Adopting natural wood raw materials, it has no secondary pollution to soil, and its porous structure can effectively adsorb and fix heavy metal ions and degrade petroleum pollutants. It can improve soil fertility and microbial habitat, promote the restoration of soil ecological function, and is suitable for in-situ remediation of contaminated soil. It is easy to apply, can be directly mixed with soil, reducing construction costs and difficulty for remediation projects.
The raw material is natural hardwood, with activation temperature of 750-850℃. The heavy metal adsorption capacity is ≥25 mg/g, pH value is 6.5-7.5, ash content is ≤10%, moisture content is ≤6%, average particle size is 30 μm, no toxic additives, organic matter content is ≥30%. It is packed in 25kg biodegradable woven bags, with a shelf life of 3 years, and needs to be stored in a cool and dry place.
It is applicable to remediation of heavy metal contaminated farmland, petroleum polluted soil in oil extraction areas, contaminated soil in industrial parks and contaminated soil in landfills. It can reduce the absorption of heavy metals by crops, improve soil quality and restore ecological functions, helping relevant departments and enterprises solve soil pollution problems and ensure agricultural product safety and ecological environment safety.
