“ECA”新规对船舶靠泊期间大气污染物排放影响研究

Research on the Influence of the “ECA” New Regulations on the Emission of Air Pollutants during Vessels Berthing

摘要: “ECA”新规颁布后，船舶大气污染物排放清单也将发生变化。本次研究以天津港区散杂货船、集装箱船和滚装船为研究对象，通过动力法模型测算出船舶靠泊期间大气污染物排放清单，并筛选出污染物分担率较高的集装箱船舶。通过污染源等效的观点，结合ALOHA模型进行污染物扩散模拟，得出敏感区域氮氧化物浓度存在超标情况，需进一步治理。本次研究成果不仅是天津港区大气现状的反映，也是促成港区大气减排的重要理论基础。

Abstract: After the “ECA” new regulations are promulgated, the list of air pollutant emissions made by vessels will also change. In this study, we selected bulk carriers, container ships and ro-ro ships as the research objects. The air pollution emission list of vessels during berthing was measured by the power model, and the container ships were selected due to high pollutant sharing rates. According to equivalent pollution source method, using ALOHA model to simulate the diffusion of pollutants, it was found that the concentration of nitrogen oxides in sensitive areas exceeded the standard, so it needed further governance. The result of this paper is not only the reflection of the present air situation, but also an important theoretical basis for the implementation of atmospheric emission reduction plan in Tianjin port.
