聚合物驱采油废水的活性污泥处理研究

Study on activated sludge treatment of polyacrylamide wastewater from oilfield

聚合物驱采油废水为进水,采用逐渐加压法对好氧活性污泥进行驯化。结果表明,在进水中聚合物驱采油废水所占比例为15%～30%,曝气12 h的条件下,驯化污泥对进水CODCr的去除率可达70%左右,除油率高达76%,HPAM的降解率为40%左右。

The polymer flooding production wastewater as influent, gradual compression method was used to tame aerobic activated sludge. The results showed that when wastewater contained 15% - 30% polymer flooding produced wastewater,aerated for 12 h ,flooded CODCr removal rate was about 70% ,and oil content removal was higher than 76% ,and the degradation rate of HPAM of the activated sludge was 40%.
