常温含油污水处理是不加热集油和脱水的配套技术.经过三年的试验研究已获得成功,并已通过大庆石油管理局的鉴定. 研究结果表明:含油污水原水在水温30～34℃,含油量≤5000mg/L的情况下,经处理后水质达到《大庆油田砂岩油藏注水水质标准》.试验采用的主要处理工艺是:原水经缓冲除油、粗粒化、沉降、过滤四级处理,反冲洗水需加热到55℃以上.该技术为新
Oily sewage treatment at room temperature is not heating oil and dehydration supporting technology .After three years of experimental research has been successful and has been identified by the Daqing Petroleum Administration.The results show that: oily wastewater raw water at the water temperature of 30 ~ 34 ℃, oil In the case of ≤5000mg / L, the water quality of the treated water reaches “Water Quality Standard of Sandstone Reservoir in Daqing Oilfield.” The main treatment processes used in the experiment are as follows: the raw water is treated by buffering, degreasing, coarse graining, sedimentation and filtration, Backwash water needs to be heated to above 55 ° C. This technology is new
