Iron tailing soil improvement agent and iron tailing soil improvement method

Abstract

The invention relates to an iron tailing soil improvement agent and an iron tailing soil improvement method. The iron tailing soil improvement agent comprises biochar, rice husks, ceramsite, organic fertilizers, attapulgite powder and planting soil. A mass ratio of the biochar to the rice husks to the ceramsite to the organic fertilizers to the attapulgite powder to the planting soil is (0.5-3):(0.2-1):(0.5-1.5):(1-4):(1-2.5):(1.0-2.2). The iron tailing soil improvement agent and the iron tailing soil improvement method have the advantages that the particle size of soil can be improved by theaid of the iron tailing soil improvement agent, the loss rate of water in the soil can be eased, the water retention capacity can be enhanced, organic matters can be quickly and effectively supplemented, the content of organic matters in tailing can be effectively increased, and suitable environments can be provided for plant growth; the rice husks and the ceramsite are matched with one another, the porosity of iron tailing soil can be improved, the hardening degree of the soil can be lowered, the tailing soil can keep in excellent gas-permeable and soft states for a long term, accordingly, the iron tailing soil improvement agent and the iron tailing soil improvement method are favorable for respiration of animals and plants in the soil, and the survival rate can be increased.

Description

technical field [0001] The invention relates to an iron tailings soil improver and an iron tailings soil improvement method, belonging to the technical field of environmental protection. Background technique [0002] The stockpiling of iron tailings not only occupies a large amount of agricultural and forestry land, resulting in a waste of resources, but also brings serious pollution and harm to the living environment of human beings and destroys the ecological balance. As the amount of tailings increases, the occupied land area will continue to expand, which will lead to an imbalance of land resources in the area where the tailings ponds are located. At present, most of the tailings are in an abandoned state. The long-term accumulation has damaged the local ecological environment and polluted the air environment when exposed to the wind. Poor water and soil conservation capabilities are likely to pollute water resources; and the tailings dam failure will cause serious damag...

AI Technical Summary

Problems solved by technology

Therefore, reducing the waste of land resources, reducing tailings pollution, and optimizing the mine environment can improve land utilization. At present, there are technical measures for tailings soil improvement, but the effects are not ideal, and it cannot provide a good environment for plant growth. Improvement methods The cost is relatively high, the improvement period is long, and the effect is slow
