| titleOfInvention | Soil improver manufacturing method using dredging sludge |
| abstract | The present invention relates to a method for manufacturing a soil improver using dredged sludge. When washing or classifying excavated soil or dredged soil generated at the excavation of a river, lake, or tunnel, waste, sand, gravel, etc. are classified and mixed in dredged soil. The sludge, such as sediment, is suspended in the wash water and the wash water turns into a suspension. The sludge suspended in the wash water can be recycled by coagulation and sedimentation. At this time, coagulation and precipitation of sludge in the wash water with eco-friendly natural polymer flocculant dissolved chitosan in wood vinegar, dehydrated sludge with dehydrator, and dried to dryness to 30% or less in the dry phase and then calcium sulfate or calcium phosphate, calcium sulfate and Humic acid, minerals, bentonite, zeolite is mixed with a mixture of calcium phosphate is prepared by mixing the dried sludge with a soil improver. Soil modifiers manufactured in this way used environmentally friendly natural polymer flocculant instead of synthetic polymer flocculant, and thus caused environmental pollution and adverse effect on soil in the long term. It is an economical method that eliminates urea and prevents contamination of soil and coastal areas due to landfilling or ocean dumping by dredging sludge, land dumping sludge, and soil recycling. Is to present a wayn n n n Dredge sludge, natural polymer, wood vinegar, calcium sulfate, calcium phosphate, mineral, bentonite, zeolite |
