某港口石油类环境容量研究

Study on the environmental capacity of petroleum in a port

青岛某港口承担重要的靠泊通航任务,是国家重点建设港口。港口东、南、西3个方向建有6段防波堤,水体交换能力不强。实地取样得到该港域海水样品并进行检测,用Arcgis制作污染分布图,利用Mike21软件中的水动力和对流扩散模块,考虑潮汐影响,模拟得到水体交换周期为9天。根据水体输运数据,计算水体交换周期和本底含油量,得出港区石油类环境容量,为港区环境管理提供科学依据。

A port in Qingdao undertakes the important task of berthing and navigation, and it is a important port of national construction. Six sections of breakwaters are built in the east, south and west directions of the port to encircle it,so the water exchange capacity is not strong. In this paper, the seawater samples in the harbor area were collected and detected, and the pollution distribution map was made by Arcgis. Using the hydrodynamic and advection dispersion module of Mike21, considering the influence of tide, the simulation results show that the water exchange period is 9 days.According to the water transport data, the water exchange period and background oil content are calculated, and the oil environmental capacity of the port area is obtained, which provides a scientific basis for the environmental management of the port area.
