Inflatable greenhouse applicable to contaminated site

Abstract

The invention relates to an inflatable greenhouse applicable to a contaminated site. The inflatable greenhouse comprises a greenhouse shaped air film, fixing piles are arranged at the edge of the airfilm, a plurality of steel wire ropes are arranged outside the air film, and two ends of any one of the steel wire rope are connected with the corresponding fixing piles. Air inlet equipment is arranged on one side of the greenhouse, and a circulating tail gas discharging system is arranged on the other side of the greenhouse. The lateral side of the greenhouse is provided with access ports, and the circulating tail gas discharging system is connected with a controller. By consideration of harms to physical health of onsite workers and surrounding residents due to proneness of toxic and harmful gases and malodorous gases to volatilization and dispersion into surroundings in a contaminated site treatment process and consideration of particularity of site remediation construction, special utilization of the inflatable greenhouse is provided, the problem of odor dispersion in an excavation and remediation process of the organic contaminated site is effectively solved, smoothness and safety in site remediation are guaranteed, the circulating tail gas discharging system is safe and environmentally friendly, and convenience in use, mounting, demounting and storage and recyclability are realized.

Description

Technical field [0001] The invention belongs to the technical field of the regeneration of contaminated soil, and particularly relates to a multifunctional inflatable greenhouse suitable for contaminated sites for remediation of contaminated sites. Background technique [0002] With the acceleration of my country’s urbanization process and the implementation of the country’s “retreat from two to three” and “retreat from the city to the park” old city transformation policy, a large number of important metallurgical, chemical, petrochemical, steel, pesticide, and machinery manufacturing industries have emerged around the city. The soil and groundwater of the sites left behind by the relocation of polluting industries have often been contaminated. In this regard, the "Notice on Ensuring Environmental Safety in the Redevelopment and Utilization of Industrial Enterprise Sites" (Huanfa [2012] No. 140) clearly states that "strictly control the land transfer of contaminated sites. If site...

AI Technical Summary

Problems solved by technology

[0006] The technical problem solved by the present invention is that in the prior art, in the process of repairing these polluted sites, due to the characteristics and complexity of the pollutants, the control of the secondary environmental pollution is relatively difficult, and it is easy to affect the surrounding environment. The situation of the environment and residents, which brings great resistance to the restoration of contaminated sites and the healthy development of the industry, and then provides an inflatable greenhouse with an optimized structure suitable for contaminated sites
