光催化NaH_2PO_2去除给水中溶解氧的研究

A Study of Removing Dissolved Oxygen in Feed water by photocatalysis of NaH_2PO_2

进行了在紫外光的催化下,NaH2PO2去除给水中溶解氧的研究,结果表明,NaH2PO2的用量,水温,光照时间和pH值对给水中溶解氧的去除有影响。NaH2PO2的用量为25.00mg/L、给水温度在60℃、给水pH值为8.0左右、紫外光照射时间为1min时,给水中溶解氧的去除率达98%。

The removal of dissolved oxygen in feed water with NaH2PO2 under the catalysis of ultraviolet was studied. The results showed that dosage of NaH2PO2, the temperature of water, the time of illumination and the pH value had effects on the removal of the dissolved oxygen in feed water. Under the conditions that the dosage of NaH2PO2 was 25.00 mg/L, the temperature of feed water was 60℃, the pH value of the feed water was about 8.0, and the time of illumination was 1 minute, the removal rate of dissolved oxygen in feed water reached 98%.
