Abstract

The treatment of coal chemical wastewater by the two-stage anaerobic process was studied in this paper. The results showed that the removal efficiency of chemical oxygen demand (COD), total phenols (TP), and volatile phenol (VP) could reach 53.9%, 52.6%, 84.9%, respectively, which was significantly better than the single-stage anaerobic unit. The division of each unit was different in the two-stage anaerobic process. The high removal of the easily degradable organic matter and the conversion of the volatile phenol compounds were achieved in the first stage anaerobic unit. The second stage anaerobic unit focused on the transformation of phenolic pollutants and ensured the stability and efficiency in the system. The two-stage anaerobic process offered an effective way for the treatment of coal-chemical wastewater.
