摘　　要：以日本岐阜市长良川河水为研究对象,探讨生物活性炭(BAC)小柱和粒状活性炭(GAC)小柱去除天然有机物(NOM)的效果。结果表明,BAC可以去除水中的NOM,处理效果优于GAC吸附。BAC对水质变化有一定的抵抗力,可以延长活性炭使用寿命。试验过程中,空床接触时间为39.2 min,DOC的平均去除率为51.1%,UV260的平均去除率为84.7%。Using water of Nagara River in Gifu Japan, which contains low content of NOM, as the water for study, the removal efficiency for NOM by a biological activated carbon （BAC） column and a granular activated carbon （GAC） column was studied through measurement of the lumped quality indices of total dissolved organic carbon （DOC） and ultraviolet absorbance at 260 nm （UV260）. The results showed that NOM could be removed by BAC and its removal was higher than that by GAC. BAC demonstrated higher capability to deal with water quality fluctuation and was capable of extending the life of activated carbon. For an empty bed contact time of 39.2 min, the average removal of DOC and UV~ was 51.1% and 84.7%, respectively.
