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以露天倾倒或受控倾倒的方式运作。造成了严重的环境污染。今后，即使采用资源回收、焚烧等中间处理技术，也需要最终处置场。从这一点来看，现有填埋场的改善是提升到卫生填埋水平的重要途径，我们对中国主要城市（北京、西安、长海、广州）的垃圾填埋场进行了为期3年的调查，并提出了一条从露天倾倒到卫生填埋的道路。本研究的主要结果如下：1）在城市地区，固体废物的资源化和资源化是活跃的。2)大部分现有的堆填区都有爆炸的危险，因为它们是厌氧堆填区，没有气体排放系统。3)作为垃圾填埋场稳定化的技术手段，我们在广州某垃圾填埋场设置了低成本型排气管，4)本研究利用竹子、废弃的硫酸渣罐及建筑垃圾作为排气管，以降低建筑成本。5)准好氧填埋系统是加速填埋场稳定化的有效方法，这些案例研究是在我国缺乏工程师和财力的情况下，从露天填埋向卫生填埋的改进实例。并对中国在废物处理和管理领域的技术合作给予了高度评价。
