Contaminated soil waste separation treatment system and method

Abstract

The invention relates to a contaminated soil waste separation treatment system and method. The system comprises a workbench, a fixing device and a separation device, wherein the fixing device is arranged at the top of the workbench, and the separation device is arranged on the fixing device. By means of the workbench, the fixing device and the separation device, when soil remediation is conducted on saline-alkali soil, firstly, excavated soil waste is placed in the fixing device, at the moment, through the cooperation of the separation device, large particles in soil are rapidly sorted; when soil remediation is conducted on the arid land, after the excavated soil waste is placed in the fixing device, the separation device is used for crushing caked soil and then separating the soil and the large particles, so that the porosity of the remediated soil is guaranteed, and the remediated soil can be directly returned to the field for use.

Description

technical field [0001] The invention relates to the technical field of separation and treatment of soil waste, in particular to a system and method for separation and treatment of polluted soil waste. Background technique [0002] When there are too many various pollutants contained in the soil, which exceeds the self-purification capacity of the soil and produces harmful effects, it indicates that the soil is polluted. There are many reasons for soil pollution, such as industrial sludge, garbage for agriculture, sewage irrigation, The sedimentation of pollutants in the atmosphere, the extensive use of heavy metal-containing mineral fertilizers and pesticides, etc., make the soil unusable, so it needs to be repaired. When repairing the soil, the polluted soil should be excavated first, and then the large particles of waste should be excavated. Sorting is carried out. After sorting, chemicals are added to the soil and mixed evenly with a mixer. Finally, the repaired soil is r...

Problems solved by technology

[0004] (2) When soil remediation is carried out on arid land, it is necessary to break the soil agglomerates first, and then separate the large particles in the soil from the soil, so as to obtain loose soil. The traditional soil remediation method is through artificial Use tools to loosen the soil and then separate the large particles. In this way, the degree of loosening of the soil cannot be guaranteed, and part of the soil after sorting cannot be returned to the field.
