Description

Technical Field

[0001] The utility model relates to the technical field of oily wastewater treatment, and in particular to a graphene sponge ball filter skid and an oil-water separation system. Background Art

[0002] A large amount of oily wastewater is generated in the petrochemical industry. If it is directly discharged into the environment, it will cause serious pollution to the water body. Oil-water separation can effectively remove the oil in the wastewater and reduce the impact on the environment. Through oil-water separation, the oil in the wastewater can be extracted for reuse, reducing resource waste.

[0003] The commonly used oil-water separation technologies in the petrochemical industry are physical flotation and chemical demulsification technology. The physical flotation method forms tiny bubbles by introducing compressed air into the wastewater through a releaser, so that the oil droplets are attached to the bubbles and float to the water surface. It is suitable for the treatment of low oil content or emulsified oil, but the equipment of this method occupies a large area and the equipment investment cost is high. The chemical demulsification technology destroys the emulsified state of oil and water by using demulsifiers, promotes the aggregation of oil droplets, and improves the subsequent separation efficiency. It is particularly suitable for the treatment of emulsified oil wastewater, but this method requires the addition of chemical agents, the process is complicated, the cost of agents is high, the operating cost is high, and the added agents often become new pollutants.
