摘要:
通过分析海上油田生活污水的产排特点，针对性地开发了一种海上油田生活污水一体化处理装置，采用“接触氧化+MBR”工艺，将预处理、厌氧、好氧、MBR及杀菌消毒等工艺合为一体。经过现场调试及连续5 个月的运行跟踪，该一体化装置对COD及NH4+-N的平均去除率分别为91%和89%，出水水质可达到《城市污水再生利用 城市杂用水水质》（GB/T 18920—2002）的指标要求，并在海上平台实现冲厕回用。该装置具有防污堵、操作简便及自动化程度高等特点，出水水质可长周期稳定达标，适用于海上油田生活污水处理。
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.
