Abstract

Abstract

In order to enhance the COD removal of petrochemical biochemical effluent, the removal effect of micro flocculation sand filtration and ozone catalytic oxidation on COD in petrochemical biochemical effluent was analyzed. The COD removal under different combination modes of ozone catalytic oxidation tower was compared. The lab-scale, pilot-scale and productive scale of catalytic ozonation were carried out. The ozonation tower with two stages, one-stage aeration and one-stage reflux (reflux ratio 100%) were recommended for its good performance. When the bio-treated petrochemical wastewater was 70~120 mg/L, micro flocculating sand filter effluent was 65~113 mg/L, the remocal rate of COD in two-stage effluent reached 35.0%~42.6%, meeting the emission standard for petroleum chemical industry(GB 31571-2015). Compared with the one stage aeration process production test device, ozone consumption for per unit COD of the selected optimized technology was 1.04 g/g and reduced by 21.2% comparing with the original process (single stage ozonation).
