摘　　要：采用Fenton试剂-混凝沉降法,对某石化公司的丁苯橡胶废水进行了为期3个月的中试处理研究.结果表明,在进水的化学需氧量（COD）为600～1 100 mg/L、生化需氧量（BOD5）为140～250 mg/L、悬浮物（SS）为0～400 mg/L、pH值为4～11的情况下,经过Fenton试剂-混凝沉降法处理,系统出水COD小于350 mg/L,BOD5小于150 mg/L,SS小于50 mg/L、pH值为6～9,出水水质满足GB 8978-1996三级标准的排放要求,出水的BOD5/COD值由0.15 ～0.28提高至0.33 ～0.45,可生化性大幅提高.Styrene-butadiene rubber （SBR）wastewater from a petrochemical company was treated by Fenton＇ s reagent-coagulation sedimentation process in a pilot unit for three months.The results showed that the chemical oxygen demand （COD）,biochemical oxygen demand （BOD5）,suspended substance（SS） were less than 350,150,50 mg/L respectively,and pH value was 6-9 of effluent of SBR wastewater after treated by Fenton＇ s reagentcoagulation sedimentation process,under the COD,BOD5,SS of the influent of SBR wastewater were 600-1 100,140-250,0-400 mg/L respectively,and pH value was 4-11.The quality of effluent met the discharge requirements of the third standard of GB 8978-1996,and BOD5/COD value range from 0.15-0.28 to 0.33-0.45,the biodegradability of the effluent was improved significantly.
