A new process for the treatment of wasted liquid by use of the gelation method as a core technology

提出了一种利用胶体颗粒固定化处理废胶体悬浮液的新方法。将藻酸盐水溶液和胶体悬浮液的混合物添加到氯化钙水溶液中，得到海藻酸钙凝胶。凝胶悬浮液在重力作用下被排出，然后凝胶颗粒被机械地表达。在表达过程中，胶体颗粒留在凝胶中，所表达的液体是透明的。只要在胶体悬浮液中加入适当的物质，这种方法可以扩展到纳米胶体悬浮液、溶解物质和非水胶体悬浮液的处理。

A new method utilizing particle immobilization in gel is proposed for the treatment of wasted colloidal suspensions. A mixture of alginate aqueous solution and colloidal suspension is added to a calcium chloride aqueous solution, resulting in calcium alginate gels. The gel suspension is drained gravitationally, followed by mechanical expression of the gel particles. During the expression, the colloidal particles remain in the gels and the expressed liquid is clear. This method can be extended for the treatment of nanocolloidal suspensions, dissolved matters, and non-aqueous colloidal suspensions, provided that appropriate substances are added to the colloidal suspensions.
