The content of oil, suspended solids, COD and other pollutants in emulsified waste water treated through the emulsified waste water treatment oil removing agent is greatly reduced, and when the emulsified waste water treatment oil removing agent is used, the feeding quantity is small, and treatment cost is low. Waste oil can be recycled after being treated, the waste water reaches the standard, and benefits can also be created. When the emulsified waste water treatment oil removing agent is applied, equipment modification is very small, investment is small, and the treatment effect is remarkable. The treatment operation is easy, high reliability is achieved, and management is facilitated. The emulsified waste water treatment oil removing agent is free of toxins, harm and secondary pollution, and up-to-standard emissions of the waste water can be ensured. The treatment effect is good in stability, and popularization is facilitated. The application range is wide, the recovery rate of oil products can be increased, the oil content in drained water can be reduced, and stable running of subsequent treatment units is promoted.

The invention relates to a preparation method of an electrostatic absorption heating slurry prepared from a graphene carbon nano tube. The electrostatic absorption heating slurry comprises 3-10 partsof graphene, 1-5 parts of carbon nano tube and 0.5-2 parts of carbon black according to mass percentage; and the resistance of a film surface is less than 107 Omega / sq. The preparation method of the electrostatic absorption heating slurry prepared from the graphene carbon nano tube, provided by the invention, has the advantages that the content of the graphene is reduced, and the production cost is reduced because the graphene, the carbon nano tube and the carbon black are used in a coordinated manner; moreover, by adjusting the mixing ratio of the graphene, the carbon nano tube and the carbonblack to an appropriate mixing ratio, the anti-static electricity performance of a heating film is enhanced, and the content of the graphene can also be reduced.
