【摘要】：某油田联合站污水处理系统采用"大罐沉降+悬浮污泥过滤"工艺,过滤后污水悬浮物指标基本达到了该注水区块要求,但是滤后合格的污水在出站前悬浮物含量却增加到10 mg/L,远超出注水水质要求。通过现场取样分析,判断污水处理系统暴氧是导致水质超标的主要原因。经过对污水处理系统进行氮气密闭改造,避免了污水暴氧,下半年悬浮物指标基本达标,合格率达到95.62%,最终使得出站水质悬浮物含量小于5 m g/L。介绍了联合站污水处理存在的问题、污水处理问题产生的原因、工艺流程的密闭改造、密闭改造的效果等内容。
[Abstract]:The sewage treatment system of an oil field combined station adopts the technology of "large tank sedimentation suspended sludge filtration", and the index of suspended sludge after filtration basically meets the requirements of the water injection block. But the amount of suspended matter at the exit station increased to 10 mg / L, well above the water quality requirement. Through field sampling and analysis, it is determined that the main cause of water quality exceeding the standard is the oxygen burst in the sewage treatment system. After the nitrogen airtight modification of the sewage treatment system, the effluent oxygen explosion was avoided, the suspended matter index basically reached the standard in the second half of the year, the qualified rate reached 95.62, and finally the suspended matter content of the water quality was less than 5 mg / L. The problems existing in sewage treatment of combined station, the causes of sewage treatment problems, the airtight transformation of technological process and the effect of sealing transformation are introduced.
