摘要
利用流域水环境系统模型,以水功能区水质目标为依据,计算出长系列设计水文条件下的各控制单元的动T态MTDMLD基L。础基上于,水对生污态染承物载进力行权优重化,分综配合,考得虑到社各会控、制经单济元、的环污境染等物因允素许构排建放了量多和目削标减优比化例模,型从,而在形各成控了制基单于元流域的的总量分配技术体系。并将该方法应用于太湖流域典型区域污染物总量研究,实现了其污染物总量分配。
On the basis of the water quality targets of water function zone,a watershed water environmental model is used to calculate the dynamic TMDL of the control units within Tahui Lake Basin with a long time series of hydrological condition.Based on the water ecological carrying capacity theory,a multi-objective optimization model is developed considering social factor,economic factor,ecological factor and environmental factors.The multi-objective optimization model is used for optimizing distribution of the pollution loads among different pollution sources based on the TMDL of each control unit.Thus,the watershed pollutant allocation method system is composed of the watershed environment model,the dynamic TMDL calculation model,and multi-objective optimization model.The proposed method was used for the total pollutant allocation in the Taihu Lake Basin and the allowable pollutant emissions and pollutant reductions of each control unit are finally obtained.
