项目摘要

As the results of this case study, we have developed another low-cost new landfill type which improves each function of the semi-aerobic landfill type. This is the so-called "Recirculatory Semi-aerobic Landfill Type" which is equipped with a leachate recirculation system. Main functions of this type are ;(1)To decrease the amount of leachate(2)To enhance the decomposition of waste(3)To improve the leachate qualityThis type of landfill serves to enhance the decomposition of waste and to improve the leachate quality through the introduction of air into the landfill site by means of leachate recirculation.Results of the field experiments for the recirculatory semi-aerobic landfill type in Malaysia show that initial COD_<Mn> concentrations of 5,200 mg/l decreased to 845 mg/l and NH^+_N of 1,440 mg/l decreased to 550 mg/l.From these results, it is shown that the recirculatory semi-aerobic landfill type improves leachate quality in practical use. Fig.1 shows a low cost system using the first Recirculatory Semi-aerobic Landfill type in Malaysia designed by the author. Based on the analysis of leachate quality from the landfill site, it was shown that this system performed well in Malaysia. Recently, the Malaysian Government has been using this system with a simple leachate physical treatment in the design of landfills based on our concept of "Landfill Type".

作为这一案例研究的结果，我们开发了另一种低成本的新型垃圾填埋场，改善了准好氧填埋场类型的各项功能。这就是所谓的“循环式准好氧垃圾填埋场”，它配备了渗滤液循环系统。这种类型的垃圾填埋场的主要功能是：(1)减少渗滤液的量(2)促进垃圾的分解(3)改善渗滤液的质量该类型的垃圾填埋场通过渗滤液的再循环向填埋场引入空气来促进垃圾的分解并改善渗滤液的质量。渗滤液浓度由5,200 mg/L降至845 mg/L，NH4+N由1,440 mg/L降至550 mg/l，说明循环准好氧填埋式渗滤液的水质在实际应用中得到了改善。图1显示了使用作者在马来西亚设计的第一个循环准好氧垃圾填埋场类型的低成本系统。根据对垃圾填埋场渗滤液质量的分析，该系统在马来西亚运行良好。最近，马来西亚政府根据我们的“垃圾填埋场类型”的概念，在设计垃圾填埋场时使用了这一系统和简单的渗滤液物理处理。
