针对辽河油区稠油污水粘度大、油水密度差小、乳化严重、水温高、水质水量变化大的特点 ,研制了高效净水药剂 ,并利用该药剂对欢四联、杜 84块稠油污水及兴一联稀油污水进行处理。结果表明 :当药剂TJ 1投加量为 75～ 10 0mg/L ,絮凝剂P 3投加量为 1～ 3mg/L ,GT值控制在 10 4～ 10 5范围内 ,处理后的水清亮透明。其含油量为 1mg/L左右 ,去除率可达99 9%以上 ;悬浮物为 4mg/L左右 ,去除率可达 98 5 % ;COD为 2 0 0mg/L左右 ,去除率可达96 9%。
Aiming at the characteristics of heavy oil wastewater in Liaohe oilfield such as high viscosity, small oil-water density difference, serious emulsification, high water temperature and great changes in water quality and water quantity, a high efficiency water purifying agent was developed. And Hing Fat dilute sewage treatment. The results showed that when the dosage of TJ 1 was 75 ~ 100 mg / L, the dosage of flocculant P 3 was 1 ~ 3 mg / L and the GT value was controlled in the range of 10 4 ~ 10 5, the treated water was clear and transparent . The oil content of about 1mg / L, the removal rate of 99 9% or more; suspended solids 4mg / L or so, the removal rate of 98 5%; COD of about 200mg / L, the removal rate of 96 9% .
