| 摘 要： | 实验研究了不同反应条件的铁沉降效率及锌、镉损失率。结果表明,氧气做氧化剂pH为3.0~3.5时,反应7 h后,铁沉降效率不高,仅达到34%,锌、镉损失率随反应时间的增加而增加。铁沉降效率随pH及温度的升高而增大,SEM和XRD分析表明,pH为3.0时的沉铁渣中主要成分是针铁矿。

| Abstract: | Efficiency of iron precipitation and zinc, cadmium loss were studied in different reactive conditions. The results showed that iron precipitation rate was not high and reached only 34 % when oxygen was used as oxidant and pH is between 3.0 and 3.5 after 7 h＇ reaction. The iron precipitation rate and zinc, cadmium loss increased with the increasing of pH and temperature. SEM and XRD analysis presented that the main content of precipitates are goethite when pH is 3.0. |
