- Abstract:
- The coupling process of air floatation and flat ceramic membrane was used to treat the mixed wastewater from oily refinery, stormwater and domestic sewage. The operation results indicated that the effluent indicators such as SS, COD, BOD5, NH4+-N, sulfide, volatile phenol and petroleum pollutants were less than 3.0, 50, 20, 8.0, 1.0, 1.0 and 10 mg/L, respectively, which were superior to the discharge limits of Emission Standard of Pollutants for Petroleum Refining Industry (GB 31570-2015). The coupling process had the advantages of stable operation, low treatment cost and good effluent quality, which could provide reference for other oil refinery wastewater treatment.
