韩国的很多岛屿面临着水源安全和供水问题,特别是那些远离大陆的小岛供水条件更差。为了向小岛供水,开发了两套涉及运水、地下水开采和淡化咸水的替代方案,但这些方案耗能多且成本高,需关注其安装和运行过程。雨水收集(RWH)耗能少成本低,是一种可持续性的方案,但目前对这些地区内的雨水收集系统缺乏实践或综合研究,从而阻碍了系统的推广。探讨了古吉(Gu ja)岛现有RWH系统存在的问题,从水量和水质方面提出了技术改进建议。系统设计经过修改,并通过使用如码头建筑物这样的真空区对系统进行扩容后,可从水量和水质方面满足该岛的用水需求。据估计,RWH在韩国这样的不利于雨水收集的气候条件下是可行的供水方案,这就意味着对于世界上面临缺水的其他地区,RWH技术具有更大的应用潜力。
Many islands in South Korea face water security and water supply problems, especially those on islands far from the mainland. In order to supply water to the island, two sets of alternatives involving the transport of water, groundwater and desalination of salt water have been developed, but these solutions are more energy-intensive and costly, paying attention to their installation and operation. Rainwater harvesting (RWH) is less costly and less costly and is a sustainable solution, but current practice of rainwater harvesting systems in these areas is either poor or comprehensive and has hampered the promotion of the system. The problems existing in the existing RWH system in Guja Island were discussed, and suggestions for technical improvement were put forward in terms of water quantity and quality. After the system design was modified and the system was expanded by using a vacuum zone such as a dock building, the island’s water needs could be met in terms of water and water quality. It is estimated that RWH is a viable water supply solution in a climate such as South Korea, which is detrimental to rainwater harvesting, which means that RWH technology has greater potential for use in other parts of the world where there is water scarcity.
