Soil washing restoration system based on reduction concentration design concept and method thereof

The invention discloses a soil washing restoration system based on a reduction concentration design concept and a method thereof. The washing restoration system comprises the following four module units which are sequentially connected with one another: a feeding and screening unit, an ore washing unit, a sludge dewatering unit and a tail-end sewage treatment recycling unit. The pollutants on the surface of coarse particles are eluted, transferred and concentrated into the filter-pressed mud cake by virtue of washing, so that pollutant-containing fine particles in contaminated soil can be effectively separated from crude particles such as gravel and grit. The repaired and discharged clean gravel and grit can be directly recycled to serve as building material. According to the system, purified water serves as a washing solution, so that secondary pollution caused by addition of a chemical washing agent is avoided, and the washing solution is treated by a tail-end sewage treatment system so as to be recycled. The reduction of remediation of contaminated soil is realized, the comprehensive repair cost is greatly reduced, the washed and discharged materials can be recycled, the contaminated soil is repaired, and a novel profit point is created.
