摘要：This work studies the effects of "Catan" type heterogeneous metal complex catalysts on the treatment of oil-containing water with active sludge. Both studied catalysts, but primarily catalyst 525, were able to eliminate oil from standard and real wastewater even without active sludge. The catalyst 525 and catalyst 524 also reduced the chemical oxygen demand (COD) in the oil-containing wastewater. According to the COD indicator, catalyst 525 was also more effective than catalyst 524. However, the greatest decrease in COD was observed in systems where both active sludge and "Catan" type catalysts were used. Thus, the joint use of "Catan" type catalysts and activated sludge significantly increased the removal rate of petroleum products and improved the quality of oily wastewater.
