摘　　要：上向流活性炭吸附池一般前置于砂滤池,相比以除浊为目的的下向流生物活性炭池,主要去除氨氮和有机物等。该工艺炭床处于流化状态,水头损失小,用地节省,反冲洗周期长,微生物安全性高,对有机物、氨氮和消毒副产物前驱体具有更强的吸附性能,是实现优质市政自来水供给的关键水处理技术。研究了近年来上向流活性炭吸附池在国内给水厂的应用,跟踪了多座成熟水厂的运行和设计经验,并对该工艺的发展趋势开展了探讨与展望,为全面实现高品质供水做好技术储备和市场推广。The up-flow BAC adsorption tank is generally placed in front of the sand filter.Compared with the traditional down-flow BAC tank,it is not for the purpose of turbidity removal,but mainly for the removal of ammonia nitrogen and organic matter.The carbon bed of this process is in a fluidized state,with smaller head loss,less land occupation,longer backwashing cycle,higher microbial safety,and stronger adsorption performance for organic matter,ammonia nitrogen and disinfection by-product precursors.Therefore,it is to be the key technology to realize high-quality municipal tap water.The paper studies the application of up-flow BAC adsorption tank in domestic water supply plants in recent years,tracks the operation and design experience of many mature water plants,and discusses and prospects the development trend of this process,to make technical reserves and market promotion for the full realization of high-quality potable water supply.
