常温下小直径的水珠表面水分子趋向于向空气中蒸发,而水平面则蒸发速率较低,对与其表面接触的空气中物质具有表面粘附效应。研究了水表面对空气中几种主要有害物质的粘附与沉降到水中的净化作用。建立了一个产生大面积水表面的装置,实验结果表明,该装置能够高效的将空气中的甲醛、氨气和PM2.5颗粒等有害物质攫取和沉降到水中,去除率均能达到90%以上。此净化方法不仅具有简单、成本低、空气净化效果好的特点,而且沉降到水中的有害物质容易作为废水进行无害化利用。
Water molecules at the surface of droplets of small diameter at room temperature tend to evaporate into the air, whereas water evaporates at a lower level and has a surface-adhering effect on the airborne material in contact with its surface. The adhesion of water surface to several main harmful substances in the air and the purification effect of sedimentation into water were studied. A device for producing a large area of water surface was established. The experimental results show that the device can effectively remove and settle harmful substances such as formaldehyde, ammonia and PM2.5 in the air to 90% . This purification method is not only simple, low cost, good air purification effect, and the sediment into the water of harmful substances as harmless to use as waste water.
