The waste lubricating oil mainly comes from the oil replaced by various mechanical equipment. At present

the recycling technology of waste Lube oil in common use in China is acid process. In order to know the influence degree of this process on atmosphere environment

water environment and solid waste disposal about waste lubricating oil recycling technology. Distinguish pollution prevention control measures and effects systematically

it is found that the waste gas pollution includes vacuum tail gas

combustion flue gas and non-organized waste gas

and the water pollution is mainly oil-bearing waste water through the traceability analysis of pollutants. Under the measures of full combustion

oil separation and air floatation

reasonable disposal of waste clay

the concentration of SO2emission can be lower than 10 mg/m3

the concentration of NOxemission can be lower than 160 mg/m3

and the content of petroleum in waste water can be lower than10 mg/L

the waste white clay can be disposed of safely

it can meet the corresponding discharge requirements

and the impact is accepted by surrounding environment. On this basis

good application of regeneration technology can reduce the loss of base oil and improve the utilization rate of petroleum resources

which has certain economic and environmental benefits.
