Embodiment 1

[0024] It should be noted that in Example 1, the content of each component in the fertilizer used to remediate manganese-contaminated soil was taken as a small value, and when preparing the fertilizer, the relevant parameters were set to a small value.

[0025] In this example, the fertilizer used to remediate manganese-contaminated soil consists of the following raw materials by weight: quicklime 20kg, blast furnace cinder 25kg, hematite 10kg, sodium nitrate 2kg, potassium sulfate 3kg, potassium chloride 5kg, sodium dihydrogen phosphate 30kg and 22.3kg of soil conditioner. Wherein, the soil conditioner is made up of the raw materials of following weight: 6.69kg of fern, 4.46kg of saponica, 5.575kg of wellside grass and 5.575kg of centipede grass.

[0026] In this embodiment, the preparation method of the fertilizer for repairing manganese-contaminated soil comprises the following steps:

[0027] S10. Grinding quicklime, blast furnace cinder and hematite into particles to obt...

Embodiment 2

[0032] It should be noted that in Example 2, the content of each component in the fertilizer used to repair manganese-contaminated soil was taken as a large value, and when preparing the fertilizer, the relevant parameters were set to a large value.

[0033] In this example, the fertilizer used to remediate manganese-contaminated soil consists of the following raw materials by weight: 50 kg of quicklime, 70 kg of blast furnace cinder, 50 kg of hematite, 6.5 kg of sodium nitrate, 8.6 kg of potassium sulfate, 11.8 kg of potassium chloride, phosphoric acid Sodium dihydrogen 65kg and soil conditioner 9kg. Wherein, the soil conditioner is made up of the raw material of following weight: 0.9kg of fern rosacea, 3.15kg of saponica, 2.25kg of wellside grass and 2.7kg of centipede grass.

[0034] In this embodiment, the preparation method of the fertilizer for repairing manganese-contaminated soil comprises the following steps:

[0035] S10. Grinding quicklime, blast furnace cinder and...

Embodiment 3

[0039] It should be noted that in Example 3, the content of each component in the fertilizer used to restore manganese-contaminated soil was taken as the median value, and when preparing the fertilizer, the relevant parameters were set as the median value.

[0040] In this example, the fertilizer used to remediate manganese-contaminated soil consists of the following raw materials by weight: 35 kg of quicklime, 50 kg of blast furnace cinder, 30 kg of hematite, 4.5 kg of sodium nitrate, 6 kg of potassium sulfate, 7 kg of potassium chloride, dihydrogen phosphate Sodium 45kg and soil conditioner 18kg. Among them, the soil conditioner is composed of the following raw materials: 6.3kg of fern rosacea, 3.6kg of saponica, 2.7kg of wellside grass and 5.4kg of centipede grass.

[0041] In this embodiment, the preparation method of the fertilizer for repairing manganese-contaminated soil comprises the following steps:

Abstract

The invention relates to the field of heavy metal prevention and control and in particular relates to fertilizer for repairing manganese polluted soil and a preparation method thereof. The fertilizerfor repairing the manganese polluted soil is prepared from the following raw materials in parts by weight: 20 to 50 parts of quick lime, 25 to 70 parts of blast furnace coal slag, 10 to 50 parts of hematite, 2 to 6.5 parts of sodium nitrate, 3 to 8.6 parts of potassium sulfate, 5 to 11.8 parts of potassium chloride, 30 to 65 parts of sodium dihydrogen phosphate and 9 to 22.3 parts of a soil improvement agent; the soil improvement agent is prepared from the following raw materials in parts by weight: 0.5 to 15 parts of aleuritopteris pseudo-farinosa and 2 to 18 parts of agriophyllum squarrosum.By adopting the fertilizer provided by the invention, the problem of the manganese polluted soil can be solved and nutrients are provided for the growth of plants.

Description

technical field [0001] The invention relates to the field of heavy metal prevention and control, in particular to a fertilizer for repairing manganese-contaminated soil and a preparation method thereof. Background technique [0002] It is understood that 96% of the batteries produced in my country are zinc-manganese batteries and alkaline manganese batteries, and their main components are heavy metals such as manganese, mercury, and zinc. Due to the current restrictions on waste battery treatment technology, there are still many heavy metals seeping out in various ways, polluting groundwater and soil, resulting in a waste of water and soil resources. [0003] Manganese is an essential micronutrient for plants. In agricultural planting, in order to promote the growth of plants, manganese-containing fertilizers are usually applied to the soil. If things go on like this, the manganese content in the soil will exceed the standard, which will easily lead to manganese poisoning i...
