【Abstract】 The structure of the filter and the hydrophilic and oil repellent modified filter ball filter media were presented. Based on the water quality, the compacting fiber ball filters or non compacting fiber ball filters may be selected. The application test in Daqing Oil Field shows that the modified fiber ball filters were characteristic of high filtering speed, and large amount of treatment, and suitable for the depth treatment of oily sewage in the polymer drive oil fields. The quality standard of the water injected reached that of the water on the low permeable beds.更多还原
