Abstract:

The technical feature and process of the biological contact oxidation technology can be used for treating tanning wastewater. The results indicate that the effluent quality can meet the requirements of the Second Grade of the Comprehensive Effluent Discharge Standard(GB 8978-1996). The running results show that the treatment efficiency of the technology is stable, the tolerable shock load range is wide, the combination of processes is reaso-nable and the treatment is promising.

Key words: tanning wastewater, biological contact oxidation technology, wastewater treatment
