Recently, oily wastewater treatment has become a hot research topic across the world. Among the common methods for oily wastewater treatment, coalescence is one of the most promising technologies because of its high efficiency, easy operation, smaller land coverage, and lower investment and operational costs. In this research, a new type of ceramic filter material was chosen to investigate the effects of some key factors including particle size of coarse-grained materials, temperature, inflow direction and inflow velocity of the reactor. The aim was to explore the optimum operating conditions for coarse-graining. Results of a series of tests showed that the optimum operating conditions were a combination of grain size 1–3 mm, water temperature 35 °C and up-flow velocity 8 m/h, which promised a maximum oil removal efficiency of 93%.

Oily Wastewater Treatment

Oily wastewater from shipping waste and marine accidents have seriously polluted the marine environment and brought great harm to human production and health. With the increasing awareness of environmental protection, the treatment of marine oily wastewater has attracted extensive attention from the international community. Marine oily wastewater has various forms and complex components, so its treatment technology faces great challenges. Sources, types, supervision, and treatment of marine oily wastewater are introduced in this paper. The research progress of marine and ship’s oily wastewater treatment technologies in recent years are reviewed from the perspectives of physical treatment, chemical treatment, biological treatment, and combined treatment, respectively. Principles and characteristics of all kinds of technologies were analyzed. In addition, this paper shows that multiple processing technologies used in combination for the purpose of high efficiency, environmental protection, economy, and energy conservation are the future development trend.

Oily Wastewater Treatment

Oily sewage is one of the wastes produced in the oil industry production process and its quantity has been increasing year by year, which influences the environment and human health severely. Electric flocculation method is one of the wide application electrochemical treatment technologies for the oily wastewater treatment at home and abroad, which has higher efficiency than other technologies at the aspect of the organic pollutants degradation. A simulative experiment device dealing with heavy oil sewage by the electric flocculation method has been designed in this paper. The mechanism of the electric flocculation method in removing organic matter of the heavy oil sewage by analyzing the change of the composition and content of the organic matter in water samples before and after the process of the electric flocculation has been studied. Research results show: the carbon/tin dioxide electrode is better than the carbon/ ruthenium dioxide electrode in removing organic matter; most alkanes matters in the oily wastewater have been removed in the dispersing oil form by the electric flocculation; as the current density increases, the types and quantity of the response organic matter can be improved while types of the new synthetic organics increase. At the same time, this paper provides a theory support in specific optimization of the electricity flocculation flotation in oily wastewater treatment technology and process.
