METHOD FOR RECOVERING PERFORMANCE OF PERMEABLE GROUND WATER PURIFYING BODY

机译:恢复渗透性地下水净化主体性能的方法

摘要

PROBLEM TO BE SOLVED: To provide a method for recovering the performance of a permeable ground water purifying body, which can easily recover the function of the permeable ground water purifying body at a low cost.;SOLUTION: The method for recovering the performance of a permeable ground water purifying body recovers, in situ, the purifying function of a permeable ground water purifying wall 1 including a metal reducing agent as a reaction material. In the method, a reducing agent solution 6, which is a solution of L-ascorbic acid in a concentration range of ≥0.1 mol/L and ≤0.5 mol/L, is supplied to the permeable ground water purifying wall 1 so as to remove a corrosion film formed around the metal reducing agent.;COPYRIGHT: (C)2012,JPO&INPIT
