利用小试实验研究了磁性离子交换树脂对水中硝酸盐的去除效能,并探讨了地下水中常见有机物及无机离子对其去除效能的影响.结果表明,磁性离子交换树脂对纯水中20mg/L的NO3--N的交换容量为55.91mg/mL,且去除速率较快,10min基本达到去除平衡；地下水中的腐殖酸类有机物对NO3--N的去除基本没有影响,而常见阴离子具有较明显的影响,其影响程度为SO42->CO32->Cl->HCO3-；针对徐州某水厂地下水的去除研究表明,通水倍数为500BV时磁性离子交换树脂对地下水中NO3--N的去除率约为50%左右.综上,磁性离子交换树脂可以作为去除地下水中的硝酸盐一种处理技术.

The groundwater nitrate removal efficiency and its influence factors which were common organic and inorganic ions in the groundwater were studied by underbrush experiment. The research results showed that the exchange capacity of magnetic ion exchange resin in prepared 20mg/L of nitrate nitrogen(NO3--N) solution was 55.91mg/mL, and the magnetic ion exchange resin removal rate was faster than other common resins, which could get equilibrium in 10min. Humic acid had an unconspicuous influence on nitrate removal by magnetic ion exchange resin. On the contrary, common inorganic anions had more obvious influence, and the influence degree was SO42->CO32->Cl->HCO3-. The research on groundwater of a Xuzhou waterworks showed that magnetic ion exchange resin in the groundwater could remove about 50%NO3--N when the water ratio got to 500BV. In conclusion, magnetic ion exchange resin could be a processing technology on nitrate removal in the groundwater.
