[0002] Soil remediation is a technical measure to restore the normal function of polluted soil. Currently, the commonly used soil remediation methods include physical, chemical and microbial methods. Although physical and chemical methods have direct effects and quick results, their sustainability is poor. Moreover, if the methods or dosages are used improperly, not only the remediation effect cannot be achieved, but also new pollution will be brought. The composite method is comprehensive, integrated, and has strong sustainability. It can also provide nutrients during remediation to avoid soil infertility and will not cause any adverse effects. Among them, the microbial method has become the research direction of comprehensive soil remediation due to its mild nature, strong affinity with soil, and thorough action. Its combined use with other methods

[0003] In the prior art, such as 2015108103852, it discloses a biological organic type remediation agent for soil pollution and its use and preparation method. The specific use method is to evenly spread the biological organic type remediation agent for soil pollution on the soil surface and then plow it. The biological organic type remediation agent for soil pollution is used at 2000 - 3000 kg / mu for repairing heavy metal pollution, 700 - 1300 kg / mu for repairing saline-alkali soil, 500 - 1000 kg / mu for degrading chemical fertilizer and pesticide pollution, and 400 - 800 kg / mu for soil improvement.

[0004] For another example, the patent number is 2021226309958, which discloses a microbial remediation device for soil pollution treatment.

Structurally, an oxygenating agent is provided in the plug body 207. When the sprayed water source enters the plug body 207, the oxygenating agent will generate oxygen, thereby performing oxygen filling work inside and providing a certain aerobic environment for the growth of microorganisms, or using the oxygen in the residual soil during the process of turning over the covering soil for activities.

[0045] At the same time, during implementation, both ends of the upper sleeve 202 and the lower sleeve 203 are provided with gradually narrowing ends, which are convenient for inserting the device into the hole.
