Title:
SOLID WASTE-BASED POROUS MATERIAL, PREPARATION METHOD THEREFOR AND METHOD FOR ECOLOGICAL RESTORATION OF COAL GANGUE MOUNTAINS
Document Type and Number:
WIPO Patent Application WO/2022/160922
Kind Code:
A1
Abstract:
A solid waste-based porous material, a preparation method therefor and a method for the ecological restoration of coal gangue mountains. A coal-based solid waste restoration material is mixed with a mycorrhizal solid bacteria agent to restore coal gangue mountains; the coal-based solid waste restoration material is prepared by mixing a coal-based solid waste porous material, a low-rank coal and waste organic matter with a microbial quick-decomposing agent and then performing aerobic fermentation and precipitation; the solid mycorrhizal bacteria loaded on the solid waste-based porous material can maintain activity for a long time, which is more convenient for storage than a liquid bacterial agent; the porous material provides a safe and suitable growth space for mycorrhizal mycelium; substances secreted by mycorrhizal bacteria can affect the performance of the porous material and enhance the interaction between the porous material and soil particles. Thus, the present invention has the potential to promote the formation of soil aggregates that use porous material as the core. The structure-activity relationship between a coal-based solid waste porous carrier material and the activity of mycorrhizal bacteria promotes the growth of mycorrhizal bacteria and the rooting of plants, and the ecological restoration of an ecologically fragile area of a coal power base is achieved.
