摘要
本文采用一种新型的MIEX磁性离子交换树脂对某水厂原水进行预处理,考察了MIEX树脂用量与后续混凝工艺对原水的浊度、有机物、无机阴离子的去除效果。结果表明,MIEX技术可有效地去除原水中的有机物,对UV254和CODMn的去除率分别稳定在90%和59%。MIEX树脂对无机阴离子也有很好的去除效果,对SO24-的去除率一般为80%以上,NO3-为50%以上。但MIEX树脂对低浊水的去浊效果一般,同时MIEX预处理可以有效强化混凝沉淀对有机物的去除。
In this paper, a novel magnetic ion exchange resin （MIEX） was used to pre-treat the raw water in a water works. The removal performances of MIEX with different dosages for turbidity, organic and inorganic anion were studied. The results showed that by applying MIEX technology, organics could be removed efficiently; the removal rates for UV254 and CODMn were kept steadily at 90% and 59% ; MIEX could also remove inorganic anion with good efficiency, 80% and 50% or higher for SO42- and NO3- respectively. However its removal rate on low turbidity water was just so-so. Additionally by pretreatment using MIEX, the organics could be removed efficiently during the coagulation settlement process.
