Application And Research Of Oil Pollutant Treatment Technology

With the continuous development and progress of human industry,petroleum energy use will continue to increase and in the exploration,development,transmission,refining process,because the process of accident or improper technique,resulting in oil pollution leakage to the ground,wetlands,rivers and fishing grounds,the local ecological environment subject to different degrees of pollution directly endanger people in the surrounding normal living environment.This paper gives a brief introduction of Jidong Oilfield in the oil pollutant treatment process,of oily sludge,sewage and other pollutants separation,filtration,adsorption and bacterial biochemical decomposition of the process processing and optimization.Currently in Jidong Oilfield using biochemical sewage treatment technology are "suspended and attached anaerobic-aerobic oxidation sewage biochemical process",is the combination of activated sludge and biofilm,in aerobic and anaerobic stage are exist in suspended sludge and biofilm,while maintaining a than general contact oxidation method is much higher biomass in anaerobic and aerobic pool,and in pond and culture has very strong degradation ability of oily wastewater photosynthetic bacteria,strengthen the ability to deal with,improve the treatment effect and the ability of anti shock loading.Sludge treatment device adopts the solvent washing-Waste Treatment-oil refining process,the sludge after heating,mixing,refining,settling,dewatering,and finally through the except oil pumping to centrifuge to separate fine solids and waste residue send Jidong Oilfield solid waste landfill field harmless landfill.After the treatment of petroleum pollutants oil in the process of exploration and development can be in harmony with the local ecological environment,at the same time,pollutant treatment technology of successful application,also can be of various oil fields to build oil pollution treatment projects play a certain reference role.
