摘要
针对黄河龙门-三门峡区间水质变化复杂的特点,用多个设计流量、多个控制指标、多个纳污模型对其区间纳污能力进行计算,用90%、75%、50%不同设计保证率下的河道断面流量计算COD和NH3-N的纳污能力,且不同设计流量采用不同的降解系数,从而计算出多组纳污能力值。对于多组纳污能力,提出采用纳污能力最小值和最大值区间作为纳污能力计算结果,为决策者留有决策空间。
It is difficult to calculate the water environmental capacity of the Longmen-Sanmenxia section of the Yellow River due to the complex variation of water quality. A new calculation method is proposed to calculate the water environmental capacity by applying multi-design discharge, a multi-model, and a muhi-index. The water environmental capacities of COD and NH3-N were calculated using the discharge at design reliabilities of 90% , 75% , and 50%. In order to calculate multiple groups of water environmental capacities, different degradation coefficients were used for corresponding design discharge. The minimum and maximum intervals of water environmental capacity are proposed, which can provide decision space for decision-makers.
