含油污水高效处理系统试验研究

介绍了油田含油污水处理现状、现有处理技术及其发展情况。描述了污水处理及采出液处理现场实验工艺流程及主要试验内容。试验发现 ,当入口含油浓度在 6 0 0mg/L左右时 ,旋流处理后可降到 6 0mg/L ,再经气浮处理可降到 2 0mg/L左右 ;当入口含油在 2 5 0 0mg/L左右时 ,旋流处理后可降到 6 0 0mg/L ;若经气浮处理可降到 2 5 0mg/L左右。实际应用中应根据客观条件合理选择分离设备及其配套设备 ,形成一套高效的处理系统

Experimental Study on Oily-Sewage Disposal System

Sewage disposal technologies and the development in oilfields are introduced.The test technical programs and the main test contents of sewage disposal and produced fluid disposal are described.It is shown that when inlet oil cut is about 600mg/L,it can be reduced to 60 mg/L after hydrocyclonic separation,and then to around 20 mg/L after air floated;when inlet oil cut is about 2500 mg/L,it can be reduced to 600 mg/L after hydrocyclonic separation,and to around 250 mg/L if disposed by air floatation.In actual applications,we should reasonably select separation device and its equipped facilities according to objective condition so as to form a high efficient sewage disposal system.
