This technology aims to address heavy metal contamination in oysters, product recycling and marine litter. Its core is the diatom oyster seed attachment base technology, which uses high-temperature extrusion and water-cooling processes to prepare materials. These materials leverage biological attributes to optimize the oyster food chain, providing high-efficiency attachment bases (800–1,000 pieces/m2). Performance: ammonia nitrogen adsorption rate of 35%–50%, antibacterial rate ≥ 98%, pH fluctuation ±0.2, service life of 5–10 years, achieving breakthroughs from heavy metal reduction to ecological aquaculture.
