Problems solved by technology

Most of its bio-glues are added with chemical substances such as plasticizers, gels, preservatives, antioxidants and reinforcing agents, and they are all sealing colloids without air permeability and water-locking properties, and do not have the effect of improving tailings. There is a big difference in the invented bioglue

Abstract

The invention relates to a natural plant adhesive for ecological restoration of a tailing area and a preparation method thereof. The adhesive comprises the following raw materials in parts by weight:30-35 parts of corn starch, 10-13 parts of glutinous rice flour, 20-23 parts of peat, 10-15 parts of beer grains, 6-8 parts of humic acid, and 4-5 parts of rice hull carbon. According to the natural plant adhesive for ecological restoration of the tailing area and the preparation method thereof, the salinization of the tailings are neutralized by utilizing the characteristics of meta-acid of the raw material to create conditions for plant growth; the natural plant adhesive is a natural plant product and can be decomposed, so that the technical problem that a plant cannot grow due to nutritional deficiency in the tailing area is changed; the recycling utilization and reasonable utilization of tailings are realized, reasonable collection is made for heavy metals due to the enrichment effectof plants, a series of pollution of tailings caused by heavy metals are eliminated so as to solve the problem of tailing pollution, and the ecological environment of the mine area can also be improvedand restored.

Description

technical field [0001] The invention belongs to the field of soil pollution control, and in particular relates to a natural plant adhesive used for ecological restoration of tailings areas and a preparation method thereof. Background technique [0002] Mineral resources occupy an unshakable position in social development and human life. The rapid development of the mining and dressing industry has caused a sharp increase in the discharge of iron tailings and waste rocks. Due to its low comprehensive utilization rate (the comprehensive utilization rate is only 15%), Lead to serious accumulation of iron tailings and waste rock. At present, the total stockpiling of tailings in my country has reached 8.046 billion tons, of which the stockpiling of iron tailings has reached 6.2 billion tons. The stockpiling of tailings occupies a large amount of land resources. Every year, about 1.5 million square meters of land is destroyed due to mining activities nationwide. 2 , the stacking...
