| 摘 要： | 研究了2种提高膨润土絮凝去除铜绿微囊藻效果的方法--在膨润土中引入聚合氯化铝(PAC)及利用壳聚糖将膨润土进行改性处理.实验结果表明,这2种方法均在投加量较低时就能产生明显的去除效果,而相同用量的膨润土则几乎没有去处能力.当膨润土投加量为40 mg/L,PAC投加量为10 mg/L时,两者复合除藻效果最好,藻悬液的浊度...

| Abstract: | Two methods improving the capability of bentonite of flocculating and removing algal cells of microcystis aeruginosa are studied in this paper.Bentonite compounded with polymeric aluminum chloride(PAC) or modified with chitosan both has obvious removal effect at a low dosage,while the pure bentonite almost has no effect at the same dosage.The removal rates of turbidity and chlorophyll-a can reach 93.8% and 95.1% respectively and it is the best when the bentonite and PAC dosage is 40 mg/L and 10 mg/L respect... |
