项目摘要

Landfill sites in developing countries are mainly operated as the open dumping or the controlled tipping. such action is causing major environmental pollution. In the future, even though the intermediate treatment technology is adopted, such as a recovery of resources, an incineration and others, final disposal sites will be needed. From this point of view, the improvement of existing mlandfill site is an important for upgrading to the level of sanitary landfill.We investigated the landfill sites in major cities (Beijing, Xi'an, Changhai, and Guangzhou) of China for 3 years, and proposed a road to sanitary landfill from open dumping. The main results of this research are as follows ;1) In urban area, resource recovery and recycling from solid wastes were active.,2) Most of the existing landfill sites had a risk of explosion because they were an anaerobic landfill type without the gas venting system.,3) As the technical method for the stabilization of the landfill site, we set up the low cost typed gas venting pipes on the landfill site in Guangzhou.,4) On this case study, the bamboo, the useless srum cans and the construction debris were used as the gas venting pipes, so that the construction cost could be decreased.,5) The semiaerobic landfill system will be effective to accelerate the stabilization of landfill site.These case studies are the examples of improvement from the open dumping to the sanitary landfill, where is a lack of engineers and financial resources in China. And also these results from this research were high evaluated on the technical cooperation in the field of waste disposal and management in China.

发展中国家的垃圾填埋场主要作为开放式倾倒或受控小费运行。这种行动正在引起重大的环境污染。将来，即使采用了中级治疗技术，例如回收资源，焚化和其他人，也需要最终处置地点。从这个角度来看，现有的Mlandfill网站的改善对于升级到卫生垃圾填埋场的层面很重要。我们研究了主要城市（北京，西安，昌伊，昌伊）的垃圾填埋场，已有3年并提出了通往卫生垃圾填埋场的道路。这项研究的主要结果如下：1）在市区，从固体废物中的资源回收和回收利用是活跃的。排气系统。，3）作为垃圾填埋场稳定的技术方法，我们在广州的垃圾填埋场上建立了低成本的燃气通风管。4）在此案例研究中并将建筑碎片用作燃气管道，以便可以降低施工成本。，5）半恐怖垃圾填埋场系统将有效加速垃圾填埋场的稳定。倾倒到卫生垃圾填埋场，中国缺乏工程师和财政资源。而且，这项研究的这些结果对中国废物处理和管理领域的技术合作进行了高度评估。
