雨水资源的利用及其实验

非常规水资源,特别是雨水资源的利用已成为解决缺水问题的重要途径．在分析国内外雨水资源研究现状的基础上,对雨水利用技术进行了介绍和探讨．通过在某单位大厦所建立的雨水利用系统的实验研究,分析了降雨量与集雨量,及降雨强度与集雨量的关系,并按有关标准对降雨过程进行了采集、处理和水样分析．结果表明,集雨量与降雨量和降雨强度并不存在线性关系,而且在降雨量大于20 mm,或平均降雨强度大于0．04 mm／min的情况下,该系统才有收水的可能．雨水经处理后的水质优于有关国家设计标准,完全可用于城市生活杂用水．

Utilization of Rainwater Resources and Its Experiment

The utilization of unconventional water resources, especially the rainwater resources, has already been an important way of solving the lack of water resources. Based on the studies of the utilization of rainwater resources at home and abroad, the technology of rainwater utilization is investigated in this paper. Then the relationships between rainfall and collected rainfall, rainfall intensity and collected rainfall are analyzed through an experiment of the system of rainwater utilization. Furthermore, rainwater sample collected in a rain is analyzed after treatment according to related criteria. It's found that the relationships between collected rainfall and rainfall, collected rainfall and rainfall intensity are notlinear. The rainwater can be collected only when the rainfall is more than 20 mm or the average rainfall intensity is more than 0. 04 mm/min. The quality of the collected rainwater is better than the corresponding national standards, therefore it can be used as domestic miscellaneous water.
