摘要
根据甘肃玉门油田废水水质的实际情况,采用絮凝沉淀法对其进行处理,以期降低回注水中的总铁含量,满足其回注要求。通过实验室实验总结出了PAC处理该油田废水的最佳条件：PAC投加量5mg/L,pH值7.5,水温25℃,沉淀时间15min,在此条件下出水总铁可满足回注的要求。
According to the actual conditions of the wastewater in Yumen oil field of Gansu province, the method of floeculation and precipitation is chosen to reduce total iron content to meet its recycle demands. The optimun condition is concluded by experiment： PAC 5 mg/L, pH 7.5, water temperature 25℃, time of precipitation 15 min. The total iron in treated wastewater can meet the demand of recycle.
