Soil remediation and improvement method

Abstract

The invention relates to a soil remediation and improvement method, soil remediation and improvement equipment is used, the soil remediation and improvement equipment comprises a base and a remediation device, and the remediation device is arranged on the upper surface of the base. The soil remediation and improvement method can solve the problems that when contaminated soil is remediated and improved at present, an existing soil remediation device is common in soil smashing effect, smashed soil particles are not uniform in size, large soil particles can only make full contact with remediationliquid medicine on the outer surfaces, and the interior of the large soil particles is still difficult to permeate by the remediation liquid medicine; in the prior art, remediation liquid medicine isdirectly mixed in soil to be stirred, but the remediation liquid medicine contains water, when the soil is stirred, the soil is prone to caking, the stirring effect of the remediation liquid medicineand the soil becomes poor, and then the remediation effect of the soil is reduced accordingly.

Description

technical field [0001] The invention relates to the technical field of soil remediation, in particular to a soil remediation and improvement method. Background technique [0002] Natural resources usually include mineral resources, land resources, water resources, climate resources and biological resources. It is closely related to human society; it is not only an important basis for human survival, but also a necessary condition and place for raw materials, fuel sources and production layout of social production; 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, which affects and exceeds the self-purification ability of the soil, thus causing harmful effects in hygiene and epidemiology. The impact indicates that the soil has been polluted. There are many reasons for soil pollution, such as industrial sludge, ag...

AI Technical Summary

Problems solved by technology

[0003] At present, when repairing and improving the polluted soil, there are the following problems: when the contaminated soil is repaired by spraying the repairing liquid, the polluted soil needs to be pulverized so that the repairing liquid can be fully mixed with the soil , and the existing soil remediation device has a general effect on soil crushing, the crushed soil particles are not uniform in size, there are large and small, small soil particles can be fully mixed with the repair liquid, and large soil particles can only be removed from the outer surface It is completely in contact with the repairing liquid, but its interior is still difficult to be penetrated by the repairing liquid, and the existing method of spraying the repairing liquid on the soil will also make it difficult to fully mix the repairing liquid with the soil. The liquid is directly mixed into the soil for stirring, but the repairing liquid contains water, and the soil is easy to form agglomerates when stirring the soil, which makes the mixing effect of the repairing liquid and the soil worse, and then leads to a decrease in the repairing effect of the soil
