湖泊蓝藻水华治理技术研究进展

Research Progress on Treatment Technology of Cyanobacterial Bloom in Lakes

我国水体富营养化形势严峻,蓝藻水华频发,如何控制蓝藻水华一直是我国水治理的重难点之一。蓝藻水华治理目前主要分为物理控藻方法、化学控藻方法和生物控藻方法三大类:物理控藻法清洁无污染,能消减水体污染物但设备要求高,作业时间长费用高;传统化学控藻法见效快,但可能会引起二次污染;生物控藻法持续时间长,但见效慢或不易控制。对三类方法的作用原理、优缺点等进行了归纳总结,并展望了多方法组合、污染源削减和抑藻除藻并举的藻类治理技术新方向。

The situation of water eutrophication in China is severe, and cyanobacteria bloom occurs frequently. How to control cyanobacteria bloom has always been one of the key and difficult problems in water treatment in China. At present, the control of cyanobacteria bloom is mainly divided into three categories: physical algae control methods, chemical algae control methods and biological algae control methods. The physical algae control method is clean and pollution-free, which can bring out water pollutants. The equipment requirements are high;the time is long and the cost is high;The traditional chemical algae control method has a quick effect, but may cause secondary pollution;Biological algal control method lasts for a long time, but it is slow to take effect or difficult to control. This paper summarized the principles, advantages and disadvantages of the three methods, and looked forward to the new direction of algae treatment technology that combines multiple methods, reduces pollution sources and simultaneously suppresses and removes algae.
