CONTAMINATED SOIL WASHING APPARATUS

The present invention relates to a contaminated soil washing apparatus comprising: a hopper portion for collectively putting in contaminated soil and water; a spraying portion for detaching pollutantsfrom the contaminated soil input through the hopper portion by spraying high-pressure water; a detachment portion that forms a moving path of the contaminated soil, increases a flow rate of the contaminated soil in a state where the pollutants are detached by the spraying portion, and uses bubbles generated when decompressing for continuous detachment of pollutants. 本发明涉及受污染土壤洗涤装置，其包括：料斗部，用于同投入受污染土壤和水；喷射部，通过喷射高压水来使污染物质从通过所述料斗部投入的所述受污染土壤脱离；以及脱离部，形成所述受污染土壤的移动路径，在通过所述喷射部来使污染物质脱离的状态下，增加所述受污染土壤的流速，利用当减压时产生的空泡来进行污染物质的连续脱离。
