Abstract:

With the development of industrial technology, marine litter has become a noticeable issue in ocean governance.Huge amount of marine litter distributes widely all over the world. Marine litter includes plastics,wood products,paper products and metals,among which plastics are the main components.Marine debris not only causes visual pollution and vessel safety hazards,but also seriously threatens the marine biology and ecological balance.In the review on marine litter treatment technologies,the treatment procedure can be divided into three steps:locating and monitoring,collection and treatment.Deep learning has already been applied to the automatic detection on marine litter. In terms of collection,traditional devices,such as cleaning vessels,still play a dominate role,while new devices,such as automatic water surface cleaners,are in ongoing development and improvement.The treatment methods of marine debris mainly include landfill,incineration,pyrolysis and microbial technologies.Pyrolysis not only avoids the production of pollutants such as dioxins,but can also be used to produce additional products such as fuel oil with high calorific value,which facilitates the recycling of energy from marine litter.Next,it will become an inevitable trend to develop a collaborative system integrating pollutant positioning,collection and processing.

Key words: marine litter, locating and monitoring, treatment technology, deep learning, thermochemical treatment, pyrolysis, waste-to-energy
