Fertility-increasing type soil remediation system and method

Abstract

The invention discloses a fertility-increasing type soil remediation system which comprises a soil source conveying unit, a micro-biological degradation preprocessing unit, a micro-biological degradation unit, a sediment cleaning unit, a dewatering unit, an excrement conveying unit, a sterilizing and deodorizing unit, a soil fertilizer mixing unit and a remediated soil source conveying unit. According to the invention, the processed excrement is mixed with the processed soil, so as to solve the problems of serious sanding and insufficient nutrient of the soil; a recycling process of a cleaning liquid recycling module can guarantee the water flow disturbance in a filter screen area, so that the problem of easiness in blocking the filter screen can be solved; and the cleaning liquid recycling module can effectively restrain the disturbance of bottom sediment, so that the recycled cleaning liquid contains no soil impurity.

Description

technical field [0001] The invention relates to the field of environmental protection machinery, in particular to a fertilizer-enhancing 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 fertilizer-enhancing soil remediation system and method, which...

[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.
