摘要：

实验研究了常温中和铁氧体法处理低浓度镍盐生产废水的工艺条件。试验结果表明，以Na₂CO₃为pH调节剂，在pH8.5～9.0,室温,n(Fe³⁺)：n(Fe²⁺)=1.5∶1,n(Fe²⁺)∶n(Ni²⁺)=12∶1，搅拌时间为15min的条件下，处理效果最佳。镍的去除率达到98%以上，处理后的废水中Ni²⁺质量浓度达到0.20mg/L以下，达到国家排放标准。

Abstract:

The experiment has studied and determined the best treatment conditions of low concentration nickel salt wastewater, n( Fe³⁺) ∶n( Fe²⁺) =1.5∶1, n( Fe²⁺) ∶n(Ni²⁺) =12∶1, roomtemperature, pH 8.5-9.0, Na₂CO₃ is the pH regulator.The stirring time is 15 min. The Ni²⁺ removal efficency is above 98%. The concentration of Ni²⁺ in treated water is below0.20 mg/L.It meets with the discharge standard.
