Abstract

The invention discloses a method and an experimental device for repairing petroleum hydrocarbon pollution in a heterogeneous aquifer. The steps of the method include: preparing microbial flora, and the metabolites of the microbial flora include extracellular polysaccharides and biosurfactants; Injection of microbial flora into petroleum hydrocarbon-contaminated heterogeneous aquifers; in situ cultivation of microbial flora. In one embodiment of the present invention, in situ cultivation of microbial flora can effectively increase the sweeping range of the remediation agent, thereby increasing the efficiency of remediation of petroleum hydrocarbon pollution in heterogeneous aquifers.

Description

technical field [0001] The invention relates to the technical field of remediating pollution of aquifers, and more specifically, to a method and an experimental device for remediating petroleum hydrocarbon pollution of heterogeneous aquifers. Background technique [0002] The rupture of oil pipelines and the leakage of oil storage tanks at gas stations will cause a large amount of petroleum hydrocarbon pollutants to enter the underground aquifer, which exists alone in the oil phase because it is insoluble in water. Petroleum hydrocarbon pollutants accumulate in aquifers and are difficult to remove through natural attenuation, thus becoming a long-term pollution source and seriously threatening human health and the ecological environment. [0003] The structure of the natural underground aquifer is complex, showing a certain spatial structure and variability. The aquifer may partially contain low-permeability clay and high-permeability coarse sand and gravel layers, which mak...
