1results about How to "Improve ecological effect" patented technology

The application discloses a low-carbon solidified soil matrix and application. The matrix is made of dredged soil, biochar, slag and gypsum mixed in a specific ratio, and the preferred ratio (T1) is that the mass ratio of the dredged soil, the biochar, the slag and the gypsum is 60:15:10:15. By comparing the mechanical properties and the plant growth effects of different ratios (CK, T1, T2 and T3), it is found that the unconfined compressive strength of the T3 ratio (with the highest content of slag) is the highest (up to more than 3000kPa) after 60 days; however, the T1 ratio (with the highest content of biochar) exhibits the best ecological effect, including significantly promoting the growth of ryegrass, increasing the biomass, optimizing the carbon-nitrogen ratio of soil and enhancing the soil microbial activity, while maintaining sufficient engineering strength (about 1000kPa after 60 days) and excellent dry-wet cycle performance. The application realizes the balance between the mechanical and ecological restoration functions through the collaborative utilization of multi-source solid wastes, and provides an economic, environment-friendly and efficient solution for erosion areas.
