| 摘 要： | 在研究粘土颗粒与赤潮生物絮凝作用的基础上，建立了粘土表面改性对其絮凝作用影响的理论模型，认为改变粘土颗粒的表面性质提高其去除赤潮生物能力的主要途径，提出在粘土中引入ＰＡＣＳ（聚羟基氯化铝）的改性方法。结果表明，对于微型原甲藻（Ｐｒｏｒｏ－ｃｅｎｔｒｕｍ ｍｉｎｉｍｕｎ）体系，粘土中引入微量ＰＡＣＳ后，其去除率达９０％以上的高岭土用量由原来的２ｇ／Ｌ降至０．１ｇ／Ｌ，去除效率提高近２０倍。考察了ＰＡ

| Abstract: | A theoretical model based on study on the coagulation of red tide organismswith clays shows that the surface modification of clays affects the coagulation andis the main way to improve the capability for clays to remove red tide organisms.The improved method of adding PACS (polyhydroxy aluminum chloride) in clays isfirst proposed. The results show that the concentration of kaoline at which the removal ratio of Prorocentrum minimum is more than 90% decreases to 0.1g/L from2g/L, and that removal efficiency increasing almost 20 times, due to addition ofPACS. The effects of PACS molecular weight on the improvement are also examined.It was found that PACS prepared under different conditions are different in the improvement. PACS with the optimum performance was obtained. |
