Abstract:  

Oil bearing sewage containing polymer in GD Oilfield has the properties of high viscosity, high oil content and more suspended particles, and the conventional single flocculating agent has the disadvantages of high dosage, loose coagulation and high cost. Oil removal rate and removal of turbidity were chosen as the evaluation values in this test, and flask experiment was used to evaluate the sewage processing effect of three inorganic flocculants and two organic polymer flocculants. Inorganic flocculant of poly (aluminium ferric chloride) with the concentration of 100 mg/L and organic polymer flocculant of PAM 4 with the concentration of 40 mg/L were respectively selected as the best flocculant. The oil removal rate and removal of turbidity of waste water were 92.3% and 90.7% respectively when poly (aluminium ferric chloride) and PAM 4 were used to dispose oilfield waste water. Some influencing factors such as temperature, pH value and settling time were investigated. The experimental results showed that the oil removal rate and removal of turbidity of oilfield waste water which was disposed by using compound flocculant system were the best when temperature of waste water was 40~60 , pH value of waste water was 6~9 and the settling time was longerThe compound flocculant system has strong prospect in the processing of oil bearing sewage containing polymer.

摘要: 针对GD油田含聚含油污水黏度高、 含油量高、 悬浮颗粒多的特点, 而常规单一絮凝剂用量高、 絮凝体
松散、 成本高的缺点, 以除油率和去浊率为评价指标, 采用烧瓶实验对3种无机絮凝剂和2种有机高分子絮凝剂进行
絮凝效果评价, 优选出了质量浓度为1 0 0m g / L的无机絮凝剂聚氯化铝铁和质量浓度为4 0m g / L的有机高分子絮凝
剂P AM - 4为单一絮凝剂的最佳试剂。将两者组成复配体系后, 优选出最佳的絮凝剂经过复配絮凝剂体系处理后的
污水除油率和去浊率分别为9 2. 3%和9 0. 7%, 并评价了絮凝温度、 污水p H 及沉降处理时间对复配絮凝剂体系絮凝
性能的影响。结果表明, 该絮凝剂体系在4 0~6 0℃, p H为6~9及较长的沉降时间下, 处理效果最好。该体系在同
类含聚含油污水处理中应用前景较好。
