摘要
本研究结果表明,不同的藻类和不同的粘土颗粒均使藻类与粘土颗粒的凝聚沉降发生变化。结果还表明,溶液中[Cu^(2+)]浓度超过10^(-5)mol后,加快了小球藻与高龄土的凝聚沉降。使80％以上的小球藻和高岭土在不到10min内即凝聚沉降。在最后结合实验结果讨论了利用藻类与粘土的凝聚沉降治理水体污染。
The results indicated that,different algae and clay particles differentiated their aggregation and sinking behavior. The results also showed that,when the concentration of [Cu2+] solution exceeded 10-5mol,the aggregation and sinking of C. vulgaris with Kaolin was accelerated and more than 80% of the alga and clay finished this process in less than 10 minutes. Using the experimental results,the paper discussed pollution control of water bodies by aggregation and sinking behavior of algae and clay particles.
