2015年胶州湾主要污染物入海量研究

A Study on Main Pollutants Flux of Jiaozhou Bay in 2015

根据2015年胶州湾水质监测结果和直排胶州湾污染源的统计数据资料,分析评价了胶州湾水质状况,并计算了入海河流、直排海企业和污水处理厂排放的废水总量及COD、氨氮等主要污染物的入海通量。结果显示,2015年胶州湾整体水质状况为一般,入海河流是陆源污染物进入胶州湾最主要的途径,主要原因是入海河流流量大,且污染负荷较重。建议制定并实施主要入海河流断面水质保护管理方案,落实各项海洋环境污染防治措施,改善海洋环境质量。

Based on the water quality monitoring results of the Jiaozhou Bay in 2015 and the statistical data of land-based pollution sources directly discharging into Jiaozhou Bay, the Jiaozhou Bay water quality was analyzed and the total pollutant amount from three kind of pollution sources(rivers, marine discharged enterprise and sewage treatment plant) and the main pollutants flux of COD and NH4-N were calculated. The results showed that the Jiaozhou Bay water quality in 2015 was general and the main pollution sources were rivers which directly discharged into Jiaozhou Bay. That is mainly because the rivers discharge was large and the pollution load was heavy. Therefore, it's recommended that the management system of the sea water quality protection should be formulated and implemented as soon as possible, also the various marine environment pollution prevention measures could be carried out in order to improve the quality of the marine environment.
