Remediation device for petroleum-contaminated saline and alkaline land soil and remediation method

Abstract

The invention discloses a remediation device for petroleum-contaminated saline and alkaline land soil and a remediation method. The remediation device comprises supporting legs, a main plate body, a combustion tank, a stepping motor, a first telescopic rod, a pulling rod, a locking rod, a combustion cylinder, an air blower and an abutting cylinder; the main plate body is of a rectangular plate structure and is provided with a plate opening, the supporting legs are welded to the lower surface of the main plate body, and universal wheels are fixed to the lower ends of the supporting legs throughthreads; and the air blower is installed on the upper surface of the main plate body through bolts, the combustion tank is fixedly welded to the surface of the portion, over the plate opening, of themain plate body, the bottom of the combustion tank is provided with a lower opening, the air blower communicates with the bottom of the combustion tank through a pipeline, the combustion tank is connected with two pipelines, the other pipeline of the combustion tank is connected with a fuel gas source, and a fuel gas valve is installed on the pipeline connected with the fuel gas. According to theremediation device for the petroleum-contaminated saline and alkaline land soil and the remediation method, petroleum components in the saline and alkaline land soil are removed in a firing mode, soil slag treatment is convenient, the introduced air combustion efficiency is high, and the remediation device is suitable for being generally popularized and used.

Description

technical field [0001] The invention belongs to the technical field of soil remediation, and in particular relates to a remediation device and method for oil-polluted saline-alkali soil. Background technique [0002] Oil pollution refers to the pollution caused by leakage and discharge of oil during oil exploitation, transportation, loading and unloading, processing and use. Oil is mainly composed of hydrocarbon compounds, a complex compound with complex composition, containing teratogenic, carcinogenic, Mutagenic substances, such as halogenated hydrocarbons, benzene series, anilines, phenanthrene, and benzopyrene, etc., soil is an important environmental basis for human survival, and soil safety is related to human food safety. Once oil enters the soil, it will Changing the nature of the soil will cause serious pollution, which will cause serious harm to human health and the ecological environment. It will take a long time to use microorganisms to purify oil-contaminated so...

[0002] Oil pollution refers to the pollution caused by leakage and discharge of oil during oil exploitation, transportation, loading and unloading, processing and use. Oil is mainly composed of hydrocarbon compounds, a complex compound with complex composition, containing teratogenic, carcinogenic, Mutagenic substances, such as halogenated hydrocarbons, benzene series, anilines, phenanthrene, and benzopyrene, etc., soil is an important environmental basis for human survival, and soil safety is related to human food safety. Once oil enters the soil, it will Changing the nature of the soil will cause serious pollution, which will cause serious harm to human health and the ecological environment. It will take a long time to use microorganisms to purify oil-contaminated soil. Phytoremediation is not suitable for oil pollution purification in saline-alkaline areas
