Problems solved by technology

[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" "Serious pollution will cause secondary pollution, and nutrients will be filtered out. In addition, the recovery of soil cleaning liquid also has the problem of too much residual soil residue, which is easy to block the pipeline.

Abstract

The invention discloses a soil repair system based on micro-biological degradation. The system comprises a pollution source soil transfer unit, a physical screening unit, a stone transfer unit, a micro-biological degradation unit, a cleaning and precipitating unit, a dehydrating unit and a repaired soil source transfer unit. With adoption of a way of combining micro-biological degradation and chemical cleaning, soil is more thoroughly repaired, and secondary pollution is effectively reduced; in a recovery process of a cleaning liquid recovery module, disturbance of a water flow in a filter screen region is ensured, and the problem that the filter screen is easy to block is solved; and the cleaning liquid recovery module effectively inhibits disturbance on the bottom precipitate, so that the recovered cleaning liquid does not contain soil impurities.

Description

technical field [0001] The invention relates to the field of environmental protection machinery, in particular to a soil remediation system and method based on microbial degradation. 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" "Serious pollution will bring secondary pollution, and nutrients will also be filtered out. In addition, the recovery of soil cleaning liquid 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...
