摘要
藻类是江河、湖泊、水库和海湾等任何水生生态系统的天然组成成分,然而过量繁殖的藻类对水厂原水的污染会影响出水水质。面对日益频繁的水华暴发事件,有必要进一步开展水厂除藻方法的研究。文中介绍了一些水厂除藻技术,如强化混凝法、预氧化法、气浮法、超声法、高级氧化法和电化学法,分析了各工艺的原理及优缺点。
Algae are the natural constituent components of any aquatic ecosystem, such as rivers, lakes, reservoirs, and bays. However, the pollution of over-propagating algae to water sources can affect effluent quality. Faced with the increasingly frequent outbreak of water bloom events, it is necessary to furtherly develop the method for algae removal in water treatment plant. Some algae removal technologies, such as enhanced coagulation, preoxidation, floatation, ultrasonic, advanced oxidation, electrochemical method are introduced, and the principle, advantages and disadvantages of each process are also analyzed.
