Embodiment 1

[0034] Such as Figure 2-4As shown, the present embodiment provides a petroleum soil sampling device, including a plurality of support columns 20 arranged on both sides of the gridded soil area 10, and the support columns 20 on both sides are connected with A plurality of installation plates 21 above the area 10, a plurality of installation plates 21 are provided with an installation cylinder 22 corresponding to each gridded soil area 10, a cavity 23 is provided in the installation cylinder 22, and a cavity 23 is provided above the installation cylinder 22. The vertical limiting plate 24, the limiting plate 24 and the cavity 23 are provided with a sampling mechanism that can vertically extend into the gridded soil area 10, and the bottom of the support column 20 is provided with a sampling mechanism that extends into the gridded soil area 10. The counterweight pile 25.

[0035] Sampling mechanism comprises drilling rod 11, and the top of drilling rod 11 is provided with the s...

Embodiment 2

[0039] Such as Figure 5-6 As shown, this embodiment provides a petroleum soil pollution remediation system that promotes crude oil degradation, including a plurality of pipe piles 30 that are arranged in the limiting plate 24 and the cavity 23 and extend vertically into the gridded soil area 10 , the bottom of the pipe pile 30 extends to the bottom of the gridded soil area 10, the top of the pipe pile 30 extends out of the limit plate 24, and the pipe pile 30 is located in the gridded soil area 10 and communicates with a plurality of horizontally extending extraction A solenoid valve 32 is provided at the junction of the liquid feeding pipe 31 , the extraction liquid feeding pipe 31 and the pipe pile 30 , and a plurality of vacuum liquid feeding ports 33 are provided on the path of the extraction liquid feeding pipe 31 .

Embodiment 3

[0045] Such as Figure 1-6 As shown, the present embodiment provides a petroleum-based soil pollution remediation process that promotes degradation of crude oil, comprising the following steps:

[0046] Regional division: evenly divide the contaminated petroleum soil into multiple regions to form multiple gridded soil areas 10; the length and width of each gridded soil area 10 are 3-5m, and the depth is 0.6-1.5m .

[0047] Sampling detection: through the petroleum soil sampling device, the soil corresponding to different regions and different depths is taken out from multiple sampling holes 15, and the petroleum hydrocarbon content is detected by the soil petroleum hydrocarbon detector. Specifically, the driving motor drives the driving gear 26 to rotate, the driving gear 26 drives the drill rod 11 to rotate and lift, and the driven gear 27 assists in rotating support to keep the drill rod 11 stable to rotate and lift. A plurality of sampling holes 15 are used to take out so...

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...
