摘要：Electric desalting wastewater(EDW)is one of the petrochemical wastewater generated in the production process of petrochemical industry,due to the instability of its water quality,the traditional wastewater treatment technology is complex,high energy consumption,and will produce waste causing secondary pollution,posing challenges in terms of environmental protection,technology,and economy.This study utilized an on-site test to investigate the possibility of a new short-process physical method to replace traditional electro-chemical,oil-separation,and two-stage air floating physical chemistry processes,in response to optimizing the treatment effect,thus reducing the cost of treatment and carbon emissions.Following this test,this new short-flow physical method process could improve the efficiency of oil and suspend solid(SS)removal by 15.48%and 58.72%,and providing 78.37%and 75.55%the operating costs and carbon emissions savings,respectively.This system also reduced the production of waste solids,volatile organic compounds,and other three-waste compared with the traditional process.These benefits offer environmental and economic advantages,and this process serves as an efficient strategy to treat wastewater for electric desalination,and can be served as a completely new technological and process option for the treatment of EDW.
