河流纳污能力计算方法比较

摘要

Based on the hydrological conditions, water quality targets, and one-dimensional water quality modeling theory, different water environment capacity calculation methods for a river system were examined by considering different sewage outlet positions, selections of control cross-sections, and allocations of dilution capacity. Through a case study of the Feiyunjiang River in Wenzhou City, the influences of the different calculation methods on the calculated results of water environment capacity were analyzed, and the advantages, disadvantages, and applicability of these methods were compared. This provides the technical basis for calculation of water environment capacity in river systems.%在一定水文设计条件和水质目标前提下,根据一维河流水质模型理论,探讨基于不同排污口位置、不同控制断面设定、不同稀释容量分配情景下的河流纳污能力计算方法,比较其结果的差异性.以温州市飞云江河段为例,分析不同计算方法对河流纳污能力计算结果的影响,提出各种方法的优缺点及适用性,为河流纳污能力研究提供技术依据.
