Abstract:

The advanced treatment of coking wastewater by three-dimensional fluid bed electrode technology has been studied and the technological parameters have been obtained. The results show that this reactor is practicable to be used for treating coking wastewater effectively. When the electrolysis time is 1 h， electrolysis voltage 10 V， aeration quantity 0.3 m³/h， pH=2， and the concentration of activated carbon 100 g/L， the removal rate of CODCr reaches over 65%.

Key words: three-dimensional fluid bed electrode, advanced treatment, coking wastewater
