| 摘 要： | 稠油乳化段废水中的主要污染物为有机聚合物和石油类污染物，BOD5／COD值极低，可生化性差，通过厌氧处理可使污染物发生水解反应，BOD5／COD值由0．08升为0．15（288h)，与其它难降解有机废水的厌处理结果不同，在BOD5增加的同时，COD亦大幅度增加，而在全部厌氧反应过程中，TOC一直呈下降趋势，表明水样中的污染物在生物作用下不断得到消减；在COD达到最高时，石油类污染物中胶质的浓度大幅度降低，烷烃的浓度升高，说明以胶质为代表的大分子污染物因子解反应，由K2Cr2O7不能氧化状态变为可氧化状态，导致COD测量值显著升高。

| Abstract: | The main pollutants of viscous oil production wastewater in emulsification stage were organic polymer and petroleum. The COD was higher whereas BOD 5 lower. The value of BOD 5/COD was only 0 08. Through anaerobic pretreatment, the ratio of BOD 5 and COD increased to 0 15 (288h). The abnormal result was that with the increase of BOD 5, the concentration of COD (144h) reachedup to 534mg/L from 324mg/L. TOC decreased gradually in the whole process, with meamt that polymer and petroleum, especially resin, degraded to small molecule and could be oxidized by K 2Cr 2O 7 after anaerobic process. The results in this paper have been applied to the design of a produced water treatment plant. |
