摘　　要：以芜湖市长江沿线澛港圩区内污水处理厂尾水排放为例,充分考虑圩区内水利工程的调度规则、受纳水体的环境保护目标、污水处理厂运行工况等因素制定预测方案,分别采用一维稳态数学模型和二维水量水质数学模型对内河和外河的影响进行预测,根据预测结果提出了对受纳水体影响最小的排放方案,为决策部门提供了科学依据。Taking the tailwater discharge of sewage treatment plant in Lugang polder area along the Yangtze River in Wuhu City as an example,the prediction scheme was formulated with full consideration of the dispatching rules of water conservancy projects in polder area,the environmental protection objectives of receiving water bodies and the operating conditions of sewage treatment plants.One-dimensional steady-state mathematical model and two-dimensional water quantity and quality mathematical model were used to predict the influence of inland and external rivers.According to the prediction results,the discharge scheme with the least influence on receiving water bodies was proposed,which could provide a scientific basis for decision-making departments.
