<p><P>PROBLEM TO BE SOLVED: To provide an in-situ purification method for contaminated underground water capable of enhancing the purification performance of a permeable underground water reaction wall, maintaining the purification performance for a long time, thereby reliably purifying the water at a low cost. <P>SOLUTION: The in-situ purification method for the contaminated underground water T includes making the underground water T contaminated with an organic compound pass through the permeable underground water purification wall 2 filled with a filling material 2b including a clarification material 2a, thereby purifying the contaminated underground water T with the clarification material 2a. In the purification method, by constructing the permeable underground water purification wall 2 filled with the filling material 2b including a biomaterial 2c in addition to the clarification material 2a and by making the contaminated underground water T pass through the permeable underground water purification wall 2, the contaminated underground water T is purified with the clarification material 2a, and also the contaminated under ground water T is purified by decomposing the organic compound by the microorganism in the biomaterial 2b. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
