• 摘要：用比浊法研究了小球藻与高岭土在实验条件下的凝聚沉降行为。结果表明,小球藻与高岭土的凝聚沉降是受颗粒表面理化作用力控制的过程。环境条件通过改变颗粒间的理化作用,在不同程度上促进或抑制颗粒凝聚沉降。根据颗粒凝聚沉降的特点,可将粘土用于水污染治理。

• Abstract：Aggregation and sinking behavior of C. vulgaris with Kaolin was studied by means of turbidity colorimetric analysis. The results indicated that the aggregation and sinking of C. vulgaris with Kaolin was controlled by the surface properties of the suspended particles. The surface properties were different under various environmental conditions, the aggregation and sinking processes were either enhanced or reduced consequently.

• Key words：Chlorella vulgaris  Kaolin  aggregation  surface property 
