PROBLEM TO BE SOLVED: To provide a new system in backfilling by fluidization treatment soil.SOLUTION: The present application invention constructs a circulation system having a mixing device 4, a storage tank 2 for storing a treatment object liquid (w) and a compound storage part 3 for storing a compound (h), by using a continuously mixing type mixing device 4 for continuously mixing-discharging the treatment object liquid (w) and the compound (h), by receiving supply of the treatment object liquid (w) and the compound (h) including a solidification agent. The storage tank 2 and the compound storage part 3 are connected to the supply side of the mixing device 4, and the storage tank 2 is connected to the discharge side of the mixing device 4. The treatment object liquid (w) is circulated by the circulation system by repeating a step of generating a mixture (m) by mixing the treatment object liquid (w) of the storage tank 2 and the compound (h) of the compound storage part 3 by the mixing device 4 and a step of carrying the generated mixture (m) to the storage tank 2, to thereby manufacture fluidization treatment soil of enhancing the concentration of the compound (h) in the mixture (m) up to a predetermined concentration. |
