preparation example 1

[0065] The preparation method of phosphorus modified biochar is:

[0066] A1. Crush the biochar and pass it through a 3mm sieve for later use;

[0067] A2. Potassium phosphate is dissolved in water to prepare a 10g / L potassium phosphate solution;

[0068] A3. Add 30kg potassium phosphate solution to 15kg A1 pulverized biochar, and stir for 2 hours at a speed of 80r / min to obtain a mixed solution;

[0069] A4. Filtrate the mixed solution obtained in A3, and dry the obtained filter residue at a temperature of 60° C. to prepare phosphorus-modified biochar.

preparation example 2

[0071] The preparation method of phosphorus modified biochar is:

[0072] A1. Crush the biochar and pass it through a 4mm sieve for later use;

[0073] A2. Potassium phosphate is dissolved in water to prepare a 11g / L potassium phosphate solution;

[0074] A3. Add 6kg potassium phosphate solution to 15kg A1 pulverized biochar, and stir for 2.5h at a speed of 85r / min to obtain a mixed solution;

[0075] A4. Filtrate the mixed solution obtained in A3, and dry the obtained filter residue at a temperature of 65° C. to prepare phosphorus-modified biochar.

Abstract

The invention relates to the field of mine restoration, and particularly discloses a mine ecological restoration system and an ecological restoration method. The mine ecological restoration system comprises fluffy cotton, a plant growth substrate and non-woven fabric which are sequentially arranged on the exposed surface of a mine, wherein a fixing assembly is arranged on the exposed surface of the mine, the plant growth substrate is prepared from the following raw materials of, in parts by weight, 5-15 parts of a water-retaining agent, 140-220 parts of activated sludge, 560-670 parts of fly ash, 700-900 parts of soil, 30-50 parts of straw particles and 2-8 parts of phosphorus modified charcoal, the ecological restoration method comprises the following steps that the fluffy cotton is laid on the exposed surface of the mine, the plant growth substrate is laid on the fluffy cotton, plants are planted on the plant growth substrate, then the non-woven fabric is laid on the plant growth substrate, and the plants sprout to grow into the green mine. The mine ecological restoration system can be used for ecological restoration of mines and has the advantage of enhancing the mine ecological restoration effect.

Description

technical field [0001] This application relates to the field of mine restoration, in particular to a mine ecological restoration system and an ecological restoration method. Background technique [0002] my country is rich in mineral resources. With the development of the mining industry, a large number of slope structures with unstable geological structure, low vegetation coverage and high soil pollution appear around the mine. If these slope structures cannot be treated in a timely and effective manner, On the one hand, it is easy to cause serious geological disasters such as landslides and landslides, and on the other hand, it is also easy to cause environmental pollution such as dust and groundwater pollution. [0003] The current methods of repairing mines include: surface covering method, soil filling method, and aerial planting method; surface covering means using mesh equipment to solidify the mine after mining. This method is expensive, inconvenient to manage, poor i...
