Pollutant Transfer and Transformation in Marine Environment and Application in the Study of Marine Environmental Capacity

海洋是地球表面最大的水体，通过水的自然循环，其他各类水体中含有的污染物都可能汇集到海洋中去，致使海洋污染日趋严重。因此研究污染物在海洋中的迁移转化机理，治理污染保护海洋环境已经迫在眉睫。目前国内外对污染物在海洋中迁移转化的研究，只限于对某一种污染物的单独研究，没有系统的总结，并且大部分都是定性的描述，缺乏定量计算。现有的关于污染物迁移转化研究的模型大多比较复杂、计算量较大、考虑的环境因子多，无法将其应用于海湾环境容量研究的数值模型计算中。本文针对这一问题，提供了一套能满足海湾环境容量数值模型计算的切实可行的污染物降解模式，并应用于实际案例中。 厦门湾的主要污染物是营养盐（氮、磷）、COD和石...Ocean is the largest water body on earth, and through the natural water cycle, pollutants contained in other types of water may all flow into the ocean in the end, so this poses a sever threat to marine pollution.

Determination and Application of Pollutant Transfer and Transformation Model in the Study of Xiamen Bay Environmental Capacity

海洋污染日趋严重,研究污染物在海洋中的迁移转化机理,治理污染保护海洋环境已经迫在眉睫。目前国内外对污染物在海洋中迁移转化的研究,没有系统的总结,大部分都是定性的描述,缺乏定量计算;相关模型大多比较复杂、计算量较大,无法将其应用于海湾环境容量研究的数值模型计算中。本文针对这一问题,提供了一套能满足海湾环境容量数值模型计算的切实可行的污染物降解模式,并且提出要控制总氮、总磷的理论,应用于厦门湾海洋环境容量研究中。Marine pollution problem become more and more serious,so the study of pollutant transfer and transformation mechanism in the ocean as well as pollution control and protection of marine environment becomes a critical issue.Currently,researches at home and abroad mainly focused on separate studies of the transfer and transformation process of certain pollutant in the ocean,whereas there is no systematic summary and most of them are qualitative description without quantitative calculation.Besides,models used by existing researches on pollutant transfer and transformation are mainly complicated,hard to calculate and involves a larger number of environmental factors,and thus not applicable to the numerical model calculation of the environmental capacity of bay areas.This thesis aims to solve this problem by providing a set of pollutant degradation model which meets the numerical model calculation of environmental capacity of bay areas,and applied the model to actual cases.我国近岸典型海域环境质量评价和环境容量研究(908-02-02-03)中的子项目——厦门湾海域环境质量评价和环境容量研究;项目代码:908-02-02-0

海湾中营养盐、COD和石油烃的迁移转化模式

污染物在海洋中的迁移转化,体现了海洋的净化能力。研究污染物在海洋中的迁移转化机理是海洋环境管理极为重要的内容。目前国内外对污染物在海洋中迁移转化的研究,只限于对某一种污染物的单独研究,没有系统的总结,并且大部分都是定性的描述,缺乏定量计算。现有模型大多比较复杂、计算量较大、无法将其应用于海湾环境容量研究的数值模型计算中。本文针对这一问题,提供了一套能满足海湾环境容量数值模型计算的切实可行的污染物降解模式,并且提出要控制总氮、总磷的理论,应用于厦门湾海洋环境容量研究中。我国近海海洋综合调查与评价(908专项

Estimation of marine pollution load in West Sea and Tong'an Bay in Xiamen

主要利用采用gIS、经验排污系数法和经验模型法,对厦门湾的西海域和同安湾两个海域的陆源、海上水产养殖和大气输入源的入海污染负荷进行估算,得出这两个海域的COdMn、总氮(Tn)和总磷(TP)年入海污染通量和入海污染负荷。估算结果显示,厦门湾的入海污染负荷主要来自于陆源污染源,所占比例在75.2%以上,大气沉降污染源次之,所占的比例平均为1.2%~18.4%,而海上水产养殖带来的污染负荷所占的比例最小,平均不超过1%。In this paper,the estimation methods of GIS,the experimental coefficient of sewage disposal and estimation model were mainly used to estimate the marine pollutants loads in West Sea and Tong'an Bay in Xiamen,including the pollution sources from the land-base,atmospheric deposition and aquaculture,and the annual pollutant fluxes of CODMn,TN,TP in every sea area.The estimation results of pollution fluxes and marine pollution loads of main pollutants(CODMn,TN,TP) in every sea areas were given.The result showed that the land-based pollution holds were the largest percentage of marine loads in every sea area,over 75.2%.The pollution source from the atmospheric deposition was the second proportion of 1.2%～18.4%.The pollutant from the aquaculture was the smallest proportion,less than 1%.我国近岸典型海域环境质量评价和环境容量研究(908-02-02-03
