摘　　要：海上石油平台的生活污水,是造成海洋污染的重要因素,目前对其开展的在线监测尚处于起步阶段。本文依托实际项目,对基于紫外吸收法的生活污水化学需氧量(COD)在线监测数据进行质量控制,从实验室分析、平台现场比测和系统实际运行中获取的数据出发,展开质量评价,分析了数据差异的原因,并提出了下一步质量控制拟采取的方式方法,对在线监测技术在海洋石油勘探开发领域的应用推广具有参考意义。Domestic sewage from offshore oil platforms is an important factor causing marine pollution,and at present,online monitoring of the sewage is still in its infancy.Based on the actual project,the quality control of on-line monitoring data of chemical oxygen demand(COD)of domestic sewage based on ultraviolet absorption method is carried out from the data obtained from laboratory analysis,platform field comparison and actual operation of the system.The causes of data deviation are analyzed and the methods to be adopted for quality control in the next step are proposed.The results obtained in this paper have reference significance for the application and popularization of on-line monitoring technology in the field of offshore oil exploration and development.
