This invention provides a slope protection material composed of recycled heavy metal tailings and its preparation method. The material includes: recycled heavy metal tailings treated with a heavy metal chelating agent as a heavy metal ion capture agent, the chelating agent being added at 0.05%–0.2% of the heavy metal tailings weight; recycled heavy metal tailings as aggregate, which is mixed with natural soil to form a base material at a ratio of 1:1.5–2.5; fine aggregate and fine sand, added at 5%–10% of the base material weight; and high-viscosity industrial-grade sodium alginate added as a water-retaining and reinforcing agent, added at 0.5%–2.0% of the base material weight. Additionally, 28% organic matter is added to the base material. The application of this invention effectively solves the problems of ineffective utilization of recycled heavy metal tailings and excessive use of scarce natural soil in existing technologies, and also addresses the issues of weak strength, poor effectiveness in steep slope treatment, and poor stability in existing slope protection materials.

This invention provides a method for culturing aerobic methanogenic microorganisms in mangrove sediments, belonging to the field of microbial technology. The method comprises five steps: culture medium preparation, sample pretreatment, mud system preparation, aerobic environment construction, and isothermal incubation. The culture medium contains basic salts, macroelements, microelements, and vitamins adapted to the brackish water environment of mangroves. By constructing a stable aerobic culture system, the efficient enrichment of aerobic methanogenic microorganisms in mangrove sediments is achieved. This invention is specifically adapted to the environmental characteristics of mangrove sediments, filling the gap in aerobic methanogenic microorganism enrichment and cultivation technology in mangrove ecosystems. It can stably achieve the cultivation and enrichment of aerobic methanogenic microorganisms, providing reliable technical support for elucidating the aerobic methanogenesis process in coastal mangrove wetlands, isolating and purifying aerobic methanogenic functional microorganisms, and expanding the methanogenic microbial resources of mangrove ecosystems.
