【摘要】 水域纳污能力是指在满足水功能区水环境质量达标的基础上,水体中最大的允许纳污量。水域纳污能力的核算对水资源合理开发利用及有效保护具有十分重要的现实意义。河湖中的闸坝等水利工程会改变河湖的水文过程,从而对河湖水体纳污能力产生影响。以受人类干扰较为严重的典型闸控河道——通顺河为研究对象,采用模型法和污染负荷法,分析泽口闸取水流量10、13、15 m~3/s 3种情境下通顺河干流的水域纳污能力。结果表明不同引水规模对闸控河道的纳污能力影响不同,受多参数制约并不呈现出完全正相关关系。随着流域水污染治理工程的不断推进,河道引水规模越大,需要削减的污染物量越小。所提出的计算方案可为通顺河制定科学可行的闸坝调度规程提供依据,也可为河道治理提供对策和措施。更多还原

【Abstract】 Water pollutant carrying capacity refers to the maximum allowable pollutant carrying capacity in water body on the basis of meeting the water environmental quality standard of water function area.The calculation of pollutant carrying capacity is of great practical significance to the rational development & utilization and effective protection of water resources.Water conservancy projects such as sluice gates in rivers and lakes will change the hydrological process of rivers and lakes, thus affecting the pollutant carrying capacity of rivers and lakes.Taking the Tongshun River, a typical sluice-controlled river seriously disturbed by human beings, as the research object, this paper analyzes the pollutant carrying capacity of the main stream of Tongshun River under three conditions, namely 10 m~3/s, 13 m~3/s and 15 m~3/s, of the intake flow of Zekou sluice by the model method and pollution load method.The results show that different diversion scales have different effects on the pollutant carrying capacity of sluice-controlled river, and there is no complete positive correlation under the restriction of multiple parameters.With the continuous progress of water pollution control projects, the larger the scale of river diversion, the smaller the amount of pollutants need to be reduced.The calculation scheme presented in this paper can provide the basis for the establishment of scientific and feasible sluice dam regulation rules in Tongshun River, and also offer countermeasures and measures for river regulation.更多还原
