针对常规核桃壳、石英砂滤料处理含聚污水效果较差的问题，开展了陶瓷滤料处理试验。试验对陶瓷滤料运行参数与处理效果之间的关系进行了研究，其最佳工况为滤速13 m/h、反冲洗周期24 h、反冲洗强度10 L/(S·m2)。现场试验表明，陶瓷滤料对含聚浓度低于90 mg/L的污水处理效果较好，含油及悬浮物去除效率都较高。在进水含油浓度低于100 mg/L、悬浮物浓度低于50 mg/L的情况下，出水达到了“5.5.2”指标要求，比现有核桃壳、石英砂滤料处理含聚污水效果更好。%Filtration is the key link of sewage treatment. In view of the poor effect of the conventional walnut shell and quartz sand filter material to deal with the poly-containing wastewater, the processing experiment of ceramic filter material was carried out. The rela-tionship between operation parameters and the treatment effect was studied. The optimum condition is the filter speed of 13 m/h , backwash cycle of 24 h , backwash intensity of 10 L/(S·m2).Field test showed that ceramic filter material is good for the sewage treatment effect which containing polymer concentration below 90 mg/L, oil and suspended solids re-moval efficiency is high, too. In the condition that oil containing below 100 mg/L in input water ,suspended solids content below 50 mg/L,the effluent can meet the"5.5.2"index re-quirements,which better than walnut shell and the quartz sand filter material.
