摘要
本文根据禅城区汾江河的水动力参数和水环境条件,建立了一维感潮河网水流水质数学模型,利用数学模型来计算禅城区内河涌的水环境容量。模拟计算表明:按水环境容量折算成的汾江河COD允许排放量为2498.1t/a,氨氮允许排放量为139.0t/a,总磷的允许排放量为24.0t/a。而汾江河主要河涌2012年COD实际受纳量为5442.7t/a、氨氮实际受纳量为704.5t/a、总磷实际受纳量为71.4t/a。这充分说明,汾江河污染受纳量大大超出允许排放量,需要进行排污总量削减。
According to the hydrodynamic and water environmental conditions of Fenjiang River, this paper adopted a one - dimensional tidal river network mathematical model to calculate the water environmental capacity of Fenjiang River. The simulation calculation shows that： by converting the water environmental capacity of Fenjiang River, the allowed emission for COD is 2498. lt/a, the allowed emission for ammonia nitrogen is 139.0t/a, the allowed emission for total phosphorus is 24.0t/a. While the actual emissions to main stream of Fen River in 2012 were： 5442.7t/a of the COD, 704.5t/a of the ammonia nitrogen and 71.4t/a of the total phosphorus . It shows that the actual pollution emissions to Fenjiang River greatly exceeds the permitted emissions, and the total amount of emissions need reducing.
