Organic fertilizer prepared from red mud and production process of organic fertilizer

Abstract

The invention discloses an organic fertilizer prepared from red mud and a production process of the organic fertilizer. The organic fertilizer includes animal excrements, straw, distillers' grains, saw dust, red mud, humic acid, low-molecular-weight organic acid, edible mushroom waste, bone meal, an antiviral agent and a microbial agent. The organic fertilizer has the advantages that the animal excrements, red mud, saw dust and straw are adopted as the raw materials, waste utilization is realized, environmental pollution is reduced, and the problem that the red mud cannot be utilized and pollutes the environment is solved. The low-molecular-weight organic acid and aluminum ions in the organic fertilizer cannot be absorbed by plants and fail after being exchanged and complexed, and nutrients in the red mud and other raw materials interact and can provide calcium, silicone and corresponding trace elements for crops; iron, silicone, calcium, magnesium and other nutrient elements are addedon the basis of an original organic fertilizer, the growth of the crops is promoted, diseases and insect pests can be reduced, an iron fertilizer is replaced, and a certain improvement effect on soilis realized.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to an organic fertilizer made from red mud and a production process thereof. Background technique [0002] Red mud is the polluting waste slag discharged during the extraction of alumina in the manufacturing industry. Generally, for every ton of alumina produced, 1.0-2.0 tons of red mud is incidentally produced. As the world's fourth largest producer of alumina, China's annual discharge of red mud is as high as Tens of millions of tons belong to the general solid Class III solid waste. Because the chemical alkali combined with red mud is difficult to remove and has a large content, and it also contains iron, aluminum and other impurities, it has been difficult to harmlessly utilize red mud. Experts from all over the world have conducted a lot of scientific research on the comprehensive utilization of red mud, but such research has not made much progress. Therefore, the treatment...

[0002] Red mud is the polluting waste slag discharged during the extraction of alumina in the manufacturing industry. Generally, for every ton of alumina produced, 1.0-2.0 tons of red mud is incidentally produced. As the world's fourth largest producer of alumina, China's annual discharge of red mud is as high as Tens of millions of tons belong to the general solid Class III solid waste. Because the chemical alkali combined with red mud is difficult to remove and has a large content, and it also contains iron, aluminum and other impurities, it has been difficult to harmlessly utilize red mud. Experts from all over the world have conducted a lot of scientific research on the comprehensive utilization of red mud, but such research has not made much progress. Therefore, the treatment and comprehensive utilization of red mud waste has become a worldwide problem, and the sale of red mud The method of stacking and disposal on the seabed or on land is the main method adopted by Namibia. However, with the development of the aluminum industry, the amount of red mud discharged from the production of alumina is also increasing, and a series of problems caused by stacking and disposal have emerged, causing serious environmental issues

[0003] Because red mud is rich in potassium oxide, iron oxide, calcium oxide, magnesium oxide and other trace elements, it has certain advantages in improving soil and increasing the yield of agricultural products, but there are relatively few reports on the use of red mud in fertilizers.
