Environmental improvement method and environmental improvement materials for underwater or beach

机译:水下或海滩环境改善方法及环境改善材料

摘要

PPROBLEM TO BE SOLVED: To provide a method for improving the environment especially in water, shallow water/tidal flat, etc., to form an environment suitable as a habitat of organisms by using a laying material available in large quantities at a low cost. PSOLUTION: Granulated blast furnace slag containing 90 mass% slag particles having a particle diameter of 0.5 mm and preferably 70 mass% slag particles having a particle diameter of 1.0 mm is laid on sea bottom or on a beach. Granulated blast furnace slag has the nature/appearance close to those of natural sand, exhibits chemical action to clean the bottom and water and functions as a silicate ion releasing source and, accordingly, it is suitable as a laying material. Furthermore, the slag has a controlled particle size distribution, it can form a sea bottom suitable as a habitat of bottom organisms. A safe beach is formed owing to extremely small content of needle-like particles. PCOPYRIGHT: (C)2004,JPO

要解决的问题:提供一种改善环境的方法,特别是在水,浅水/滩涂等环境中,通过使用大量可用的铺垫材料来形成适合作为生物栖息地的环境。低成本。

解决方案:将含有90质量%的粒径为0.5mm的炉渣颗粒并且优选为70质量%的粒径为1.0mm的炉渣颗粒的高炉矿渣置于海底或海滩上。粒状高炉矿渣的性质/外观与天然砂相似,具有化学作用以清洁底部和水,并具有释放硅酸盐离子的作用,因此适合用作铺层材料。此外,炉渣具有受控的粒度分布,它可以形成适合作为底部生物栖息地的海底。由于极少量的针状颗粒,形成了一个安全的海滩。
