Document Type and Number:
WIPO Patent Application WO/2021/164098
Kind Code:
A1
Abstract:
A system for treating medium and low concentration petroleum hydrocarbon contaminated soil, comprising a pile body foundation anti-seepage system. Petroleum hydrocarbon contaminated soil is piled above the pile body foundation anti-seepage system to form a pile body; and a pile body inflation system, a pile body liquid filling system, a soil monitoring system, a waste gas collection system and a leachate collection and treatment system are laid in the pile body. Meanwhile, a rainproof covering system is laid above the pile body, plants are transplanted on the surface of the pile body, earthworms are added, and thus an artificial ecosystem integrating microorganisms, animals and plants is formed to treat the medium and low concentration petroleum hydrocarbon contaminated soil. A method for treating medium and low concentration petroleum hydrocarbon polluted soil, comprising the steps of: performing soil early-stage test, performing soil pretreatment, building a soil pile body, building a biological pile body and performing biological pile body daily monitoring and maintenance treatment. The system and the method improve the degradation efficiency of biological pile body pollutants and realize remediation of medium and low concentration petroleum hydrocarbon contaminated soil.
