| 摘 要： | 为了考察混凝沉淀工艺的除藻性能在不同藻类优势期内的变化,将试验过程分为绿藻优势期和蓝藻优势期两个阶段,进行进水藻类群落结构特征及其变化对混凝沉淀除藻效能的影响研究.结果表明,混凝沉淀在绿藻优势期和蓝藻优势期的除藻效率分别为68.3%和40.4%,且各种藻类的去除效能并无明显的相互影响.蓝藻优势期的藻类去除率大大低于绿藻优势期,其根本原因在于占优势地位的微囊藻的生理生态特征.因此,把水中的所有藻类笼统地作为一个去除对象是不适宜的,应分析水中藻类群落结构特征,并根据特定原水中的优势藻种类进行针对性的除藻方案研究.

| Abstract: | To study the removal characteristics of algae during different predominant algae periods,the experiment process was divided into two stages,which includes chlorella predominant stage and cyanobacteria predominant stage,to study the algae community structure characteristics and the influence of their changes on the algae removal efficiency.The results showed that the algae removal efficiency in chlorella and cyanobacteria predominant stages was 68.3% and 40.4% respectively,and removal efficiency of different... |
