Problems solved by technology

At present, the method of ecological restoration in mining areas is mainly based on foreign soil landfill, but land resources are very scarce, and it is impossible to increase a large area of ​​land for soil improvement of mine wasteland
At present, the soil improvement substrates in mining areas are mostly chemical reagents (neutralizing acid and alkali) and chemical fertilizers (chemical organic fertilizers, nitrogen, phosphorus and potassium fertilizers, etc.), which have the problems of high cost, slow effect and complicated preparation methods.

preparation example Construction

[0027] The present invention also provides a preparation method of the environmental ecological restoration matrix, comprising the following steps: 1) mixing eucalyptus bark, papermaking sludge and domestic sludge to obtain a sludge mixture; 2) mixing the sludge mixture with Neem, Tea bran powder, potassium feldspar tailings powder, phosphate ore tailings powder are mixed with 60% to 70% of the total amount of bioactive bacteria to obtain a compost mixture; Aerobic composting to obtain compost products; the temperature of the aerobic composting is 60-70°C; the time of the aerobic composting is 28-30d; the aerobic composting process is turned; 4) Dry the compost product and mix it with silicon micropowder and grass seeds to obtain an environmental ecological restoration matrix.

[0028] In the present invention, eucalyptus bark, paper sludge and domestic sludge are mixed to obtain a sludge mixture. In the present invention, the eucalyptus bark is dried so that the water conten...

Embodiment 1

[0036] An environmental ecological restoration matrix, calculated on a dry basis, includes the following components in mass percentages: 28% of papermaking sludge, 26% of domestic sludge, 18% of eucalyptus bark, 2% of neem seeds, 4.5% of tea bran powder, Potassium feldspar tailings powder 6%, phosphate rock tailings powder 3%, bioactive bacteria agent 0.8%, silicon micropowder 12%, grass seed 0.3%.

[0037] Preparation:

[0038] A, first eucalyptus bark is air-dried to water content and is 10%, cut into 1cm long; Phosphate rock, potassium feldspar tailings, through mechanical pulverization, obtain fine powder below 60 orders; %, crushed to below 80 mesh for later use.

[0039] B, take the chemical pulp papermaking sludge and domestic sludge with a water content of 75-80%, mix them with the eucalyptus bark fragments prepared in step A, and make the water content of the mixture be controlled at 55% to 60%, and then add the preparation made in step A The obtained phosphorus, po...

Abstract

The invention provides an environmental ecological restoration substrate, and belongs to the technical field of ecological restoration. The environmental ecological restoration substrate is prepared from, by mass based on dry basis, paper sludge 22-30%, domestic sludge 20-30%, eucalyptus bark 18-25%, fructus meliae azedarach 1.5-2%, tea bran powder 3.5-5%, potash feldspar tailings powder 4-6%, phosphate ore tailings powder 3-5%, biologically active microbial agent 0.7-1.0%, silica powder 8-12% and grass seed 0.3-0.5%. The environmental ecological restoration substrate utilizes wastes or by-products in industry, agriculture and mining such as the paper sludge, the domestic sludge, the eucalyptus bark, the potash feldspar tailings powder, the phosphate ore tailings powder, the silica powderand the like, the production cost is low, and the comprehensive utilization of waste resources is achieved; the environmental ecological restoration substrate has a wide application range, simple operation, quick effect and environmental safety, and the ecological restoration problem of the damaged environment can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of ecological restoration, and in particular relates to an environmental ecological restoration matrix and a preparation method and application thereof. Background technique [0002] Geology of the mining area During the mining process, the surface of the ground has been stripped of vegetation, leaving mining pits, waste rocks, and tailings piled up in large quantities, leaving piles of gangue, which have hidden dangers of mountain collapse, mudslides, and landslides; on the other hand, the underground remains After entering a large-scale empty mining area, it is prone to subsidence for a long time. In the long run, the environment of the mining area will be irreversible. Not only will the landscape be damaged, but the long-term exposed rocks will cause soil erosion, desertification and weathering of the mountain, which will bring hidden dangers to the production and life of the residents around the mining a...
