Disclosed is a purifier for purifying soil contaminated with heavy metals. The contaminated soil purification device is disposed in the soil and configured to introduce microbial fluid or electrolyte solution into the body. First, in the microbial treatment step, the microbial fluid is introduced into the body to treat the contaminated soil through microbial reaction. After the electrokinetic treatment step, the electrolyte solution is introduced into the body again to purify the contaminated soil through the electrode reaction. |
