Abstract: Fiber filter was used to treat petrochemical wastewater in Huajin Group, which makes the effluent reach A grade discharge standard of “discharge standard of pollutants for municipal wastewater treatment plant” (GB 18918-2002). The principle, design parameters and treatment effects of fiber filter were discussed. The results indicate that the average water inflow is 2100 m3/h during the stable operation stage. The average concentrations of chemical oxygen demand (CODCr) , suspended solids (SS) and turbidity of water inflow are 50 mg/L, 15 mg/L and 15 mg/L, while those of effluent are less than 30 mg/L, 10 mg/L and 15 mg/L. The treatment effects of fiber filter are better, especially for SS and turbidity.
