Abstract :
Because of poorly biodegradable in oily sewage, physicochemical methods are often used to treat the oily sewage. However, we have developed ways to break apart strains that can efficiently degrade COD and high polymer HPAM. In this paper, Flora biological strengthening technology and Hydrolysis-Acidizing-Bio-contact oxidizing treatment are used in oily sewage. As a result, oil removal is about 98% by biodegradation and strengthened. The removing rate of COD and HPAM is 48.4% and 48.5% respectively, that can reach the oilfield sewage discharge standard.
