摘　　要：新的电化学除氧方法是让含溶解氧的自来水流经三维电极,阴极室填充001X7H型离子交换树脂和喷铜砂的不同比例混合物,通过实验得出树脂和填料的体积混合比为1∶1时,有较好的除氧效果;将不同反离子的离子交换树脂进行实验,001X7H型树脂的除氧效果最好,同时得出自来水电化学除氧的槽电压为2.1V;在此电压下,出口氧含量低于0.10mg/L的最大流量为7L/h。A new electrochemical method of dissolved oxygen removal has been developed by w hich tap water flows through a cell of three-dimensional electrode,the cathode of which is made of 001x7H-type ion-exchange resins mixed with spray copper- sand by differen t volume ratio to act as oxygen remover from the tap water.The results show that when the ratio of the ion-exchange resin to the spray copper-scond is 1 to 1,the oxygen removal efficiency is the best;In the resins containing diffe rent counter ions,H-type resins shows the best effectiveness,and it is also fo und that the optimal cell voltage of electrochemical de -oxygenation is 2 1 V,outlet oxygen content is 0 04 mg/L.When the cell voltage is 2 1 V,the outl et oxygen content is lower than 0 10 mg/L for the flow high up to 7 L/h.
