为解决稠油污水与含聚污水处理工艺中过滤器堵塞的问题，尝试利用可调制特性的环保陶球作为过滤介质代替传统滤料进行过滤研究。结果表明，环保陶球用于含油和含聚污水处理时过滤阻力小、节能、滤料不易板结。代替双层滤料进行稠油污水过滤，出水悬浮物含量平均为2.51 mg/L、含油量平均为0.18 mg/L；用连续砂过滤器和陶球滤料处理含聚污水，当不投加化学药剂时，出水悬浮物含量平均为24.5 mg/L、含油量平均为23.01 mg/L，再经过混凝、沉淀和压力过滤后，悬浮物含量低至2.69 mg/L、含油量低至0.95 mg/L。

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.
