Research Summary on Water Pollution in China Port Area for Green Port Construction

Water transport has become one of the most important transport modes in many countries in the world due to its large carrying capacity, low transport cost and low energy consumption. As a hub for land-water transfer, due to frequent trade between ships and land, a large number of domestic sewage and oily sewage are discharged, as well as suspended pollutants generated during construction, etc., as a result, the problem of water pollution in port area becomes more and more serious. In order to carry out the strategy of sustainable development and the concept of green port development, it is imperative to carry out the research and prevention of water pollution in port area. Firstly, the sources and harms of the main water pollutants during the construction and operation of the port are summarized, then the spatial and temporal distribution characteristics of these water pollutants are expounded, finally, the water pollution in the port area is summarized on the basis of the literature analysis, in this paper, the author suggests to introduce ecological engineering to treat the sewage in port area, compares the gap between domestic and foreign ports in drawing up water pollution prevention plan, and points out the defects and deficiencies of the existing water pollution research and prevention in port area
