  • 摘要: 采用不同方法对天然沸石改性,并用改性后沸石进行了静态和动态除铁锰实验。结果表明,采用NaCl、HCl、微波方法对沸石改性,以NaCl改性效果最好。经浓度为25%的NaCl改性后的沸石铁去除率提高了13.81%,锰去除率提高了26.4%。沸石改性可以同步提高其除铁、除锰效果,且除锰效果提高更多。铁或锰的存在都能使对方单一被沸石吸附效果下降。用沸石滤柱处理高铁锰地下水,在停留时间1.0 h时,铁最高去除率为62.3%,锰最高去除率为58.3%。
    Abstract: Modified zeolite was used to treat groundwater with high iron and manganese, NaCl, HCl and microwave were used to strengthen its absorption. The experimental results showed that zeolite modified by NaCl was the best to remove iron and manganese. When zeolite modified by NaCl of 25%, the removal rate of iron increased 13.81%, manganese removal rate increased 26.4%. The amount of zeolite adsorption of manganese and iron synchronous enhanced. The presence of iron or manganese can make the other's adsorption capacity decreased. Deal with zeolite filter column, with residence time of 1.0 h, iron removal efficiency is 62.3%, and manganese removal efficiency is 58.3%.
