试验证明,根据大庆油田的含油污水情况,采用粗粒化—斜板除油装置的除油效果是较好的。只要合理选择设计参数和工艺流程,在污水停留一小时的条件下,不投加混凝剂就可以把含油污水的含油量降低到注水标准以下。
Tests show that, according to Daqing oil field sewage situation, the use of coarse-grained - inclined plate degreasing device degreasing effect is better. As long as the reasonable choice of design parameters and process, the sewage stay for an hour under the conditions, without adding coagulant oil content of oil can be reduced to below the water injection standards.
