| 摘 要： | 活性氧化铝的除砷机理以吸附为主,其除As~(5+)的效率非常显著地高于As~(3+).水中As~(3+)用氯氧化后的去除率和As~(5+)相同.含砷0.75mg/L左右的原水将pH调至6.0～6.5的条件下,除砷容量为1.4～2.0mg/g Al_2O_3,处理1m~3水的化学品费用为0.221元.1m~3 Al_2O_3每个周期可处理水1700m~3以上.

| Abstract: | Experimental results indicate that absorption is the factor in the mechanism of arsenic removal by activate alumina.Its removal efficiency for As~(+5) is significantly higher than that of As~(+3). The efficiency of As~(+3) removal is similar to As~(+5),after As~(+3) is oxidated by chlorine.The arsenic removal capacity reaches to 1.4-2.0mgAs~(+5)/gAl_2O_3, when the pH of raw water (containing 0.75mg/L As) is adjusted to the range of 6.0-6.5.The cost of chemicals used is RMB 0.221/m~3 of treated water. For a treatment cycle, the yield of treated water for 1m~3 of filter bed is at least 1700m~3. |
