【Abstract】 The treatment of simulated wastewater containing chromium with the minute corrosive cell of iron filings_activated carbon was studied in this paper. The best conditions for the treatment of simulated wastewater of containing chromium were found. The results showed that the chromium removing rate in wastewater is over 99%, remaining concentration is less than 0.4 mg/L and lower than the national drain off standard (0.5 wastewater). The method has the advantages of simplicity,low cost and good removal effect.更多还原
