Abstract: The wastewater from electrolysis-Zn factory was studied,and was treated by iron-carbon micro-electrolysis reactor.The effects of time,pH value,DO and the dosage of iron-carbon were investigated on the removing rate of Cd,Pb and Zn in the wastewater.The results show that the iron-carbon micro-electrolysis process can be effectively used for the treatment of heavy metal wastewater on the suitable conditions:pH value 3~5,staying reaction time 30 min,DO 5 mg/L and the dosage of iron-carbon 50 g/L.On the best condition,the removal rates of Cd,Pb and Zn reached 96.5%,91.1%,72.6% respectively.

Key words: iron-carbon micro-electrolysis, heavy metal, wastewater
