CONTAMINATED SOIL TREATMENT SYSTEM

摘要

A contaminated soil treatment system (10) is configured to contain a municipal water tank (14), a hopper (16) into which contaminated soil (20) is injected, a separating device (40), a segregating device (60), a circulating device (70), a flocculation tank (92), and a plurality of pipes disposed among these. The separating device (40) comprises a transporting ejector (48) that injects gas-accompanied jetted water (44), and a separating unit (50) that separates sandy material (24) from clay material (22) in the contaminated soil (20) by colliding the gas-accompanied jetted water (44) with the contaminated soil (20) that is delivered to a distal end of the transporting ejector (48). The circulating device (70) circulates circulation water (28) in which the clay material (22) is mixed using the negative pressure of the gas-accompanied jetted water (86) injected by an intake ejector (88), and the contaminated material adhering to the clay material (22) is reabsorbed into an adsorbent (74).
