摘要
针对陕北某油田处理采油污水絮凝剂投加量和污泥产生量大的特点,采用"先回流污泥后絮凝"的方法进行降低污泥产生量研究,探讨了常规简单絮凝和"先回流污泥后絮凝"处理中污水pH、絮凝剂投加量、回流污泥量等因素对污泥产生量的影响。结果表明,"先回流污泥后絮凝"处理工艺能显著降低絮凝剂用量和污泥产生量,其中PAC和PAM投加量分别降低81.25%和50%,污泥产生量降低48.40%。处理后污水可达到SY/T 5329-1994回注水要求。
Produced water treated in a ShanBei oilfield resulted in a great amount of coagulant dosage and sludge yield.This paper provided the way ＂reflux sludge and then flocculate＂ to reduce the amount of sludge yield.It was discussed that the difference between traditional flocculation and the new method ＂reflux sludge and then flocculate＂in respect of pH,coagulant dosage,refluxing sludge yield.The result showed that the new metho＂reflux sludge and then flocculate＂can reduce the amount of coagulant dosage and sludge yield observably PAC was reduced by 81.25%,PAM was reduced by 50%,sludge yield was reduced by 48.40%.Treated effluent can achieve injection water requirements SY/T 5329-1994.
