牡蛎壳粉资源化利用研究进展

Progress of oyster shell powder resource utilization research

基于牡蛎壳所具有的高硬度、强耐腐蚀性和优良韧性等特性,梳理了牡蛎壳粉在环境治理与改良、建筑材料环保替代、可再生能源开发、食品与饲料营养成分保持和补充等方面的应用现状,指出,牡蛎壳粉可作为生物滤料和土壤改良剂,有效治理水体污染、促进土壤修复;可用作砂浆骨料替代品,并可制成生物阻燃剂等,减少建筑材料对自然资源的依赖,增强建筑材料的安全性能和使用性能;可作为一种高效环保催化剂,用于生物柴油、沼气等可再生能源的生产;还可作为钙补充剂、禽类饲料添加剂及抗菌剂,应用于食品与饲料行业,预防营养成分的流失并提高其安全性。尽管牡蛎壳粉的资源化利用展现出广阔的市场潜力,但其商业化进程仍受到加工成本、标准化和质量控制等技术的制约。未来的研究方向应集中在开发更高效的牡蛎壳粉处理技术,提升其在不同应用场景中的性能和价值,并探索其在新能源、生物医药等新兴领域的应用潜力,进一步推动牡蛎相关产业的可持续发展。

Based on the characteristics of oyster shell,such as high hardness,strong corrosion resistance and excellent toughness,the application status of oyster shell powder in environmental restoration,building materials,new energy development and food and feed industry was reviewed,and the application status of oyster shell powder in environmental management and improvement,environmental protection replacement of building materials,renewable energy development,nutrition maintenance and supplement of food and feed was also reviewed.It was pointed out that oyster shell powder could be used as a biofilter and soil conditioner to effectively control water pollution and promote soil restoration.It could be used as a substitute for mortar aggregate,and could be made into bio-flame retardants,etc.,to reduce the dependence of building materials on natural resources and enhance the safety and use performance of building materials;It could be used as an efficient environmental protection catalyst for the production of renewable energy such as biodiesel and biogas.It could also be used as a calcium supplement,poultry feed additive and antibacterial agent in the food and feed industry to prevent the loss of nutrients and improve their safety.Although the resource utilization of oyster shell powder showed broad market potential,its commercialization process was still restricted by processing costs,standardization and quality control technologies.Future research directions should focuse on developing more efficient oyster shell powder treatment technology,improving its performance and value in different application scenarios,and exploring its application potential in emerging fields such as new energy,biomedicine,etc.,so as to promote the sustainable development of oyster industry.
