- Abstract:
- This paper analyzed the production and discharge characteristics of domestic sewage in offshore oilfields, and developed an integrated treatment device for domestic sewage in offshore oilfields. The process consisted of contact oxidation and MBR, which integrated pretreatment, anaerobic reaction, aerobic reaction, MBR, disinfection and other processes into a whole process. After on-site commissioning and 5-month operation tracking, the average removal rates of COD and ammonia nitrogen of the integrated device were 91% and 89%, respectively. The effluent quality met the limits specified in The Reuse of Urban Recycling Water—Water Quality Standard for Urban Miscellaneous Water Consumption (GB/T 18920-2002), which could be used for toilet flushing and recycling on offshore platforms. The device has the characteristics of anti clogging, simple operation and high degree of automation, and the effluent quality can reach the discharge standard stably for a long period, which is suitable for the treatment of domestic sewage in offshore oilfields.
