Decentralized drinking-water systems are an important element in the process of reaching the Millennium Development Goals, as centralized systems are often deficient or non-existent in developing and transition countries (DC and TC). Most water-quality problems are due to hygiene factors and pathogens. A range of decentralized systems is available to counter these problems, including thermal and/or UV methods, physical removal and chemical treatment.This review focuses on decentralized systems that treat the potable water (drinking and cooking) of a single household (point-of-use systems) or a community (small-scale systems). For application in DC and TC, important boundary conditions for decentralized systems include low costs, ease of use, sustainability, low maintenance and independence of utilities (energy sources). Although some low-cost systems are available, their application is limited by time-consuming daily operation and maintenance. Other systems are too expensive for the poor populations of DC and TC and in most cases do not fulfill the system requirements described above. Point-of-use systems based on membranes are commercially available and are designed to operate on tap pressure or gravity.Membrane systems are attractive since they provide an absolute barrier for pathogens and remove turbidity, thus increasing the palatability of the water. The costs of membrane have decreased rapidly during the last decades and therefore membrane systems have also become within reach for application in low-cost applications in DC and TC. Some membrane systems rely on gravity as a driving force, thereby avoiding the use of pumps and electricity. On the basis of the present literature data, no small-scale systems could be identified which meet all the requirements for successful implementation. Furthermore, in the available literature the performance of highly fouling water types has not been reported. For such cases, more extensive studies are required and a need for suitable pre-treatment was identified.It can be concluded that there are good prospects for decentralized systems based on membranes, but that a need exists for research and development of systems with low costs and low maintenance, specifically designed for DC and TC. 相似文献

Design considerations for smoke control systems have been addressed by numerous researchers and practicing engineers. However, papers discussing the actual observed performance of smoke control systems are less frequently encountered. The following three papers address the testing of smoke control systems from two perspectives. First, suggested procedures for testing smoke control systems are described relative to test methodology, system parameters requiring evaluation, and measurement systems. Second, the performance of actual systems is described as observed in tests. 相似文献

深部厚顶煤巷道让压型锚索箱梁支护系统现场试验对比研究 总被引:1,自引:0,他引:1
针对巨野矿区深部高地应力厚顶煤巷道支护特点,以“先抗后让再抗”支护理念为指导,研制高强让压型锚索箱梁(PRABB)支护系统。该系统具有预紧力损失小、定量让压、支护力传递效果好、护表面积大等特点。分别以箱型支护梁和矿用12#工字钢为托梁设计了横梁、纵向单梁和纵向双梁共6种支护系统。以赵楼煤矿深部厚顶煤巷道为工程背景,利用数值试验对其支护效果进行初步分析,并在3302工作面顺槽进行6种支护系统的现场试验对比研究。现场试验结果表明:(1) 相对于原支护方案,6种锚索梁支护系统均能有效控制巷道围岩变形;(2) PRABB支护系统试验段巷道支护效果整体优于工字钢锚索梁方案,前者围岩变形量比后者小15%~25%;(3) 纵向单梁支护系统对巷道围岩的控制效果最好,纵向双梁支护系统次之,横梁支护系统相对较差。根据试验结果对钢梁不同布置方式的围岩控制机制进行分析表明:纵向单梁支护系统可有效控制厚顶煤巷道顶板关键部位的变形,调动围岩自承能力,使巷道变形得到较好控制。在深部厚顶煤巷道支护时,采用PRABB支护系统纵向单梁方案,可达到经济有效控制巷道围岩变形的目的。 相似文献
