Abstract

The device for washing SOx in engine exhaust is a major measure to reduce SOx emission from ship combustion machinery. This paper reports on the methods of reducing suspended solids and polycyclic aromatic hydrocarbons (PAHs) in bleed off wastewater. Through the detailed tests on wastewater and by comparing the effects of coagulation sedimentation on suspended solids in wastewater with that of coagulation air floatation treatment, the influences of different factors on suspended solids are discovered. Meanwhile, by testing on polycyclic aromatic hydrocarbons adsorption processes, the study on the method of polycyclic aromatic hydrocarbons treatment is carried out and the relationship between different factors and polycyclic aromatic hydrocarbons adsorption rate are drawn. As a result of the research, the optimized compositions of coagulation and the optimized operation conditions of coagulation sedimentation and coagulation air floatation treatment are obtained in this paper. The results of this research and of the final exhausted wastewater examinations show that, the combined method of coagulation, dissolved air floatation and active carbon adsorption is an effective measure to treat wastewater from SOx scrubber and can make the turbidity, polycyclic aromatic hydrocarbons concentration of exhausted wastewater meet International Maritime Organization requirements.
