Abstract

The invention discloses a petroleum soil pollution remediation process for promoting crude oil degradation, and relates to the technical field of soil remediation. According to the petroleum type soil pollution remediation process, sampling detection is conducted after region division, soil of different regions and different depths can be drilled at the same time for petroleum hydrocarbon content detection, application of a remediation agent and degradation bacterium liquid is facilitated adaptively, and the situation that the dosage of the remediation agent and the dosage of the degradation bacterium liquid are unreasonable is avoided; volatile gas and oil-water mixtures in the soil can be adsorbed, filtered and purified through negative pressure extraction and purification; in the degrading bacterium liquid degrading and soil repairing agent repairing process, the adding amount of degrading bacterium liquid and a soil repairing agent is adjusted according to the petroleum hydrocarbon content of soil at different depths in different areas. According to the petroleum soil pollution remediation process, targeted remediation treatment of soil in different areas and different depths can be achieved, the effect of effectively degrading petroleum hydrocarbon in crude oil for a long time is achieved, and the remediation cost is saved.

Description

technical field [0001] The invention relates to the technical field of soil remediation, in particular to a petroleum-based soil pollution remediation process that promotes degradation of crude oil. Background technique [0002] The remediation of petroleum-contaminated soil is a worldwide problem. The main difficulties are: 1. The soil system, as the final reservoir of petroleum pollutants, has uneven distribution of substances in the system and poor controllability; 2. The composition of petroleum products is complex, It is not conducive to the bioremediation of a single strain; 3. The biodegradability of petroleum products varies with the type and size of its components; 4. The heavy content is high, the bioremediation speed is slow, and the toxicity is strong after remediation; 5. 1. Pollutants form dynamic phase equilibrium and chemical balance locally in the system; 6. Toxic and harmful pollutants change the normal life behavior of the soil-biological system; 7. The hy...
