Organic Pollutants Of Oil Fields In The Groundwater Analysis Determination And Remove Research Method

With the rapid development of economic, the production and use of oil becomemore and more important for the development of a national overall strengthmainstay .In the process of the production and utilization of the oil, it will produce theair pollution, water pollution , noise pollution and so on, especially, because of theterrain, human and other reasons, the underground water is polluted, it impacts thelocal residents daily water quality seriously, the people’s health can’t be guaranteed. Inthis paper, according to the analysis results of several water source wells in Jilin oilfield, we chose two of the pollutants DMP and long alkane hexadecane, studied theanalytical methods and the removing methods of the pollution.By using the high performance liquid chromatographic,we studied the method ofdetection the DMP. Get standard linear regression equation is Y = 110.33 + 198.07X,correlation coefficient R = 0.9997, DMP of dimethyl detection limit for 0.0090μg/mL,and the average recovery was 99.8%.By using the gas chromatograph,we studied the method of detection thehexadecane, the standard curve regression equation is Y = 388.36+ 180.90 X,correlation coefficient R = 0.9995, detection limit of 0.0250μg/mL , the averagerecovery was 99.4%.In order to remove the DMP in oil field groundwater , we studied the ozonemethod, active carbon absorption method, zeolite adsorption method, ozone-hydrogenperoxide oxidation method and activated carbon-zeolite adsorption method,ozone-activated carbon method. From the results, active carbon absorption method,active carbon-zeolite adsorption and ozone-carbon method shows the same result, themaximum value can all reach 99%. Considering the more simple operation, lower cost,less energy consumption conditions, we use the active carbon-zeolite absorptionmethod to remove the DMP in the oilfield groundwater .The ozone adsorption method, active carbon absorption and zeolite adsorptionmethods were used to remove the hexadecane. From the experimental results, we cansee that, active carbon absorption method can be remove the water trace hexadecanepollutants completely, the removal rate up to 100% which meet the standard of"zero" pollution. Above all, the two methods will not cause a secondary pollution to ourenvironment, and the methods which have high removal efficiency may play animportant role to solve the problem of oil field groundwater .
