Abstract

The invention provides a quarry muck spray-seeding medium and a spray-seeding method thereof. The spray-seeding medium comprises a medium layer and a seed layer, wherein the medium layer is located onthe bottom layer, and the seed layer is located on the upper layer of the medium layer. The medium layer is mainly prepared from, by mass, 50-60% of muck A, 5-10% of biochar, 10-15% of straw, 5-13% of cement, 1-3% of potassium sulphate, 1-2% of acrylamide and 10-15% of biogas slurry; the seed layer is mainly prepared from, by mass, 30-40% of muck B, 20-35% of sludge, 30-35% of biogas residues, 1-2% of starch grafted sodium polyacrylate, 1-2% of polyacrylamide and 1-2% of plant seeds. According to the spray-seeding medium, the quarry muck is used as the main raw material to replace soil used in an existing soil replacement spray-seeding technology, and the quarry muck spray-seeding medium has certain social, biological and economic values.

Description

technical field [0001] The invention relates to the field of solid waste utilization and environmental protection, in particular to a quarry muck spraying matrix and a spraying preparation method thereof. Background technique [0002] Quarry slag refers to the slag produced in the construction process of quarry blasting excavation and manual excavation. The main way to dispose of muck in my country is to choose low-lying land and wasteland for open-air stacking, which not only occupies a large amount of land, aggravates the contradiction between more people and less land, but also pollutes soil, water and atmosphere, and affects the urban landscape. From the above, it can be seen that the direct use value of quarry dregs is low, which is a huge waste of resources. The accumulation of muck has a huge impact on the mining landscape, land resources, water environment, biodiversity, etc., and even endangers the survival and health of human beings, and affects the sustainable de...
