Problems solved by technology

[0002] At present, except for a small amount of fly ash produced by coal-fired facilities for construction materials, the method of centralized stacking is still adopted. A large amount of waste liquid is produced in the flue gas purification process of coal-fired facilities (such as flue gas desulfurization and denitrification purification treatment). These waste liquids are usually waste liquids containing ammonium sulfate aqueous solution, ammonium chloride aqueous solution, ammonium nitrate aqueous solution or calcium sulfate (magnesium) aqueous solution (industrial regeneration uses high energy consumption and high cost), because the main component of fly ash comes from For coal (the product of plant mineralization), the composition of fly ash is similar to that of soil or clay. If a method for producing tree planting materials and tree planting methods from fly ash and waste liquid produced in the flue gas purification process can be invented For Northwest China such as Inner Mongolia, there are a lot of sandy land and grassland soil layer structure (that is, the upper surface soil is sandy soil layer, and the lower part of the sandy soil layer is a calcareous soil layer (or calcium layer soil) with a depth of about 1 meter. Clay layer below the textured soil layer

Embodiment 1

[0049] Preparations before the implementation of the present invention:

[0050] (A) Prepare raw materials:

[0051] Prepare 860 kg of fly ash with a particle size of not more than 3.0 mm, and crush it with fresh willow branches to make 140 kg of debris with a particle size of not more than 3.0 mm. Stir 860 kg of the above-mentioned fly ash and salix twig debris with 450 kg of flue gas purification waste liquid (mainly containing ammonium salt solution of sulfurous acid and nitrous acid) in a stirring container to make a tree planting slurry A;

[0052] (B) Prospecting and surveying the tree planting area to judge the soil structure ( figure 1 ):

[0053] Measure the thickness of the ground soil layer of the embodiment (a sandy land in northern China), the thickness of the calcareous soil, estimate the depth of the grouting hole, and the insertion depth of the grouting pipe ( figure 1 , figure 2 , image 3 ), etc., determine the amount of grouting and the working parame...

Embodiment 2

[0065] Operating parameters and material preparation:

[0066] Prepare 855 kg of fly ash with a particle size not greater than 3.0 mm, and crush them with crop straw to make 145 kg of debris with a particle size not larger than 3.0 mm. Stir 855 kg of fly ash, 145 kg of crop straw debris and 450 kg of flue gas purification waste liquid (mainly containing ammonium salt solution of sulfurous acid and nitrous acid) in a stirring container to make tree planting slurry B.

[0067] Prospecting and surveying the tree-planting area (a grassland in northern China) to determine the soil structure ( figure 1 ), measure the thickness of the ground soil layer, the thickness of the calcium layer soil, estimate the depth of the grouting hole, and the insertion depth of the grouting pipe ( Figure 4 ), etc., determine the amount of grouting and the working parameters of the grouting machine, etc.; finally determine the size of each tree-planting barrel tree pit and the depth of the grouting h...

Abstract

The invention provides a tree planting slurry and a tree planting method. Fly ash and flue gas purification waste liquid are effectively utilized, the tree planting slurry prepared from the fly ash and the flue gas purification waste liquid creates soil conditions for survival of saplings, and the tree planting slurry has the advantages that the tree planting slurry is easy to prepare and grout, and the survival rate of the saplings is high. After constructed tree pits and grouting holes are filled with slurry materials, the soil texture condition for tree survival and a channel (the grouting holes) for root systems to penetrate through calcium layer soil to grow and develop downwards are established, good conditions are created for autonomous growth of the trees after many years, and the defects of a traditional tree planting method are overcome. A foundation can be laid for woodland formation of sand and diversification of grassland planting, the cost of sand prevention and sand fixation can further be reduced, and great ecological civilization and sustainable development significance are achieved.
