In the petrochemical industry, water is a necessity in the process of petroleum processing. The refining process of petroleum products is long, and the production equipment and process are complex, which will produce a lot of petrochemical wastewater. Generally, the water quality of petrochemical wastewater is complex, which not only contains residual oil but also contains a lot of dissolved toxic substances. The direct discharge of these wastewater without treatment will cause serious damage to air, water and organisms.
Petrochemical wastewater is very harmful, so people use specific indicators to demarcate the pollution components in petrochemical wastewater. In order to deal with harmful petrochemical wastewater, protect water resources and reduce the harm of petrochemical wastewater to biology, many effective technologies have been developed. But many traditional technologies have the problems of large area, high cost, and low treatment efficiency, and the simple use of a wastewater treatment technology will cause a lot of waste of resources. Therefore, it is an important research direction to study the wastewater treatment process combined with various technologies and improve the efficiency of traditional wastewater treatment methods.
This thesis work describes the characteristics of petrochemical wastewater, the source, harm and the importance of treatment. It introduces the Membrane bioreactor (MBR), and more efficient catalytic wet air oxidation (CWAO).
