Characteristics and advantages of zeolite soil remediation technology and products.
Zeolite soil remediation technology overcomes the high cost and large amount of physical remediation, avoids the damage of chemical remediation to the original soil ecosystem, eliminates the disadvantages of ecological risks caused by bioremediation, and uses the unique characteristics of natural zeolite to achieve the role of soil restoration.
Zeolite soil remediation agent is a functional soil remediation conditioner prepared from natural zeolite as raw material. It has a well-developed pore structure, large specific surface area, outstanding adsorption performance and unique ion exchange properties.
This technology and product can effectively solidify heavy metal pollutants, significantly reduce their biological activity, and improve soil structure, and the cost is relatively low and cost-effective, which has huge promotion value and application space.
1.Through dissolution precipitation, ion exchange, adsorption, redox, complexation and other effects, the heavy metal pollutants in the soil can be effectively solidified, the content of heavy metal pollutants in the soil can be significantly reduced, the heavy metal pollutants absorbed by crops can be prevented, and the risk of pollutants being transferred to the food chain can be reduced.
2.The porous structure, electrostatic field and proton acid produced by zeolite soil remediation agent have the effect of slow release, decomposition and reduction of organic pollutants such as chemical fertilizers, pesticides, herbicides, and insecticides, which can improve soil quality, improve the efficiency of chemical fertilizer and pesticide use, reduce planting costs, and increase yield.
3.The electrostatic field of zeolite soil remediation agent can adsorb soil particles and form soil aggregates, thereby improving soil structure and regulating soil water content, improving soil permeability, and regulating soil pH value.
4.It is a natural inorganic substance with stable properties, which has strong self-integration and adaptability with the soil, and there is no secondary pollution problem.
5.China is the country with the most abundant natural zeolite resources in the world, with billions of tons of reserves in North China alone, and the preparation of soil remediation agents from natural zeolite has resource guarantee and cost advantages, which is conducive to the large-scale application of zeolite soil remediation technology.
The application of zeolite soil remediation agent is cost-effective.
For a long time, immature application technology, backward production equipment, and unstable product quality are the key factors restricting the large-scale application of zeolite soil remediation technology in China.
Since 2012, SDIC Shengshi Chengde Science and Technology Co., Ltd., together with the Chinese Academy of Agricultural Sciences, Beijing Academy of Agriculture and Forestry Sciences, China University of Geosciences, Hunan Agricultural University, Hebei Agricultural University and other units, has successfully developed zeolite soil remediation conditioner, mastered the core key technology, the product has reached the international advanced level in the same industry, filled the domestic gap, applied for a national invention patent, and in 2015, planned to invest in the construction of an annual output of 3 million tons of zeolite environmental protection new material industrial park in Chengde City, Hebei Province. After the project reaches production, it can remediate 6 million mu of polluted soil annually.
SDIC Shengshi has carried out field and greenhouse applications in Beijing, Hebei, Hunan, Guangdong, Heilongjiang and other provinces and cities, and has achieved remarkable results, with the removal rate of heavy metals in the soil reaching more than 50%, and the removal rate of heavy metals in crop fruits reaching more than 30%, and the yield increase effect is obvious, increasing the yield by 20 to 40% per mu, and the cost is relatively low, and the repair cost per mu does not exceed 500 yuan.

Soil conditioner (loosening soil) is a kind of polymer, high activity, pollution-free, residue-free natural degradation of biopolymer, strong stability.
1. Soil loosening agent is safe, efficient, broad-spectrum, unique in mechanism, suitable for various types of soil, no pollution to the environment, no ***.
2. Apply under moist soil conditions, generally 3 5 days can observe the soil turning blue and not digging, and the observation methods are: Turning the ground with a hoe or shovel, feeling less labor, easy to enter the hoe or shovel. When irrigating the ground with water, the water seeps quickly, and bubbles can be observed, and the irrigation time is prolonged.
It is easy to pull the grass uprooted. The pedals have a crispy feel. In addition to observing soil changes, there will be obvious differences in the growth and development of aboveground crops, especially fast-growing crops, whether it is from plant height, stem thickness, leaf size, leaf color, fruit development speed, fruit shape.
3. After use, it can promote the formation of good aggregate structure of soil particles, increase the porosity of the soil, improve the permeability of the soil, coordinate the water, fertilizer, gas and heat in the soil, increase the soil fertility, and facilitate the activities of soil microorganisms, thereby reducing the salinity of the soil, reducing the harm of salinization and acidification, increasing the beneficial microorganisms in the soil, the development of crop roots, enhancing the resistance to diseases, and reducing the occurrence of soil-borne diseases.
4. Crop rotten roots are often called "plant cancer", and the reason for the occurrence of this disease is mostly due to serious soil compaction or waterlogging, resulting in poor soil permeability, resulting in suffocation and death of the root system and rotting, and the phenomenon of rotten roots and rotten roots occurs. The use of soil loosening agent can effectively improve soil permeability, deepen the deep layer, and regulate the "water, fertilizer, gas and heat" in the soil, which is conducive to the survival and development of aerobic microorganisms in the soil soil. If the number of aerobic microorganisms increases, the harmful substances will be oxidized and decomposed, thereby greatly reducing the harmful substances in the soil and preventing the occurrence of root rot and root rot disease, or even not occurring.
