摘要
某县域为离子型中重稀土发源地之一,原地浸矿稀土开采工艺造成一定程度的地表水体氨氮污染问题.概述了该区域地表水体氨氮污染状况,分别解析了水体氨氮污染对人体健康和生态环境的危害,提出了"控源—截污—清淤—修复"相结合的水体氨氮污染控制策略,提出了无氨浸矿、优化浸矿工艺等控源措施;通过超声波强化厌氧氨氧化工艺及太阳光强化氯氧化技术提高截污效果,大大提升截污效率,节省截污成本;列举了机械清淤、水力清淤、人工清淤以及生物疏浚等清淤措施;并采用原位与异位技术对水体进行修复.最后从组织管理、制度措施和经费保障3个角度阐述了水质达标保障措施,旨在为水体氨氮污染治理奠定基础.
Abstract
A county is one of the birthplaces of ionic medium and heavy rare earths,and the in-situ leaching rare earth mining process has caused a certain degree of ammonia nitrogen pollution in surface water.This paper summa-rized the status of ammonia nitrogen pollution in surface water in this region,analyzed the pollution hazards of am-monia nitrogen in water to human health and ecological environment,proposed a water ammonia nitrogen pollution control strategy combining"source control,sewage interception,dredging and restoration",and proposes source control measures such as ammonia-free leaching and optimization of leaching process,dredging measures such as manual dredging and biological dredging,and restoration of water bodies from in-situ and off-situ sources.Finally,the water quality safeguard measures are expounded from the perspectives of organization and management,institu-tional measures and financial guarantee,aiming to lay the foundation for the control of ammonia nitrogen pollution in water bodies.
