项目摘要

The treatment and disposal of waste is a more serious issues then ever year by year.Especially, the problems of environmental micropollutants such as Dioxins, PCBs and Endocrine disrupters has been become a social issues in Japan. The authors have developed a new landfill system, named REALACS, which combines the recirculatory semiaerobic landfill and the activated cover soil. The conducted experiments showed the effectiveness of the activated cover soil on decomposing and/or adsorbing the environmental micropollutants such as heavy metals, organic pollutants and DBP.As the relationships between waste volume and each treatment technique, such as intermediate treatment, recycling and final disposal, change over time, ideal final disposal, landfill technologies and landfill functions are also changing. Through this project study for 3 years, it suggests that the functions required for landfill sites need to be extended beyond the conventional role as a final dumping and purifying site to … More include functions such as storing and safekeeping of potentially reusable material resources. Based on the above mentioned, the authors propose the concept of "Depo-Land" ( Deposit Landfill) for landfills in the 21st century, where sites should have the following aims ;1)to classify and separately store wastes, allowing better monitoring and future reuse of the resources (separate landfilling method),2)to have purifying and deposit functions (for example, using the REALACS system),3)to safely dispose unrecoverable wastes in a separate facility such as a closed system, which could have a parallel use of the top cover during the landfill operations.The future landfill sited should also have a long-range monitoring measure system in which bioassay techniques such as mutagenic test are introduced as a prevention measure for pollution risks. In this way, the authors would like to emphasize the importance of adequating the function of landfill in order to meet future global realities such as the scarcity of raw materials and land. Less

废物的处理和处置更为严重，这是环境微污染物的问题。在分解和/或吸附微污染物（例如废物量和每个技术之间的重金属）时，将半恐惧的垃圾填埋场和激活的覆盖物结合在一起垃圾填埋场的功能也通过项目研究进行了3年的变化，这表明垃圾填埋场需要以最终的垃圾垃圾倾倒和净化站点的趋势超越……更多的功能，包括存储和可重复使用的材料资源。基于大约提到的，作者提出了对垃圾填埋场的“ depo-land”（存款）垃圾填埋场的概念，具有以下AMS Oring和未来的资源（单独垃圾填埋方式），2），2）进行净化和净化。存款功能（例如，使用RealACS系统），3）在垃圾填埋场操作过程中并行使用顶盖，安全处理不可恢复的废物。未来的垃圾填埋场位置也具有较长的范围监测措施系统，其中生物测定技术在其中采用此类生物测定技术。作为ASUR污染的风险，诱变测试被引入
