摘要
2012年2～12月,对青草沙水库排水闸口的浮游藻类进行采样分析,共鉴定浮游藻类7个门,其中绿藻门和硅藻门种类数最多,为94种和68种,占总数的47%和34%;蓝藻门为26种,占13%;甲藻门5种,占2%;裸藻门5种,占2%;隐藻门3种,占1%;金藻门为最少,只有1种,占1%。结果表明全年藻类种类数、优势种均有明显的季节变化,夏秋季较利于藻类生长,并提出一些建议和措施来控制水库中的藻类繁殖。
Three supplementary disinfection methods for secondary water supply in Shanghai were investigated in this study. The parameters for each adopted technology were given by beneh-scale research of different disinfection methods. The UV disinfection was chosen as a demonstration which ean be a valuable trial for its application in secondary water supply in Shanghai.
