<p><P>PROBLEM TO BE SOLVED: To provide a method for cleaning polluted soil and ground water constituted so that anaerobic microorganisms living in soil or ground water are stably propagated over a long period of time (always) to be activated not only to optimize the original position cleaning treatment or control of pollution but also to simplify each cleaning treatment equipment or facilities. <P>SOLUTION: A nutrient tank, which stores a nutrient based on a 6 or above C straight chain saturated monocarboxylic acid, a vertical injection well and horizontal injection well, both of which inject the nutrient in soil and ground water of a polluted part or the diffusion region thereof by an injection machine, and a vertical observation well for monitoring a cleaning state by the injection of the nutrient are used to propagate and activate anaerobic microorganisms by the injected nutrient to decompose volatile organic compounds of the polluted part and the diffusion region thereof caused by the volatile organic compounds. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
