Repairing system for preventing soil gas invasion

Abstract

The invention relates to a repairing system for preventing soil gas invasion. The repairing system comprises a pressure monitoring system, a pollutant concentration monitoring system, a control center and a flow monitoring system, wherein the pressure monitoring system is used for detecting the pressure difference between the position under the stratum and the indoor space in real time and transmitting the detected pressure difference to the control center; the pollutant concentration monitoring system is used for detecting the concentration of pollutants in soil gas under the stratum in real time and transmitting the detected concentration information to the control center; the control center judges the possibility of health risks caused by soil gas invasion according to the received pressure information and the concentration information of the pollutants and starts a soil gas exhaust system if the health risks exceed a threshold; the flow monitoring system is used for providing an operation effect of the soil gas exhaust system and feeding back flow data to the control center; and the control center controls the operation state of the soil gas exhaust system according to the feedback information. The repairing system is low in cost, can effectively prevent soil gas invasion and can be widely applied in the environmental modification field.

Description

technical field [0001] The invention relates to an environment restoration system, in particular to a restoration system for preventing soil gas intrusion in polluted sites. Background technique [0002] Various industrial activities, including chemical production, machinery manufacturing, metal smelting, etc., cause a large amount of pollutants to be diffused into various environmental media. Among them, the pollution of soil by human activities is the most difficult problem to solve because of its concealment and long-term nature. Western countries have been engaged in the restoration of contaminated sites since the 1970s, and a large amount of funds have been invested in large and small restoration projects. In the United States, the annual restoration funds are between 10 billion and 20 billion U.S. dollars; but even so, an estimate by the US Environmental Protection Agency in 2004 pointed out that there are still nearly 300,000 polluted sites in the United States that ...
