| 摘 要： | 实验采用壳聚糖和聚合氯化铝改性高岭土,进行以铜绿微囊藻为优势种的水华蓝藻去除的比较研究,研究采用动力学手段,通过去除效率的比较,得到线性方程:壳聚糖改性高岭土投加量(y)与藻细胞浓度OD68(x)和叶绿素a含量(x)之间的关系分别为:y=0.0349x-0.0019、y=0.0524x-0.009;聚合氯化铝改性高岭土投加量(y)与藻细胞浓度OD68(x)和叶绿素a含量(x)之间的关系分别为:y=0.0351x+0.0065、y=0.0676x-0.0059,壳聚糖改性粘土除藻的最适pH范围为5-8,聚合氯化铝改性粘土除藻的最适pH范围为5-9,pH范围相对较宽,电子传递速率分析表明壳聚糖改性粘土处理后1个月内藻趋于死亡,聚合氧化铝改性牯土处理过的藻,一周内藻开始黄化,衰老. |

| Abstract: | Microcystis waterbloom always occurs in colonial forms in natural waters. However, most laboratory studies on removal of Microcystis cells by various approaches were performed by using single-cell Microcystis strains. This study aimed to remove Microcystis aeruginosa, as the dominant species in Chinese waters, by Chitosan and Polymeric Aluminum Chloride (PAC) modified clays(Kaolin). Using colonial Microcystis aeruginosa strain HAB 657, the relationships between the quantity of the chitosan modified clays(y)... |
