摘　　要：文章建立了张家港市水环境数学模型,并同步进行了野外水量水质监测,通过模型率定得出水质综合降解系数,采用90%保证率典型年(1971年)最枯月平均流量作为设计水文条件,通过水环境功能区总体达标法计算得出张家港市现状水环境容量,其中COD为43742.9t/a,氨氮为3527.6t/a。This paper takes Zhangjiagang City as research object,a quantity and quality model is established and calibrated by synchronous monitoring data.Based on this,the comprehensive degradation coefficient of water quality is obtained.Then,90%guarantee rate most dry month average flow is selected as the design hydrological condition.To ensure the overall water quality,we calculate that the water environmental aapacity of COD and NH;-N are 16647.3 t/a and 1021.5 t/a respectively.
