摘要
东北地区某油田采油污水经处理后水质达标率低,为了提高水质达标率,污水处理采用斜板溶气气浮技术,研究斜板间距、回流比、表面负荷、絮凝剂投加量、气泡层厚度等对污水处理效果的影响,确定最优的参数值。在连续45天的现场试验中,该装置运行稳定。实验表明,与传统的溶气气浮法相比,斜板溶气气浮法处理含油污水的效果持续、稳定,处理后水体含油量可控制在10 mg/L以下。
Wastewater quality compliance rate is low after treatment in an oilfield in Northeast China, in order to improve the water quality compliance rate, inclined plate dissolved air flotation technology is used in sewage water treatment.Research on the wastewater treatment effect after using inclined plate spacing, reflux ratio, surface loading, flocculant dosage,gas bubble layer thickness etc.,to determine the optimal parameter values.In 45 consecutive days＇ experiments,the operation of the device is stable,the result is superior.Experiments show that compared to the traditional gas dissolved air floatation,inclined plate dissolved air floatation processing oily wastewater effect that can be sustained and stable, after processing the oil content in water control below 10 mg/L.
