水处理工艺去除饮用水中藻毒素的功效

The Efficiency of Water Treatment Procedures on Removal of Cyanobacterial Toxins in Drinking Water

为人类提供安全的饮用水是公共卫生最重要的问题之一。由于有毒藻类繁殖而引起的水体藻毒素污染越来越严重,藻毒素对水体的污染及其对健康的危害性日益受到人们的关注。如何将饮用水中藻毒素的水平降至可接受的水平以下是饮用水的供应者们面临的一个重要问题。常规水处理工艺较难将其有效去除。活性炭吸附、光催化氧化、臭氧化、氯化、膜滤和生物降解等方法均能较好地去除毒素,但在实际应用中各自存在着一定的局限性。

To provide the human being with safe drinking water is one of the most important issues in public health. In response to the more and more serious pollution of algal toxins, growing concern has been attached to the water bodies contaminated with algal toxins and the effects posed on human health. Drinking water suppliers are confronted with the important problem of how to remove the toxins to the acceptable levels. Conventional water treatment procedures are not efficient in removing toxins. Activated carbon adsorption, membrane filtration, photocatalic process, ozonation and chlorination are effective in removing cyanobacterial toxins, but each has its limitation.
