A soil remediation system and method

Abstract

The invention discloses a soil remediation system and method. The soil remediation system comprises a polluted soil source conveying unit, a heating and volatilizing unit, a cleaning and sediment unit, a dehydration unit, a faeces conveying unit, a fermentation unit, a soil-fertilizer mixing unit and a remedied soil source conveying unit. According to the soil remediation system and method, the problem that remedied soil is heavily sandy and lack of nutrients are solved through a fermented faeces and treated soil mixing method; disturbance of water flow in a filter screen area is guaranteed in the recovery process of a cleaning fluid recovery module, and the problem that filter screens are likely to be blocked is solved; disturbance on bottom sediments is effectively suppressed through the cleaning fluid recovery module, so that recycled cleaning fluid does not contain soil and impurities.

Description

technical field [0001] The invention relates to the field of environmental protection machinery, in particular to a soil restoration system and method. Background technique [0002] The overall situation of China's soil environment is not optimistic. The national soil pollution rate is as high as 16.1%. While the soil environment problems of industrial and mining abandoned land are prominent, the soil environment quality of cultivated land is even more worrying. However, existing soil remediation equipment has repaired soil "sand" "The pollution is serious, and the nutrients are also filtered out. In addition, the recovery of the soil cleaning solution also has the problem of too much residual soil residue, which is easy to block the pipeline. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a soil remediation system and method, which can remediate polluted soil sources. [...

[0002] The overall situation of China's soil environment is not optimistic. The national soil pollution rate is as high as 16.1%. While the soil environment problems of industrial and mining wasteland are prominent, the soil environment quality of cultivated land is even more worrying. However, existing soil remediation equipment has repaired soil "sand" "The pollution is serious, and the nutrients are also filtered out. In addition, the recovery of the soil cleaning solution also has the problem of too much residual soil residue, which is easy to block the pipeline.
