| titleOfInvention | Chelating agent recovery method in soil remediation facilities using chelating agents |
| abstract | [Problem] To provide a means for preventing a chelating agent from being taken away by a filter cake in a soil purification facility for purifying soil contaminated with a toxic metal or the like with washing water containing a chelating agent. SOLUTION: A soil remediation facility S that purifies soil contaminated with toxic metals with wash water containing a chelating agent, while filtering sludge containing fine-grained soil, and rinsing water on a filter cake for filtration. A vacuum filter for washing away the chelating agent contained in the cake and a chelating agent recovery unit 7 for recovering the chelating agent from the rinse water discharged from the vacuum filter are provided. In the chelating agent recovery method according to the present invention, rinsing water is sprayed from the rinsing water spraying device 93 on the sand in the sand container 85, while rinsing water adhering to the sand is evaporated and removed. And the sand by which the chelating agent was accumulate | stored in the sand accommodating part 85 is introduce | transduced into the classification part of the soil purification facility S, and a chelating agent is collect | recovered. In addition, the sand discharged from the classification unit is used as sand to be stored in the sand storage unit 85. [Selection] Figure 6 |
