电凝聚除氟条件的研究

EXPERIMETAL STUDIES ON FACTORS OF FLUORINE ION DISPOSAL USING ELECTROCOAGULATION METHOD

本文对羟基铝吸附剂的三种基本作用原理作了探讨。认为电凝聚除氟是在酸性条件下,依靠静电吸附和离子交换吸附的双重作用达到的。通过大量的实验数据分析和讨论了电凝聚除氟时pH,水温、其它离子等影响因素和控制条件,并提出了以铝氟比作为各种耗铝除氟法和不同电凝聚装置优劣的基本衡量标准。

In this paper the basic principles of hydroxyl aluminium adsorbent was used to explain the process of fluorine ion disposal by electrocoagulation method. The static electricity adsorption and the ion exchange adsorption for fluorine ion were achieved in the acidity solution. The large number experimetal data were analysed and the influence of the pH the temperature of solution and the other ions expect the fluorine ion for electrocoagulation were discussed. The author also advanced a basic measurement criterion that can compare the differant fluorine ion disposal methods expending aluminium.
