摘　　要：采用芬顿法对某环保公司TFT-LCD有机废水进行预处理,通过设置单因素实验,研究了初始pH值、双氧水加入量、硫酸亚铁加入量以及反应时间四个因素的影响。在反应初始pH值为3、H2O2加入量为50 mL、FeSO_(4)·7H_(2)O加入量为12 g、反应时间为2 h的条件下,COD去除率可达到48.58%。该研究数据可为TFT-LCD行业有机废水的预处理提供数据依据。Fenton was used to pretreat TFT-LCD organic wastewater from an environmental protection company.Through setting up a single factor experiment,the effects of four factors including initial pH value,hydrogen peroxide addition,ferrous sulfate addition and reaction time were studied.When the initial pH of the reaction is 3,the amount of H2O2 is 50 mL,the amount of FeSO_(4)·7H_(2)O is 12 g,and the reaction time is 2 h,the COD removal rate can reach 48.58%.The research data can provide data basis for the pretreatment of organic wastewater in TFT-LCD industry.
