In order to solve the problem of filter clogging in the treatment of heavy oil sewage and polymeric sewage, environment- friendly ceramic balls with adjustable characteristics were used as filter material instead of the traditional filter material for filtration. The environment-friendly ceramic ball had the advantages of low filter resistance, energy saving and not easy to be hardened when it was used in the treatment of heavy oil and polymeric sewage. After the heavy oil sewage was filtered through the environment-friendly ceramic balls, the effluent suspended solids and oil content were 2.51 mg/L and 0.18 mg/L, respectively. When the polymeric sewage was treated by the continuous sand filter and ceramic ball filters without adding chemical agents, the average suspended solids content of the effluent was 24.5 mg/L, and the average oil content was 23.01 mg/L. After coagulation, precipitation and pressure filtration, the effluent suspended solids and oil content were 2.69 mg/L and 0.95 mg/L, respectively.
