摘要
依据水环境功能区划分原则及技术方法对山西桑干河干流地面水域的功能区进行了划分。根据桑干河干流实际的水文特点,建立了桑干河干流氨氮、COD及挥发酚环境容量的计算模型,最终对不同频率流量条件下的桑干河干流氨氮、COD及挥发酚环境容量进行了计算、分析。
The water environmental protection zones were partitioned according to the functions assigned to the sections of the main stream of Sanggan River in Shanxi Province. According to the practical hydrographic characteristics of the main stream of the Sanggan River, a model of the ammonia nitrogen, COD and volatile hydroxybenzene environmental capacity of the Sanggan River was established, and with which the different flow frequencies were calculated and analyzed.
