Soil remediation device and method

Abstract

The invention discloses a soil remediation device and method. The device comprises a volatile gas capture device, a gas extraction device and a waste gas treatment device. The volatile gas capture device is composed of a plurality of transverse remediation pipes. The method comprises the following steps: investigating the pollution condition; forming a remediation protection layer; digging a vertically downward longitudinal side well on the inner side of a gas station site far away from the traffic road; conducting transverse well point layout, and conducting transverse well building on a pollution source area of the gas station site with the side well as the starting point of well drilling; and starting a heating resistance rod and the gas extraction device, and collecting volatile organic pollutants in the transverse remediation pipes. By means of the method, under the premise that normal use of the site ground gas station is guaranteed, remediation of soil under the ground is achieved, the heat conduction performance of the soil is enhanced, underground water is rapidly remediated, diffusion of pollutants around is cut off, and then the overall remediation effect of the gas station is improved.

Description

Technical field [0001] The invention relates to the technical field of restoration engineering, in particular to a soil restoration device and method. Background technique [0002] With the implementation of national environmental protection policies, almost all large and medium-sized cities across the country are facing the closure and relocation of a large number of companies in heavily polluting industries, resulting in a large number of leftover and abandoned sites in the city. A considerable number of sites will be developed directly without restoration. , Will cause a lot of environmental problems. According to the national soil pollution survey data released by the Ministry of Environmental Protection, the overall soil environment in the country is not optimistic. Soil pollution is heavy in some areas, the soil environmental quality of arable land is worrying, the soil environmental problems of industrial and mining wastelands are prominent, and a large number of gas stati...

Problems solved by technology

This method intends to achieve the purpose of repairing soil and groundwater with multiple methods, but this method builds a repair device from the ground based on the premise that the gas station is abandoned, or in other words, the repair of the gas station affects the normal operation of the gas station. Obviously, this One point is inconsistent with the actual needs
