An Overview on Oily Wastewater Treatment Technology for Ships

Since the 21st century, with the increasing growth of the global economy, the world's countries are becoming more and more closely linked, relying on the sea and the ship transport has become the main mode of transport of foreign trade, but the shipping industry is booming at the same time also caused a lot of irreversible damage to the marine ecological environment, the ship's oily wastewater from a wide range of sources, the production of huge, complex water quality and environment has always been the difficult problem of sewage treatment, the ship's oily wastewater treatment processes and theoretical methods. This paper summarises and analyses the process and theoretical methods of oily sewage treatment for ships by reviewing the relevant literature at home and abroad, and points out its future development trend. The results of the research can provide theoretical and technical support for the development and application of oily wastewater treatment process for ships.
