Progress in Petrochemical Wastewater Treatment

Abstract

Untreated or poorly treated petrochemical effluent can damage plants and animals in natural water bodies. It is a major industrial contaminant that creates several harmful chemicals. As a result, creating a straightforward, effective wastewater treatment technique is crucial. At this stage, countries around the world attach great importance to environmental protection and constantly improve the requirements for wastewater treatment, especially petrochemical wastewater. To meet the water treatment standards, the relevant personnel have continuously strengthened the research of wastewater treatment technology, and have achieved good results. This paper introduces the types and discharge characteristics of pollutants in petrochemical wastewater and summarizes the research progress of petrochemical wastewater treatment technology. In this paper, three wastewater treatment technologies, namely electromagnetic method, BAF, and suspension packing bioreactor, are analyzed, and the problems and challenges of the current wastewater treatment technology are proposed.
