1results about How to "Restoring ecological functions" patented technology

This invention relates to the field of soil pollution control technology, specifically to a microbial-phytoremediation method for heavy metal contaminated soil in mining waste sites. It includes a supporting base layer, on which a leachate collection layer, a heavy metal passivation and isolation layer, a microbial reinforcement layer, and a plant growth layer are sequentially arranged. This invention organically integrates multi-layered structural units to form a spatially ordered structure of leachate drainage—heavy metal passivation—microbial loading—plant growth. It employs immobilized functional microbial agents and embeds multi-parameter sensing devices to establish a monitoring-feedback-control closed-loop system. Simultaneously, hyperaccumulating plants are planted and inoculated with arbuscular mycorrhizal fungi, achieving a shift from an open-loop passive mode to a closed-loop active collaborative mode, avoiding problems such as delayed remediation response, poor synergy, and insufficient long-term stability.
