三亚饮用水源地水库库区面源污染现状防治对策研究

Study on Prevention and Control of Non-point Source Pollution in Reservoir Area of Sanya Drinking Water Source Area

指出了农村面源污染是造成水源地水库污染的主要原因。分析和调查了三亚主要的饮用水源地水库库区面源污染现状。结果发现:农业生产活动和禽畜养殖是三亚水源地水库库区主要的面源污染类型,其中,农业生产活动对库区TN和COD污染负荷贡献达到70%以上,农业生产活动和禽畜养殖对库区TP污染负荷贡献达到了87%以上,在此基础上针对性地提出了三亚水源地水库面源污染的防治措施:三亚水源地水库库区面源污染防治应以农业生产活动和禽畜养殖的污染控制为主,辅以农业生活活动、库区管理和宣传教育等方面制定相应的污染物控制和管理措施。

Rural non-point source pollution is the main cause of water source reservoir pollution.Based on the analysis and investigation of the current situation of non-point source pollution in the reservoir area of Sanya’s main drinking water source area,this paper puts forward the prevention and control measures of non-point source pollution in the reservoir area of Sanya’s water source area.It was found that agricultural production activities and livestock breeding were the main non-point source pollution types in the reservoir area of Sanya water source area.Among them,agricultural production activities contributed more than 70%to TN and COD pollution load of the reservoir area,and agricultural production activities and livestock breeding contributed more than 87%to TP pollution load of the reservoir area.Therefore,the policy and measurement of Rural non-point source pollution control should focus on industrial production activities and livestock breeding,supplemented by agricultural life activities,reservoir management,publicity and education.
