| 摘 要： | 采用BOD5/CODCr法和瓦勃呼吸仪分别对炼油废水、聚合物驱采油废水和高含盐采油废水的可生化性进行了分析评价.结果表明:炼油废水和聚合物驱采油废水具有可生化性,而高含盐采油废水可生化性极差.在两种评价方法中,BOD5/CODCr法方法简单,易于操作,但可靠性差;瓦勃呼吸仪法通过测定微生物的呼吸曲线,能更加准确地反映废水的可生化性,为废水能否采用生物处理提供了一定的实验依据.

| Abstract: | The biodegradability of the refinery wastewater,the polymer displacement wastewater and the high-salinity wastewater from oilfield are analyzed and evaluated by BOD5/CODCr and Warburg respiration apparatus.The results indicate that the refinery wastewater and the polymer displacement wastewater are biodegradable,but the high-salinity wastewater from oilfield is not easy to be directly biodegraded.Compared with using Warburg respiration apparatus,BOD5/CODCr evaluation method is simpler and easier to operate,but its reliability is worse.The breath curve of microorganism determined by Warburg respiration apparatus can more accurately reflect the biodegradability of wastewater,and it can provide the experimental basis for the biological treatment of wastewater in the future. |
