Embodiment 1
[0028] Embodiment 1, foam conveys polystyrene nanoparticles
[0029] The suspension of polystyrene nanoparticles is added in the surfactant (sodium lauryl ether sulfate) solution, and the surfactant concentration is 1%, and the solution is injected into a plexiglass column (diameter 10mm, length 100mm) with a pump, At the same time, feed nitrogen into the column to generate foam, and control the dryness of the foam at about 95%. Inject the generated foam into a column (diameter 40mm, length 200mm) filled with quartz sand. The other end of the column is connected to a vacuum pump ( figure 1 It is a schematic diagram of the whole set of equipment), and the vacuum degree is controlled at 0.05-0.08MPa. Before the injection experiment, the quartz sand is pre-saturated with water, and before the foam containing nanoparticles is injected, the foam without nanoparticles is injected for pre-balancing. During the injection of the foam containing nanoparticles, samples of the outflow fo...
Embodiment 2
[0032] Embodiment 2, foam transporting nanometer zero-valent iron particles.
[0033] Using the same procedure as in Example 1, the nanometer zero-valent iron particles were transported into the quartz sand with foam. The concentration of nano-iron is greater than 5 g / L. The results show that the concentration of nano-iron particles in the outflow foam is more than 80% of the concentration in the injected foam, indicating that the foam can also significantly improve the migration of nano-iron particles in the quartz sand.
