Circulation spraying system for farmland polluted soil repairing treatment

Abstract

The invention relates to the technical field of soil treatment devices and in particular to a circulation spraying system for farmland polluted soil repairing treatment. The system comprises a running vehicle, soil crushing mechanisms and a spraying mechanism, wherein the running vehicle comprises a control mechanism, a working table and running wheels; the working table is of a rectangular plate-shaped structure; the control mechanism is arranged at a side part of the working table; the running wheels are mounted at bottoms of the working table and the control mechanism; a plurality of lifting mechanisms are arranged on one side close to the control mechanism, of the working table; output ends of the lifting mechanisms extend downwards vertically below the working table; the soil crushing mechanisms are fixedly mounted at output ends of the lifting mechanisms; the spraying mechanism comprises a mixing tank, a stirring mechanism and a plurality of raw material storage tanks; the stirring mechanism is arranged on one side close to the lifting mechanisms, of the mixing tank; and the raw material storage tanks are all arranged at a side part of the mixing tank. By adopting the system, the soil treatment and repairing efficiency can be improved, and a good treatment effect can be achieved.

Description

technical field [0001] The invention relates to the technical field of soil treatment devices, in particular to a circulating spray washing system for remediation and treatment of farmland polluted soil. Background technique [0002] 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. [0003] Chemical leaching, with the help of chemical / biochemical solvents that can promote the dissolution or migration of pollutants in the soil environment, the eluent is injecte...

AI Technical Summary

Problems solved by technology

[0003] Chemical leaching, with the help of chemical / biochemical solvents that can promote the dissolution or migration of pollutants in the soil environment, the eluent is injected into the polluted soil layer under the action of gravity or by hydraulic head pressure. The current soil remediation treatment prevents the inability to The soil is fully treated, and the efficiency is low
