【摘要】 城市排水管网与污水处理厂的运行状态直接影响受纳河流的水质。以河流水质为最终目标,根据河流纳污能力控制废水排放量,可有效保护河流生态质量。本文根据国际水协会发布的 1 号河流水质模型,构造了能模拟河流水质动力学和生化特征的仿真平台。进一步以河流断面氨浓度为控制指标,研究了基于河流水质的排水系统的排污流量控制问题。仿真结果验证了基于河流水质控制污水排放量策略的有效性。更多还原

【Abstract】 The urban sewer systems and the wastewater treatment plants have detrimental impacts on the receiving river water quality. Focusing on the river water quality, to control wastewater outflow discharge based on the receiving capacity of the river can preserve the river ecological quality effectively. Based on the River Water Quality Model no.1 (RWQM1) issued by the International Water Association (IWA), the simulation software for river systems is developed with MATLAB programming language, and the problem of wastewater discharge control focused on river water quality is studied by using the ammonia concentration at the river section as an index. Simulations verify the effectiveness of wastewater discharge control based on river water quality.更多还原
