摘要： The present invention uses fish bones and fish hard parts to remediate, clean-up, stabilize, immobilize, or otherwise treat metal-contaminated water, soil or waste of any sort. The fish bones and fish hard parts can be mixed in with soils and wastes, or emplaced as a permeable reactive barrier in a trench or excavation, or emplaced as a liner or barrier surrounding a waste form, disposal site, or contaminated site. All that is needed is intimate contact between the fish bones and fish hard parts and the contaminated waste form, soil particles, or water. In a system of, for example, soil, waste, groundwater, surface water, waste streams, or the digestive tracts of animals, the presence of fish bones and fish hard parts reduces the amount of metal that can mobilize and migrate out of the system. Fish bones and fish hard parts remove metals from waters passing through the system or originating within the system. Fish bones and fish hard parts reduce the bioavailability of metals to organisms coming into contact with the system and from water leaving the system. The fish bones and fish hard parts can be mixed with any other material, e.g., gravel, sand, clay, zeolites, soils of all types, iron filings, cement, compost, straw, or organics of all types.
摘要翻译：本发明使用鱼骨和鱼类硬部件来修复，清理，稳定，固定或以其他方式处理任何种类的金属污染的水，土壤或废物。鱼骨和鱼的硬部分可以与土壤和废物混合，或者作为渗透反应性屏障在沟槽或挖掘中放置，或作为围绕废物形式，处置场所或污染场地的衬里或屏障放置。所需要的是鱼骨和鱼类硬部件之间的紧密接触以及污染的废物形式，土壤颗粒或水。在例如土壤，废物，地下水，地表水，废物流或动物的消化道的系统中，鱼骨和鱼类硬部件的存在减少了可以移出和移出系统的金属的数量。鱼骨和鱼的硬质部件从通过系统的水域或系统内的水中清除金属。鱼骨和鱼类硬部件会降低金属与生物体的接触生物体的生物利用度和离开系统的水。鱼骨和鱼的硬部分可以与任何其他材料混合，例如砾石，沙子，粘土，沸石，各种土壤，铁屑，水泥，堆肥，秸秆或各种有机物。
