Semi-pre-buried soil restoration sphere and using method thereof

Abstract

The invention discloses a semi-pre-buried soil restoration sphere and a using method thereof, and belongs to the technical field of soil restoration. The semi-pre-buried soil restoration sphere comprises a soil restoration sphere body and an auxiliary restoration device; the soil restoration sphere comprises a main hemisphere and an auxiliary hemisphere; the auxiliary restoration device comprisesan internally threaded cylinder, an extension tube and a tapered auxiliary rod; the lower end of the main hemisphere is fixedly connected with the internally threaded cylinder; the interior of the main hemisphere communicates with the outside through the internally threaded cylinder; a plurality of oil absorption spheres are arranged in the main hemisphere; and the internally threaded cylinder andthe auxiliary hemisphere are each provided with a plurality of evenly distributed first venting holes. Through semi-pre-burying of the soil restoration sphere in a zone where oil leakage is liable tooccur in advance, a method that prevention is a main task and treatment is an auxiliary task is adopted, oil can be adsorbed at first when oil leaks, damage caused by oil leakage to the soil is greatly reduced, the difficulty and cost of later soil restoration are greatly reduced, and environment protection and sustainable development are facilitated.

Description

technical field [0001] The invention relates to the technical field of soil restoration, and more specifically relates to a semi-pre-buried soil restoration ball and a method for using the same. Background technique [0002] Soil remediation is a technical measure to restore the normal function of polluted soil. In the soil remediation industry, there are more than one hundred existing soil remediation technologies, and there are more than ten commonly used technologies, which can be roughly divided into three methods: physical, chemical and biological. Since the 1980s, many countries in the world, especially developed countries, have formulated and carried out plans for the treatment and restoration of contaminated soil, thus forming a new soil restoration industry. [0003] Among them, the remediation of petroleum-contaminated soil is a worldwide problem. The main difficulties are: 1. The soil system is the final reservoir of petroleum pollutants, and the distribution of ...

AI Technical Summary

Problems solved by technology

[0003] Among them, the remediation of petroleum-contaminated soil is a worldwide problem. The main difficulties are: 1. The soil system is the final reservoir of petroleum pollutants, and the material distribution in the system is uneven and the controllability is poor; 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 changes 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 soil-biological system; 7. The hydrophobicity of petroleum pollutants reduces biological reactivity; 8. Affects soil There are many factors for microbial remediation, and it is difficult to study

[0004] More importantly, the existing oil-contaminated soil is rehabilitated first after pollution, which is not conducive to environmental protection, especially in the process of oil pipeline transportation on the ground, oil leakage is prone to occur at joints or complex areas. It takes a certain amount of time to discover the leak. The soil in the leaked area may have been seriously polluted by oil, and the oil may have penetrated deep into the soil. It is not only difficult to repair the seriously polluted soil, but also consumes a lot of cost. If it cannot be repaired properly , will seriously pollute the local ecological environment
