摘要：

The effectiveness of electrochemical ozone and Integrated electrochemical-ozone processes on industrial wastewater was evaluated Electrochemical under optimal conditions of pH 7 and 40 mA cm(-2) of current density reduced the chemical oxygen demand (COD) by 43% and the biochemical oxygen demand (BOD5) by 42% Ozone treatment reduced both COD and BOD5 by 60% Integration of the two processes at pH 7 and 20 mA cm(-2) of current density greatly improved the reduction of COD (84%) BOD5 (79%) color (95%) turbidity (96%) and total coliforms (99%) Thus the integrated electrochemical-ozone process noticeably improves wastewater quality Finally the sludge produced during Integrated electrochemical-ozone process was quantified and the morphology was evaluated by scanning electron microscopy (SEM) and energy dispersive X-iay analysis (EDX) (C) 2010 Elsevier B V All lights reserved
