This paper studies the influencing factors such as microwave processing time,microwave power,FeSO4 dosing amount,H2 O2 dosing amount,H2 O2 dosing times and pH value during coking wastewater treatment by Microwave - Fenton oxidation. The optimum process conditions are deter-mined by the experiment:pH value of wastewater:3,FeSO4 dosing amount:300mg/ L,H2 O2 total do-sing amount of H2 O2:900mg/ L,H2 O2 dosing times:3,microwave power:500W,temperature:50℃ , reaction time:30min. the removal rate of turbidity,chroma and COD are 97. 59% , 95. 62% and 86. 21% respectively. The wastewater after treatment is clear,and the remaining COD is 50. 34mg / L. The turbidity,chroma and COD meet the requirement of industrial recirculating water standard.
