铁氧体共沉淀法处理含Ni2+废水的研究

摘要

通过实验研究了铁氧体法处理含镍废水的工艺条件.结果表明,在pH=9.0、n(Fe<'2+>):n(Ni<'2+>)=2、温度为70℃的最佳条件下,镍的转化率可达99.0%以上,废水中的Ni<'2+>可从100 mg/L左右降至0.47 mg/L,达到排放标准.%The technological conditions for the treatment of Ni2+-containing wastewater by ferite process have been studied. When the best treating conditions are as follows: pH=9.0, n (Fe2+) :n (Ni2+) =2, and temperature=70 ℃, the conversion rate of Ni2+could be more than 99.0％ ,and the concentration of Ni２+ could be lowered from 100 mg/L to 0.47 mg/L, reaching the discharge standard.
