Background
The thermal cracking process conforms to the recycling and harmless principle of waste treatment, and becomes an effective mode for treating waste tires at present. The thermal cracking treatment of waste tyre is carried out by heating tyre in oxygen-free or inert gas environment, decomposing at a certain temperature, and recovering pyrolysis oil, pyrolysis gas and carbon residue. Therefore, the industrial wastewater generated by the pyrolysis project contains pyrolysis oil and carbon slag, and if the industrial wastewater is discharged, water resources and land resources are polluted, the ecological environment is destroyed, and the industrial wastewater does not meet the national wastewater discharge standard.
The conventional wastewater treatment methods at present comprise the following steps:
1. the gravity suspension technology comprises the following steps: by utilizing the density difference between oil and water, the oil can float on the surface of the water, and the oil-water separation is realized. The technology has low oil removal efficiency and larger volume of the using device.
2. Chemical agent degreasing: the colloid particles are aggregated and settled by using chemical agents, thereby realizing the purpose of wastewater treatment. However, this method causes chemical contamination, increases the cost of chemicals, etc., or causes clogging of equipment, lowering the treatment efficiency.

However, if the inlet water concentration of the sewage is higher, the blockage can be caused, the filtering effect can not be achieved, and even a large amount of water is needed for cleaning, so that more waste water is treated.
4. The hydraulic cyclone technology comprises the following steps: under the action of centrifugal force, the oil migrates towards the centre of the fluid vortex, while the water moves towards the other end. This technique requires a large pressure differential within the hydrocyclone and a high density differential between the oil and water, otherwise separation is difficult. And the hydrocyclone technology cannot effectively remove solids entrapped by oil.
5. Air flotation technology: air is introduced into the wastewater, and the generated small bubbles can adhere to and wrap oil and suspended solids in the wastewater, so that the density difference between the small bubbles and water is increased, and the floating speed of the small bubbles to the water surface is increased.
