摘　　要：粒状活性炭净水器是净化饮用水的经济实用的深度净化设备,自动反冲洗活性炭净水器在使用寿命和运行操作上均优于传统活性炭净水器。本文对自动反冲洗活性炭净水器处理上海某区的自来水进行实验,考察了自动反冲洗活性炭净水器在不同处理水量时对污染物的去除效率,实验发现:该净水器对CODMn、色度、浊度及余氯均有较好的处理效果;自动反冲洗装置可延长活性炭使用寿命,活性炭依靠过滤截留和吸附的共同作用去除水中的浊度,利用现场快速检测余氯浓度,可间接判断活性炭是否失效。Granular activated carbon（AC） filter is a economical and efficacious treatment device for potable water. Automatic back washing filter which has longer life period can be operated more conveniently than traditional one. The treatment of tap water in one district of Shanghai with automatic back washing filter was studied and introduced in this paper. The experiment results showed that the pollution removal efficiencies reduced with the increase of treated water quantity. The results also indicated that the AC filter was a effective device for removal of CODMn ,colour,turbidity and chlorine in water. The life period of activated carbon in automatic back washing filter was obviously extended thanks to automatic back washing.The turbidity was taken out of water by straining and adsorption on the activated carbon bed. The adsorption capacity of the AC filtes may be indirectly judged by determining residual chlorine concentration in the filtered water.
