Soil remediation method based on chemical treatment principle

Abstract

The invention relates to a soil remediation method based on a chemical treatment principle, which comprises a sliding device, a pressing device and remediation devices. The pressing device is arrangedin the sliding device, the remediation devices are uniformly arranged at the lower end of the pressing device, and the remediation devices are rotationally connected with the pressing device. According to the invention, the problems as follows are solved, namely, the existing equipment cannot perform bulking treatment on deep soil in the land when performing chemical treatment on soil, the plowing layer of the soil easily becomes shallower, the aerobic microbial activity of the land and the release of nutrients are reduced, and barren land and reduction of land quality are caused; and meanwhile, chemical agents for improving the soil can only be sprayed to the soil exposed on the surface of the air, and the chemical agents can permeate into the soil within a certain period of time, so that the remediation speed of the chemical agents to the soil is reduced, and the remediation efficiency of the soil is reduced.

Description

technical field [0001] The invention relates to the technical field of soil remediation, in particular to a soil remediation method based on a chemical treatment principle. Background technique [0002] Soil remediation is a technical measure to restore contaminated soil to normal functions. There are more than ten commonly used technologies in the soil remediation industry, which can be roughly divided into three methods: physical, chemical and biological. The technical principles of contaminated soil remediation can include: Change the form of pollutants in the soil or the way they combine with the soil, reduce their mobility and bioavailability in the environment, and reduce the concentration of harmful substances in the soil. [0003] At present, the existing chemical treatment of soil usually has the following deficiencies: 1. The existing equipment cannot fluff the soil in the depth of the land, and it is easy to cause the soil cultivation layer to become shallow, whic...

AI Technical Summary

Problems solved by technology

[0005] The present invention can solve the problem that the existing equipment cannot fluff the soil in the middle depth of the land when chemically treating the soil, and the soil plowing layer tends to become shallow, which reduces the activity of aerobic microorganisms and the release of nutrients in the land, thus causing The land is barren and the quality of the land is declining. At the same time, the soil exposed to the air surface can only be sprayed with chemicals to improve the soil. It takes a certain period of time for the chemicals to penetrate into the soil, thereby reducing the speed of the repair of the soil by the chemicals. Reduced soil remediation efficiency and other problems
