Abstract:

An experimental study on vehicle-washing wastewater has been conducted by three-phase/threedimensional electrode method. Corresponding technological parameters for various influential factors which affect the treatment efficiency， including voltage， electrolysis time， airflow， and pH， are obtained. The results show that when the voltage is 25 V， the electrolysis time 30 min，the airflow 3 L/min，and the removal rate of COD over 85%.
