Production method of asbestos tailing carbonized nutrient soil

Abstract

The invention discloses a production method of asbestos tailing carbonized nutrient soil. The production method is characterized by comprising the following steps: firstly stirring ingredients of asbestos tailing carbonized soil and extruding the ingredients of asbestos tailing carbonized soil to form flaky grains through pressing, performing carbonizing treatment on the asbestos tailing carbonized soil, then palletizing and sterilizing the ingredients of asbestos tailing carbonized soil, and packaging the asbestos tailing carbonized nutrient soil. The asbestos tailing carbonized nutrient soil consists of asbestos tailings, activated clay waste residue, peat, attapulgite clay, bentonite, zeolite, waste, vermiculite, diammonium phosphate, perlite, super absorbent resin and ferrous sulfate. A great quantity of nitrogen, phosphorus, potassium, organic matters and trace elements are contained in the asbestos tailing carbonized nutrient soil, the asbestos tailing carbonized nutrient soil is high-quality nutrient soil which is complete in nutrition ingredients, high in fertilizer efficiency, free of toxicity, bacteria, harm or odor and good in water retention capacity, and the asbestos tailing carbonized nutrient soil is suitable for planting flowers and nursery stocks; and the production method of the asbestos tailing carbonized nutrient soil is suitable for producing carbonized nutrient soil and nutrient medium.

Description

technical field [0001] The invention relates to nutrient soil, in particular to a production method of asbestos tailings carbonized nutrient soil. Background technique [0002] Most of the nutrient soil raw materials used by existing flower seedlings are mixed with materials such as mountain mud, garden soil, pond mud, peat soil, river sand, plant ash, wood chips, crop straw, fungus cultivation waste and humus. The soil has not undergone reasonable ingredients, disinfection and sterilization, poor water and fertilizer retention, poor air permeability, and easy compaction. The mineral nutrients in the nutrient soil are difficult to be absorbed by flower seedlings, and flower seedlings are also affected by viruses and bacteria in the soil. and newly sprouted weeds are not conducive to the normal growth and development of flower seedlings. [0003] Both phosphorus and potassium are essential nutrients for the growth of flower seedlings. Although the nutrient soil contains a ce...

Problems solved by technology

[0002] Most of the nutrient soil raw materials used by existing flower seedlings are mixed with materials such as mountain mud, garden soil, pond mud, peat soil, river sand, plant ash, wood chips, crop straw, fungus cultivation waste and humus. The soil has not undergone reasonable ingredients, disinfection and sterilization, poor water and fertilizer retention, poor air permeability, and easy compaction. The mineral nutrients in the nutrient soil are difficult to be absorbed by flower seedlings, and flower seedlings are also affected by viruses and bacteria in the soil. and newly germinated weeds, which is not conducive to the normal growth and development of flower seedlings

[0003] Both phosphorus and potassium are essential nutrients for the growth of flower seedlings. Although the nutrient soil contains a certain amount of phosphorus and potassium, most of them are slow-acting phosphorus and potassium, which cannot be directly absorbed by the roots of flower seedlings, resulting in slow growth of flower seedlings. , affect the normal growth and development of flower seedlings, therefore, the phosphorus and potassium in the nutrient soil need to be converted into soluble available phosphorus and potassium before they can be directly absorbed and utilized by plants

[0004] 80% of my country's mineral resources are associated mines. A large amount of valuable phosphorus, potassium and trace elements are stored in the tailings. The stockpiling of tailings requires a large amount of land. There is a great potential safety hazard in the tailings stockpile, which poses a serious threat to the property and life safety of the people in the surrounding areas.

[0005] Asbestos tailings are tailings stripped from asbestos ore processing, mainly powder, it is a dangerous solid waste with serpentine as the main component; due to the long-term stacking of asbestos tailings in large quantities, there is no way to recycle Utilizing and occupying land, polluting water bodies, destroying soil and polluting the atmosphere has seriously affected the development of production, transportation and mining areas, and has caused greater harm to the ecological environment and human beings in nearby areas.
