经济的快速发展加速了自然界氮素循环速率,大量湖泊和水库呈现富营养化状态。含有大量微囊藻毒素的蓝藻水华,给人们造成巨大的经济损失和健康危害。本文在参考大量文献的基础上,简要讨论了富营养化水体中微囊藻的优势生长机制,并主要从预防和控制两方面阐述了富营养化水体中蓝藻的治理途径。蓝藻水华就像是湖泊的慢性疾病一样,完全“治愈”是非常困难的,但可以预防和控制相结合,把其危害减低到最小。
Methods for prevention of mass development of cyanobacteria in continental water bodies and industrial water supply systems were reviewed. The physical, chemical, and biological methods for prevention of cyanobacterium development in water bodies and water supply systems are consid- ered; examples of successful inhibition of cyanobacterium growth in laboratory experiments are demonstrated. The scientific problems are outlined that are to be solved for perfecting techniques for prevention of cyanobacteria mass development in open water bodies and in closed water supply systems.
