| 摘 要： | 研究了壳聚糖与纳米钛、纳米铁或妫水湖沉积物絮凝剂絮凝沉降水华蓝藻的效果。结果表明：在壳聚糖浓度为3 mg/L情况下，与妫水湖沉积物和纳米钛相比，纳米铁絮凝沉降蓝藻细胞的效果最好，在10 min内可以絮凝沉降79.5%以上的水华蓝藻细胞。进一步研究显示，在pH值为5～9的范围内，随着pH值的降低，絮凝沉降藻细胞的效率逐渐提高，pH值为5时10 min内可以絮凝去除89.6%以上的水华蓝藻细胞，具有重要的研究价值与应用价值。

| Abstract: | The flocculation of cyanobacteria by chitosan-nano-Ti,nano-Fe or sediment collected from Guishui Lake were investigated in this paper.It was found that,compared with the sediment and nano-Ti,nano-Fe was showed to be a better flocculating agent for the flocculation of cyanobacterial cells,and more than 79.5% of cyanobacterial cells were flocculated in 10 min.The effect of pH on the flocculation of cyanobacterial cells was further studied.It was indicated that the flocculation efficiency of cyanobacterial cel... |
