【摘要】 可发性聚苯乙烯废水中含有大量表面活性剂（LAS）和其他一些难降解的苯环类物质,总磷高,可生化性差,较难处理,采用中和混凝沉淀-活性炭生物池工艺处理可发性聚苯乙烯（EPS）废水,当进水平均COD_Cr为1800mg/L时,出水在80mg/L左右,去除率达95.5%,出水水质稳定,各项水质指标均达到了国家一级排放标准。更多还原

【Abstract】 Expansible polystyrene（EPS） wastewater involves large quantities of organism containing benzene loop such as surfactant LAS and so on with high total P index and bad biodegradability.It is hard to treat it.The process of flocculative sedimentation-active carbon biological tank is adapted to treat EPS wastewater.When average COD_Cr of original wastewater is 1 800 mg/L,that of the effluent can reach about 80 mg/L with the removal rate of 95.5%.The effluent quality remains stable and several quality indexes of the effluent can meet the first class criteria specified in the national discharge standard.更多还原
