摘要: 以邻苯二甲酸二丁酯(DBP)为典型污染物,采用室内水槽试验、数值模拟及野外示踪试验,分析了水体中污染物降解的主要影响因素,研究了流速、含沙量、粒径等因素对污染物降解过程的影响,并将结果与水质模型进行耦合,提出了新的纳污能力计算方法。分别采用该方法以及《水域纳污能力计算规程》和《全国水资源综合规划地表水资源保护补充技术细则》的计算方法,计算了长江武汉段青山工业用水区DBP纳污能力。结果表明,基于数值模拟的纳污能力计算方法可以解决降解系数取值问题,可为更准确地核定水域纳污能力提供技术支撑。

Abstract: With dibutyl phthalate(DBP) as a typical pollutant, a novel method of calculating the allowable permitted assimilative capacity is put forward. The effects of flow velocity, sediment concentration, and particle size on the degradation of contaminants in water were analysed through indoor flume experiment, numerical simulation experiment and tracer experiment in river. And the analysis results were coupled with water quality model to establish this new method. The allowable permitted assimilative capacity of DBP in Qingshan industrial water functional zone was calculated respectively by this simulation-based method and the given methods from Standard Practice for Calculating Pollutant Carrying Capacity of Water and Supplementary Technical Rules for Surface Water Resources Protection of the National Integrated Water Resources Plan. Calculation results prove that this method solves the problem of the values of degradation parameters, and offers a technological support for confirming the allowable permitted assimilative capacity of river more accurately.

Key words: allowable permitted assimilative capacity of river, DBP, degradation coefficient, numerical simulation, tracer test
