Lack of fresh water is a concern for the future of human because commonly used technologies for producing drinking water from saline water, such as reverse osmosis, electrolysis has been expensive to produce and or, like flash techniques and multi‐stage distillation, are dependent on the fossil energies. In this study, the shallow solar basin has been proposed to simply collect and store solar thermal energy to produce drinking water from salt water. Also, the use of nano particles increases the rate of evaporation in the shallow solar basin. In this way, the experiments have been conducted to optimize the efficient factors in the operation of a shallow solar basin equipped with a nano plate at the bottom of the pool. This shallow solar basin is concentrated in saline water and produces distilled water as the main processing stage for distillation of zero discharge. In this way, concentrated saline water prepares the inflow for evaporation units. The main parameters such as insolation rate, values of produced drinkable water and average temperature of shallow solar basin layers are investigated in this study. The comparison between evaporation rate values in a shallow solar basin equipped with nano plates and conventional solar basin shows an increase of 20%. The results show better performance of the proposed shallow solar basin than the simple shallow solar basin. The test results show the maximum and minimum evaporation rates of 5 and 2 L in June and January 2019, respectively.

在封闭的浅层太阳盆中从微咸废水生产淡水中使用纳米底的实践研究

淡水的缺乏是人类未来的担忧,因为从盐水中生产饮用水的常用技术(例如反渗透,电解生产成本很高),或者像闪蒸技术和多级蒸馏一样依赖于化石的能量。在这项研究中,提出了浅层太阳盆,以简单地收集和存储太阳能以从盐水中产生饮用水。而且,纳米颗粒的使用增加了浅太阳盆地中的蒸发速率。以这种方式,已经进行了实验以优化在池的底部配备有纳米板的浅太阳能水池的运行中的效率因素。这个浅水太阳盆集中在盐水中,并产生蒸馏水,作为零排放蒸馏的主要处理阶段。通过这种方式,浓盐水将流入的水准备用于蒸发装置。研究了日晒率,饮用水量和浅层太阳盆层平均温度等主要参数。在装有纳米板的浅型太阳盆和常规的太阳盆中,蒸发速率值的比较显示增加了20%。结果表明,所提出的浅层太阳盆比简单浅层太阳盆具有更好的性能。测试结果显示,2019年6月和2019年1月的最大和最小蒸发速率分别为5 L和2 L. 浓盐水准备流入蒸发单元。研究了日晒率,饮用水量和浅层太阳盆层平均温度等主要参数。在装有纳米板的浅型太阳盆和常规的太阳盆中,蒸发速率值的比较显示增加了20%。结果表明,所提出的浅层太阳盆比简单浅层太阳盆具有更好的性能。测试结果显示,2019年6月和2019年1月的最大和最小蒸发速率分别为5 L和2 L. 浓盐水准备流入蒸发单元。研究了日晒率,饮用水量和浅层太阳盆层平均温度等主要参数。在装有纳米板的浅型太阳盆和常规的太阳盆中,蒸发速率值的比较显示增加了20%。结果表明,所提出的浅层太阳盆比简单浅层太阳盆具有更好的性能。测试结果显示,2019年6月和2019年1月的最大和最小蒸发速率分别为5 L和2 L. 在装有纳米板的浅型太阳盆和常规的太阳盆中,蒸发速率值的比较显示增加了20%。结果表明,所提出的浅层太阳盆比简单浅层太阳盆具有更好的性能。测试结果显示,2019年6月和2019年1月的最大和最小蒸发速率分别为5 L和2 L. 在装有纳米板的浅型太阳盆和常规的太阳盆中,蒸发速率值的比较显示增加了20%。结果表明,所提出的浅层太阳盆比简单浅层太阳盆具有更好的性能。测试结果显示,2019年6月和2019年1月的最大和最小蒸发速率分别为5 L和2 L.
