Abstract:

A new method has been established for decoloring ofhigh colority dyeing wastewater with oxide-flocculation reactor( OFR) technique.The mechanism of dye and other contaminants removal is actually the oxidation of hydroxyl radical (·O H).Various factors whether physical or chemical: cellvoltage, main electrode distance, testing solution,pH value, air flow rate, treating time etc, which affected the decoloring rate have been studied.The results of contaminants removal in dyeing wastewater for colority> 10000 under the optical testing condition were very good: decoloring rate> 99%, COD_Cr removal rate> 75%.
