s are different from modified fiber balls. First, the fiber ball filter material has a white spherical appearance, and the modified fiber ball filter material is golden yellow. Modified fiber ball filter material has better adsorption effect than ordinary fiber ball filter material. Secondly, modified fiber ball filter material is treated with ordinary fiber ball filter material. The effect is both in adsorption and filtration. It is better than ordinary fiber ball filter material. The mechanism of fiber ball filter material to remove oil and organic matter is: direct blocking, inertial blocking and electrochemical adsorption. The oil content of the water before filtration is ≤15mg/L, and the filter material of the suspended fiber ball is ≤10mg/L; the oil content of the water after filtration is ≤5mg/L, and the suspended matter is ≤2mg/L.
The surface of the Fiber ball
is modified and treated to strengthen the adsorption of oil and organic matter; the new ligation method of the modified fiber ball, the porosity of the filter layer is gradually reduced along the direction of water flow during operation, forming a filter material that is larger and smaller than the fantasy Pore dispersal form, better filtering result; high filtering speed, up to 25-30m/h. The filter material only needs to be supplemented by about 10% per year, and there is no need to change it. It is understood that the fiber bundle modified fiber ball filtration technology has a common fiber fan layout, hydrophilic and oil-proof, backwashing regeneration is simple, easy, and more complete. According to water quality requirements, the filter layer can be adjusted to shrink the scale and meet the requirements of different filtration accuracy. Wait. It is suitable for the filtration treatment of oil field produced water (especially low-permeability oil field reinjection water treatment), heavy oil oil field boiler reuse water deep treatment, and oil refinery oily wastewater degreasing treatment.
The filtering technology of the modified fiber ball filter material is applied to the oilfield sewage disposal project, and the disposal effect is excellent, and the quality of the effluent water meets the requirements of the oilfield reinjection water quality.
