%X Advanced treatment of coking wastewater by iron-carbon micro-electrolysis process with aeration was studied. It was found the COD removal efficiency reached 30% -40% with 10 g/L active carbon 30 g/L iron material and 200 mg/L sodium chloride after 240 min reaction. Low pH condition improved the COD removal efficiency. The micro-electrolysis process can remove the refractory organic compounds. The dominant contaminants in the effluent are ester and alkyl compounds, which have the low molecular weight less than 2000 Da. The process enhanced the biodegradability of the effluent evidently, for BOD5/COD ratio increased from 0.08 to 0. 53. Therefore, iron-carbon micro-electrolysis process is an effective means for advanced treatment of coking wastewater.
