活化沸石降低水硬度和铁锰含量的实验研究

Laboratorial Research on Decreasing Rigidity,Iron and Manganese in Water Disposal by Zeolite Activation

目的 通过不同的处理方法 ,提高沸石的吸附和交换的能力 ,观察对饮用水中硬度、铁和锰的处理效果 ,探索比较理想的沸石活化方法。方法 我们采取 4种不同方法处理沸石后 ,分别对水进行过滤实验 ,测定过滤前后水中总硬度、铁和锰含量的变化。结果 在一定过滤水量的前提下 ,过滤后水中的总硬度、铁和锰均与过滤前有明显的减少 ,与国家饮用水标准比较均能达到要求 (P <0 0 1 )。结论 沸石经过最佳的途径活化后 ,应用在水处理中 ,对去除水中硬度、铁和锰有很好的效果 。

Objective To improve adsorption and exchange ability of zeolite by different disposal methods and observe the decreasing effect of rigidity,iron and manganese,explore relative perfect method of zeolite activation. Methods The zeolite was disposed by four different methods,and then the change of rigidity,iron and manganese were determined by filtration experimentation. Results Under the condition of certain amount of water,the rigidity,iron and and manganese decrease obviously in filtrated water which meets the national standard of drinking water ( P <0 01).Conclusions It is highly effective on purification of water and has a wide range of application.
