Description

A soil repair device

technical field

The invention relates to the field of soil restoration, in particular to a soil restoration device.

Background technique

The soil is originally a natural shelter and purification treatment place for various wastes. The soil accepts pollutants, which does not mean that the soil is polluted. Only when the soil contains too many pollutants, it affects and exceeds the self-purification ability of the soil. , thus producing harmful hygienic and epidemiological effects, which indicate that the soil has been polluted. There are many reasons for soil pollution, such as industrial sludge, agricultural garbage, sewage irrigation, pollutant deposition in the atmosphere, heavy use of mineral fertilizers and pesticides containing heavy metals, and so on.

Soil remediation refers to the use of physical, chemical and biological methods to transfer, absorb, degrade and transform pollutants in the soil, reducing its concentration to an acceptable level, or converting toxic and harmful pollutants into harmless substances. Fundamentally speaking, the technical principles of contaminated soil remediation can include: (1) Change the form of pollutants in the soil or the way they combine with the soil to reduce their mobility and bioavailability in the environment; ( 2) Reduce the concentration of harmful substances in the soil.

The way of chemical repair is to mix the soil repair agent with the soil. The chemical repair method is convenient to implement and the repair cycle is short. The traditional chemical repair method cannot mix the chemical repair agent with the soil efficiently. Direct spraying or throwing Soil remediation agents do not do a good job of getting the soil in contact with the remediation agent.
