Comparison between Jap. & Ital.Landfill and study of New

根据对日本和意大利的最终处置场进行调查所收集的资料，对下列条款进行了研究。通过对福冈市和卡利亚里市部分垃圾填埋场产生的气体和渗滤液的数据分析，明确了产生的气体和渗滤液的物理化学性质.通过对两国衬砌系统的考察，研究了如何防止渗漏和防止地基土污染.讨论了最终处置场抗震再活化的安全性，并澄清了不会发生再活化的问题。对如何保护最终处置场周围地区不受环境污染进行了研究，研究仍在继续，迄今为止取得的成果已在KNCT研究报告（1998年）中报告。对两国最终处置场最终土地利用的实际情况进行了调查，以制定更实用、更合理的方法。R.Cossu教授应邀到KNCT讨论联合研究的结果，并相互交流有用的信息。为了提出一种新的固体废物最终处理系统，今后将继续积极开展联合研究。

On the basis of information collected from the investigation of final disposal sites both in Japan and Italy, the following articles have been studied.1. From the data of Generated Gas and Leachate from some final disposal sites in Fukuoka-City and Cagliari-City, the physical and chemical properties ofGenerated Gas and Leachate are clarified.2. From the investigation of the Lining Systems in both country, how to protect the leakage and the contamination of ground soil are being studied.3. The safety of requefaction of final disposal sites against earthquake and clarification that requefaction will not occur, were discussed.4. How to protect the surrounding area of final disposal sites from environmental pollution has been studied and studies are still continuing, the results obtained so far have been reported in the paper of the research report of KNCT(1998).5. The actual circumstances of ultimate land use of final disposal sites in both countries has been investigated in order to develop a more useful and reasonable method.6. Prof.R.Cossu was invited to KNCT to discuss the results of the Joint Research and exchange useful information with each other. In order to present a new system for final disposal sires of solid waste, Joint Research will be continued actively in the future.
