从铁锰含量高的地下水制取生活饮用水的研究──CHZ-02型净化水装置的研制及应用

STUDY ON PREPARING DRINKING WATER FROM A LARGE AMOUNT OF IRON- AND MANGANESE^BEARING UNDERGROUND WATER DEVELOPMENT AND APPLICATION FOR CHZ-02 TYPE WATER PURIFYING DEVICE

根据山东平原县地下水中铁锰含量高的特点，用天然锰砂可以从地下水中吸滤去除铁、锰等有害元素，而且可长期使用又无需专门的再生处理。再配以活性炭吸附，离子交换，电渗析等净化、分离设备，即可将不符合卫生标准的地下水制成高质量的生活饮用水。CHZ－02型净化水装置正是基于这些技术研制而成的，运行一年多，其操作及处理效果均良好。

Natural pyrolusite sand was developed to eliminate the hurtful ions such as iron,manganese etc. from underground water according to the properties of a large amount of iron- andmanganese-bearing underground water in Pingyuan county of Shandong province. The pyrolusite can be used for a long time and no special regeneration is demanded. Combining it withactive carbon adsorption,ion-exchange and electro-dialysis separation units,the undergroundWater which is inconsistent with hygienic standard can be purified to high quality drinkingwater. The CHZ-02 type water purifying device was developed on account of these techniques. It shows good performance by more than one year of operation.
