絮凝法处理油田高含盐含油废水的试验

Treatment of oilfield wastewater with high concentration of salt and oil by flocculating method

针对陕北油田高含盐、含油有机废水的特点 ,介绍了适用于处理该类废水的高效、廉价的复合型絮凝剂 XG2 1 3。试验表明 ,采用 XG2 1 3絮凝剂处理后的废水 ,其水质达到了油田回注水的标准。

According to the nature of organic wastewater with high concentration of oil and salt in Shaanxi Northern Oil Field,a composite coagulant XG213 with low cost but high efficiency was introduced to treat the wastewater.Laboratory test shows that after treatment the wastewater will completely come up to the standard of refilling water for oilfields.
