Petrochemical industry is also commonly referred to as petrochemical wastewater. For petrochemical wastewater, it contains many heavy metal substances. Therefore, the water treatment process of evaporative crystallization treatment can be preferably selected for industrial wastewater treatment, that is, part of the available resources can be recovered to reduce the operating cost after sewage treatment meets the discharge standard.

Petrochemical industrial wastewater, petroleum wastewater treatment equipment, how to deal with industrial wastewater
Petrochemical industry in the whole process of product processing unit operation complex and diverse products, the use of different raw materials produced by industrial sewage pollutants are different, so the nature of its water quality is complex and changeable, and the organic matter in wastewater such as its derivatives, hydrocarbons this kind of material content is high, the source of water is more complex, the water quality is unstable and other factors.
For the wastewater produced by petrochemical industry, Hongsen environmental protection petroleum wastewater treatment equipment mainly adopts biochemical method (anaerobic treatment, aerobic treatment, biological contact oxidation, membrane bioreactor, suspended filler bioreactor), physical and chemical method (oil separation, air flotation, adsorption, membrane separation), chemical method (flocculation, ozone oxidation, light oxidation, wet oxidation).
Biochemical method is also a biological method, as long as the principle is used by microbial metabolism of the water containing colloids, fine suspended state of organic pollutants into stable, harmless substances.
The physicochemical method is to recover the insoluble suspended pollutants in the wastewater, which uses the separation principle to make the sewage and other substances in a solid-liquid separation state.
Chemical method is a process in which the chemical properties of pollutants in this paper react with the added chemical agents, so that the industrial wastewater after the reaction can reach a discharge standard.
