摘要
针对稠油污水粘度大、油水密度差小、乳化严重、水温高、水质水量变化大的特点 ,认为高效净水药剂的研制和开发是稠油污水处理的基础和关键。实验结果表明 :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。油含量为 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%
R&D of high effective purifying chemicals is one of the bases and keys in treating effluent from in situ heavy oil recovery according to its characteristics such as high viscosity, low oil/water ratio, serious emulsification, high temperature and wide variation. Experimental results demonstrate that oil content, SS and COD in the treated water are about 1 mg/L , 4 mg/L and 200 mg/L respectively, and their removal efficiency can reach over 99.9%, 98.5% and 96.9% respectively when dosages of chemicals TJ-1 and flocculating agent P-3 are at the rang of 75~100 mg/L and 1~3 mg/L respectively, at the same time, GT values are controlled at the rang of 10 4~10 5 .
