Research on treatment of 2,4-DCP wastewater by iron chips-activated carbon internal electrolysis

The treatment of 2,4-dichlorophenol wastewater by iron chips-activated carbon internal electrolysis is investigated in this paper. The influence of five factors(iron-carbon ratio, reaction time, temperature, pH, concentration of 2,4-dichlorophenol) on the results is discussed. The best condition for 2,4-DCP removal is: iron-carbon ratio is 5∶1,pH=2, reaction time is 90-120min. The result show that in this best condition the removal ratio of 2,4-DCP (initial concentration is 50 mg/l) reaches over 95%.
