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

浪费的治疗和处置是一个比一年一度的更严重的问题。尤其是，二恶英，PCBS和内分泌疾病等环境微污染物的问题一直在日本成为一个社会问题。作者开发了一种名为Realacs的新垃圾填埋系统，该系统结合了循环性半恐惧垃圾填埋场和活化的覆盖土壤。进行的实验表明，激活的土壤在分解和/或吸附环境微污染物（例如重金属，有机污染物和DBP）等环境微污染物中的有效性。由于废物体积与每种处理技术之间的关系，例如中等处理技术，例如中等处理，回收和最终处置，随时间变化，理想的最终填充技术和陆上填充技术和陆上填充功能以及更改功能。通过这项项目研究已有3年了，这表明需要扩展垃圾填埋场所需的功能。除了作为最终倾销和净化站点的传统角色外，还有……更多功能，例如存储和保护潜在可重复使用的材料资源。根据上述提到的，作者提出了21世纪垃圾填埋场的“ Depo-Land”（存款垃圾填埋场）的概念，该地点应具有以下目的； 1）分类并分别存储废物，以便更好地监控资源和未来的资源（以外的填充方法），以净化和存款的实际功能，以便净化和固定量，以便将3.级的运行驱动驱动，以验证3.在诸如封闭系统之类的单独设施中，在垃圾填埋场操作过程中可能会平行使用顶盖。未来的垃圾填埋场还应具有远程监测措施系统，其中将生物测定技术（例如诱变测试）作为预防措施引入污染风险。通过这种方式，作者想强调适当的垃圾填埋场功能以满足未来全球现实的重要性，例如原材料和土地的稀缺。较少的
