Abstract: 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 running 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.

Key words: TNT wastewater, electrolysis-Fenton method, iron anode, COD removing rate
