摘要
选用苯酚废水为模拟实验废水,对芬顿试剂对其化学需氧量的去除率展开探究,通过展开单因素实验,对这一实验效果受反应时间、pH值、Fe^2+量及过氧化氢投加量的影响展开相关研究。结果表明:每升溶液中投加FeSO4·7H2O2 g,H2O24 mL,反应时间为25 min,pH值为4,COD去除率最高,这一项方法不用过多花费资金,且快捷方便,发展前景十分良好。
Phenol wastewater was selected as the simulated experimental wastewater,and the removal rate of fenton reagent on its chemical oxygen demand was investigated.A single-factor experiment was conducted to investigate the effect of this experiment on reaction time,pH value,Fe^2+and hydrogen peroxide addition.The results show that FeSO42 g/L,H2O26 mL/L,reaction time of 25 min and pH of 4 are added,and COD is the highest removal rate.This method does not cost too much money,and is fast and convenient,with very good development prospects.
