油田含聚污水聚结气浮处理工艺实验研究

Experimental study of oilfield polymer-bearing wastewater coalescence-flotation treatment process

设计了一套聚结技术与溶气气浮技术联用的油田采出水处理装置,在孤五联进行了现场试验,考察了聚结材料类型、结构形式、停留时间、溶气水回流比对聚结气浮装置除油效果的影响,试验装置在不加药情况下除油率最高可达87%,处理后污水含油量小于200 mg/L。

Design a coalescence associated with dissolved flotation device used for oil field produced water,Conducted a field test in Guwulian,Study coalescence type of material, structure,residence time,dissolved gas and water reflux ratio on the rate of oil removal devices, experimental device without the case of chemical agents up to 87%oil removal rate, the treated effluent oil content less than 200 mg/L.
