正交法探索皂素废水中Fe^(2+)的变化

The orthogonal method to explore the change of saponin wastewater Fe^(2+)

以黄姜皂素废水为原料,以Fe^(2+)的含量为指标,研究进水pH、过氧化氢投加量、反应时间、温度及过氧化氢投加方式对黄姜皂素废水处理效果的影响。结果表明,反应的最佳条件为:进水pH为3. 0,过氧化氢投加量8%,反应时间2 h,温度30℃,过氧化氢投加方式为分三次投加。此时,废水中Fe^(2+)的含量达最少值0. 541 6 mg/L。

The Dioscorea Zingiberensis C.H.Wright diosgenin wastewater was used as raw material,and used the mass fraction of Fe 2+as evaluation index.The effect of treatment technology of Dioscorea Zingiberensis C.H.Wright diosgenin wastewater were investigatad by influent pH value,the hydrogen peroxide dosage,reaction time,temperature and the hydrogen peroxide dosing method systematically.The result shows that the optimum condition as follows:the mass fraction of Fe 2+should be at least 0.541 6 mg/L,when the influent pH value was 3.0,the hydrogen peroxide dosage was 8%,reaction time was 2 h,temperature was 30℃and the hydrogen peroxide dosing method for three times dosing.
