| titleOfInvention | Soil purification system |
| abstract | [PROBLEMS] To provide a simple and low-cost soil remediation system capable of classifying gravel, sand and fine particles while washing soil with washing water, while reducing harmful metals adsorbed on the fine particles. To do. A soil purification system S includes soil classification units 1 to 8, an iron removal device 12 as a pretreatment unit, and a chelate cleaning device 14 as a posttreatment unit. The soil classification units 1 to 8 crush the gravel and sand in the soil with the mill breaker 3 while washing the soil with washing water, and then use the trummel 4, cyclone 5 and thickener 8 to remove the gravel, sand and fine particles. And classify. The iron removing device 12 uses magnetic balls to adsorb and remove iron-based fine particles from the sludge containing fine particles separated by thickener 8 and washing water by magnetic force. Reduce the rate. The chelate cleaning device 14 removes harmful metals and the like from sludge (fine particles) using a chelate cleaning liquid. [Selection] Figure 1 |
