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".

作为该案例研究的结果，我们开发了另一种低成本的新垃圾填埋场类型，该垃圾填埋场改善了半运动垃圾填埋场类型的每个功能。这是所谓的“循环半卫星垃圾填埋场”，配备了渗滤液再循环系统。这种类型的主要功能是;（1）减少浸出量（2）以增强废物的分解（3），以改善浸出质量的质量，以通过将空气置于陆上的现场实验室中的陆地范围内，以提高浪费的分解，并通过将空气置于垃圾范围内，以改善浸润质量。表明最初的COD_ <mn> 5,200 mg/L的浓度降低至1,440 mg/l的845 mg/l和NH^+_ N降至550 mg/l。从这些结果中，它表明，循环半循环的陆填充物类型可改善渗透质量的实际使用。图1显示了使用作者设计的马来西亚的第一种循环半自动垃圾垃圾填埋场类型的低成本系统。基于对垃圾填埋场的渗滤液质量的分析，这表明该系统在马来西亚表现良好。最近，马来西亚政府一直在根据我们的“垃圾填埋场类型”的概念在垃圾填埋场中使用简单的渗滤液物理处理。
