摘　　要：以珠三角感潮河网区为典型研究区,借鉴美国最大日负荷总量(TMDL)水质管理理念,提出了面向水质目标达标的南顺联安围水环境治理思路。以黑臭水体代表性指标NH_(3)-N为例,基于陆域污染负荷和水体水质关联模型模拟手段,遵循“入河污染负荷计算-环境容量核算-污染负荷分配-工程措施预测”的思路,科学制定了NH_(3)-N排放总量控制精细化方案。经模拟计算,控源截污工程能削减NH_(3)-N入河污染负荷41.61 t/a,河涌水质达标率为92.66%,较工程实施前提升35.92%。河涌水质得到有效改善,基本实现区域考核目标。In the context of the tidal river network area of the Pearl River Delta,drawing inspiration from the water quality management concept of total maximum daily load(TMDL)in the United States,a strategy for the environmental governance of the Nanshunliananwei Water System was proposed,with the primary objective of achieving water quality target.Taking ammonia nitrogen(NH_(3)-N)as a representative indicator for the characterization of black and odorous water bodies,a simulation approach based on terrestrial pollution loads and water quality correlation models was employed.Following the conceptual framework of"pollutant loads calculation-environmental capacity assessment-pollutant loads allocation-engineering measures prediction",a refined NH_(3)-N emission control scheme was developed scientifically.Through simulation calculation,the pollution load of NH_(3)-N into the river can be reduced by 41.61 t/a through the source control and pollution interception projects.The water quality compliance rate in the river channels stands at 92.66%,marking a substantial increase of 35.92%compared to the conditions before the implementation of the engineering project.
