摘　　要：硼是超纯水水质的关键指标之一,可通过除硼树脂去除,但市场上除硼树脂主要被国外企业垄断,国产树脂应用少,运行参数和稳定性不明确,市场推广难度大。通过除硼树脂静态吸附试验和连续流中试,开展对典型国产除硼树脂的性能评价和项目应用研究。根据吸附容量、有机碳溶出、再生稳定性、长期运行稳定性、采购成本及货源稳定性等多元评价指标,筛选出性能优异的国产除硼树脂,硼吸附量可达5.1 g/L,TOC溶出量低至3.01μg/L,经过10次再生后除硼吸附量为新树脂的97.84%,在中试线实现了连续9个月高标准除硼和稳定运行,产水硼质量浓度稳定低于10 ng/L。将筛选出的国产树脂A及运行参数应用于实际工程中,实现了超纯水系统稳定除硼至50 ng/L以下,并长效稳定运行。Boron is one of the key indicators of ultra-pure water quality,which can be removed by boron removal resin,while the resin market is occupied by foreign enterprises.Domestic resin is rarely applied because of unclear operating parameters and instability,which increases the difficulty of promotion.In this study,static adsorption and continuous flow pilot tests of boron removal resin were used to evaluate the performance and project application of typical domestic boron removal resin.According to the multiple evaluation indexes such as adsorption capacity,or-ganic carbon dissolution,regeneration stability,long-term operation stability,procurement cost and supply stability,domestic boron removal resin with excellent performance was selected.The boron adsorption capacity of the domes-tic boron removal resin could reach 5.1 g/L,TOC dissolution could be as low as 3.01µg/L,and the boron removal adsorption capacity after 10 times consecutive regeneration was 97.84%of the new resin.High standard boron re-moval and stable operation were achieved in the continuous pilot line for 9 months,the boron mass concentration of effluent was stably below 10 ng/L.The selected domestic boron removal resin and operating parameters were applied to practical projects,and stable boron removal was achieved to less than 50 ng/L with long-term stable operation.
