铁阳极电解Fenton法处理TNT废水的试验研究

摘要

The major influencing factors of TNT wastewater treated by electrolysis-Fenton method ,for which iron is used as anode,have been researched. The effects of the concentration of H2O2,concentration of Na2SO4,pH,voltage and electrolysis time on the removing rates of TNT and COD are investigated. It is ascertained that the optimal run-ning parameters are as follows:H2O2 concentration is 180 mg/L,Na2SO4 concentration 500 mg/L,pH=7.0,voltage 7 V and electrolysis time 2 h. Under these conditions,the removing rates of TNT and COD are 97%and 65%respectively.%研究了以铁为阳极的电解Fenton法处理TNT废水时的主要影响因素：H2O2投加量、Na2SO4投加量、pH、电压、电解时间对TNT和COD去除率的影响，确定了其最佳运行参数：H2O2投加量180 mg/L，Na2SO4投加量500 mg/L， pH=7.0，电压7 V，电解时间2 h。在此条件下，TNT去除率可达97％，COD去除率可达65%。
