Method for preparing planting soil from industrial wastes

Abstract

The invention discloses a preparation method of planting soil prepared from industrial waste, and relates to the technical field of preparation of the planting soil prepared from the industrial waste, and the preparation method of the planting soil prepared from the industrial waste comprises the following steps: step 1, crushing mine waste residues by using a crusher; according to the invention, the planting soil is prepared by crushing waste residues, coal gangue, coal cinder and mineral separation residues abandoned by mining and matching the crushed waste residues, coal gangue, coal cinder and mineral separation residues with traditional Chinese medicine residues, waste bacteria sticks and sludge obtained after urban sewage treatment according to a certain proportion, and the traditional Chinese medicine residues, the waste bacteria sticks and the urban water treatment sludge can be independently mixed with slag to prepare the soil, or can be mixed for many times to prepare the soil; according to the method, waste residues, coal gangue, coal cinder and mineral separation residues which are abandoned by mining are smashed and matched with traditional Chinese medicine residues, waste bacteria sticks and sludge obtained after urban sewage treatment according to a certain proportion to prepare the planting soil, and the traditional Chinese medicine residues, the waste bacteria sticks and the urban water treatment sludge can be independently mixed with slag to prepare the soil and can also be mixed for many times to prepare the soil.

Description

Technical Field

[0001] The invention relates to the technical field of preparing planting soil from industrial waste, and in particular to a method for preparing planting soil from industrial waste. Background Art

[0003] Although Chinese herbal medicine residues, discarded mushroom sticks after mushroom processing, and water treatment sludge are used as fertilizers in various parts of China, there is no precedent for mixing them with mining waste to make soil. In other words, the above wastes have not yet been used more scientifically and rationally in China. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides a method for preparing planting soil from industrial waste, which solves the problem that most of the existing various types of slag, coal gangue, etc. are scattered around mines, and most of them are backfilled with slag after mining, and then covered with soil on the backfilled slag, and then afforestation is carried out. At present, these mine wastes have not been recycled;

[0005] Although Chinese herbal medicine residues, discarded mushroom sticks after fungus processing, and water treatment sludge are used as fertilizers in various parts of China, there is no precedent for mixing them with mining waste to make soil. In other words, there is no technical problem in China to utilize the above wastes in a more scientific and reasonable way.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a method for preparing planting soil from industrial waste, the steps of the method for preparing planting soil from industrial waste are as follows:

[0007] Step 1: crush the mine waste with a crusher;

[0008] Step 2: Pile up and ferment the Chinese medicine residue, waste mushroom sticks, and water treatment sludge;

[0009] Step 3: Fully mix the fermented Chinese medicine residue, waste mushroom sticks, and water treatment sludge with the crushed mine waste residue at a ratio of 20%-50%.

[0010] Preferably, in step 1, the mine waste is crushed by a crusher into particles smaller than 50 mesh.

[0011] Preferably, in step 2, the fermentation time in summer is often 40 days, the fermentation time in spring and autumn is often 60 days, and the fermentation time in winter is often 90 days.

[0012] Beneficial effects: The present invention provides a method for preparing planting soil from industrial waste. The present invention utilizes waste slag, coal gangue, coal slag, and mineral processing residues abandoned in mining, which are crushed and mixed with a certain proportion of traditional Chinese medicine slag, waste mushroom sticks, and sludge from urban sewage treatment to produce planting soil. The traditional Chinese medicine slag, waste mushroom sticks, and urban water treatment sludge can be mixed with slag alone to produce soil, or they can be mixed for multiple times to produce soil. DETAILED DESCRIPTION

[0013] The present invention will be further described below in conjunction with embodiments;

[0014] Example 1: A method for preparing planting soil from industrial waste, the steps of the method for preparing planting soil from industrial waste are as follows:

[0015] Step 1: Use a crusher to crush the mine waste into particles smaller than 50 mesh;

[0016] Step 2: Pile up and ferment the Chinese medicine residue, waste mushroom sticks, and water treatment sludge. The fermentation time in summer is usually 40 days, in spring and autumn it is usually 60 days, and in winter it is usually 90 days;

[0017] Step 3: Fully mix the fermented Chinese medicine residue, waste mushroom sticks, and water treatment sludge with the crushed mining waste residue at a ratio of 20%.

[0018] Example 2: A method for preparing planting soil from industrial waste, the steps of the method for preparing planting soil from industrial waste are as follows:

[0020] Step 2: Pile up and ferment the Chinese medicine residue, waste mushroom sticks, and water treatment sludge. The fermentation time in summer is usually 40 days, in spring and autumn it is usually 60 days, and in winter it is usually 90 days;

[0021] Step 3: Fully mix the fermented Chinese medicine residue, waste mushroom sticks, and water treatment sludge with the crushed mining waste residue at a ratio of 30%.

[0022] Example 3: A method for preparing planting soil from industrial waste, the steps of the method for preparing planting soil from industrial waste are as follows:

[0023] Step 1: Use a crusher to crush the mine waste into particles smaller than 50 mesh;

[0024] Step 2: Pile up and ferment the Chinese medicine residue, waste mushroom sticks, and water treatment sludge. The fermentation time in summer is usually 40 days, in spring and autumn it is usually 60 days, and in winter it is usually 90 days;

[0026] Requirements of organic matter, nitrogen, phosphorus and potassium content in ordinary farmland

[0027] The organic matter content reaches 2%-3%

[0028] Nitrogen content reaches 150-200mg / kg

[0029] Phosphorus content reaches 60-100mg / kg

[0030] Potassium content reaches 100-150mg / kg

[0032] Organic matter content 30%-50%

[0033] Nitrogen content 3%-8%

[0034] Phosphorus content 0.3%-1.8%

[0035] Potassium content 1%-3%

[0044] Average phosphorus 2.32%

[0045] Average potassium 1.42%

[0046] From the above index calculation and analysis, we can draw the conclusion that as long as 20% of one of the materials is added to the crushed slag, the requirements for general farmland soil planting can be met.
