Surface soil prosthetic devices

Technical Field

The invention belongs to the technical field of soil remediation, relates to a remediation device, and particularly relates to a surface soil remediation device.

Background

Soil contamination can be caused by many factors, again the main being due to the presence of non-naturally occurring substances in the natural soil environment, such as leaks in underground storage tanks, excessive use of pesticides, infiltration of contaminated surface water into underground formations, oil and fuel discharge, waste leaching from landfills or direct discharge of industrial waste to the soil, etc. The organic pollution of the soil mainly refers to the pollution of chemical pesticides, which can change the composition and physicochemical properties of the soil, then destroy the normal composition of the soil, and finally cause harm to the health of human bodies through the processes of plant absorption, food chain accumulation and the like. Soil remediation is a technical measure to restore normal function to contaminated soil. In the soil remediation industry, the existing soil remediation technologies reach over one hundred, and the soil remediation is to transfer, absorb, degrade and transform pollutants in soil by physical, chemical and biological methods so as to reduce the concentration of the pollutants to an acceptable level and transform toxic and harmful pollutants into harmless substances. In the past, soil was manually turned over and soil conditioners were applied, which was slow, and soil remediation devices that excavated the soil and applied remediation agents became inoculated.

Through retrieval, as disclosed in chinese patent literature, a soil remediation agent application apparatus [ application number: CN 201821369162.2; publication No.: CN209156715U ].
