Based on the water environmental quality analysis of Songhuajiang Rivers in Jilin Province,the water management model is developed,which meets the standards of water environmental functions in different river sections,by integrating point sources with nonpoint sources,introducing response coefficient and optimal theory.
通过分析松花江吉林省段水环境质量现状,将点源与非点源污染负荷相结合,并引入响应系数和最优化理论,以各断面达到其水域功能水质标准为目标,建立水环境优化管理模型,并提出3个优化管理方案:(1)点源污水达标排放,城镇污水处理厂污染物按一级标准排放;(2)对非点源浓度进行控制;(3)在总排放量不变的情况下,实行点源排放量优化分配。
