Description

[0002] In recent years, with the development of land, the soil problem of abandoned land of industry and mining is more and more prominent, and the quality of cultivated land soil environment is worrying. In the face of the serious situation of soil pollution, soil remediation technology can restore the normal function of the damaged soil. Soil remediation technology can be mainly divided into physical, chemical and biological three kinds. The commonly used method is to spray bacteria liquid to the soil.

[0003] At present, when spraying bacteria liquid, the bacteria liquid is usually sprayed to the surface of the soil by artificial use of the spray head. The bacteria liquid sprayed to the surface of the soil is difficult to penetrate into the deep soil. Most of the bacteria liquid is exposed on the surface of the soil, which causes the microorganisms in the bacteria liquid to be unable to grow and reproduce quickly, resulting in low soil remediation efficiency. In addition, there may be hardened soil blocks in the soil. A part of the bacteria liquid may be directly sprayed on the soil blocks. The soil blocks will block the flow of the bacteria liquid, so that the bacteria liquid is difficult to flow uniformly to the inside of the soil, resulting in poor soil remediation effect. SUMMARY
