a nutrient solution injection system, and a nutrient solution is evenly pumped into organic matter contaminated soil through the nutrient solution injection system. According to the system, solar energy serves as a heat source, heated air is injected into a soil embedded radiating pipe, soil temperature is adjusted, soil microbial flora and the nutrition environment are optimized, degradation of microorganisms for organic matter in the contaminated soil is promoted, and then following vacuum extraction is facilitated. By means of the system, energy is saved, the emission of greenhouse gas is reduced, and secondary pollution generated by combustion of fossil fuel is avoided.

Description

technical field [0001] The invention belongs to the technical field of environmental restoration, and in particular relates to a solar hot air system enhanced in-situ biological ventilation soil restoration system. Background technique [0002] Today, with the rapid development of China's economy, the problem of soil pollution is becoming more and more prominent. The "running, leaking, dripping, and leaking" of many chemical plants, oil extraction fields, gas stations, raw material tank farms and other facilities have caused the land to be seriously polluted by petroleum hydrocarbons and other organic compounds, which remain in the soil or migrate to the atmosphere or groundwater Among them, polluting the ecological environment will cause direct or indirect harm to human life and health. The land after the relocation of the enterprise cannot be developed. In recent years, accidents caused by improper disposal of polluted land abound. Therefore, the restoration and treatmen...
