ABSTRACT
Application or research of biological treatment technology are applied in some oil field present,oil refineries and gas fields in our country on the production process cannot avoid will produce a lot of waste oil which due to the oil operations,oil refining,storage,transportation and equipment maintenance the waste oil dump landfill will produce the pollution of environmental soil and groundwater in addition waste of the resources,there is must be recycling these waste the oil field as an example,the main process mode of domestic oil fields was transportation tank car cleaning sludge,in addition to the tank and flotation tank sludge oil,wash wells, collect sewage recovery of oil pool with heating settling method,partial separation of anic impurities and then transported to the joint station,mixing to fresh recovery liquid for to the high content of anic impurities in the waste oil, position,gravity settling performance is not good,cause heat deposition impurity content(especially the sulfide particles)is still high,oil recovery often influence the joint station produced liquid handling system for the smooth operation of the,such as plex matter deposition processing equipment,electric dehydrator of the collapse of the electric field,even breakdown electrode plate,and produced an increase in suspended solids in the water of low cost, convenient operation and management of sewage treatment technology has e a bottleneck problem to be solved.
In this study,select the field of flotation machine oil as the starting material, isolated and purified anic impurity removal ability of obacter johnsonii P2008,the bacteria can use the oil as the sole carbon source for growth and metabolism, the metabolism of the active substance and reversal of anic impurities in
