【摘要】 针对上游来水量小的缺水河流,沿岸污染源排放对河道水文条件影响显著的特点,考虑旁侧入流对环境容量的影响,建立了缺水河流水环境容量计算模式,以及面源污染物削减分析方法。以台肥市南淝河为例,计算出现状城区河段点源全收集条件下的面源环境容量;并基于排水系统溢流水质监测和河道水质监测数据反向校核,估算出城区排水系统雨天溢流污染负荷。建议台肥城区排水系统面源污染负荷削减52%,使南淝河城区段达到V类水环境功能目标。更多还原

【Abstract】 For the low upstream inflow river,influence of side inflow on river hydrologic pattern is significant.In this study,a water environmental model was established with side inflow effect incorporated,and hereby non-point abatement approach was presented.Taking Nanfei River in Hefei City for example,the allowable non-point pollutants discharging into urban river watr courses,that is,the allowable urban drainage overflow,was presented combining the reverse calibration based on river water quality data,for the scenario of interception of all point pollution sources discharging into river courses.It is suggested that non-point pollutants discharging into urban water courses should be lowered by 52%,so as to attain water use objective of grade V.更多还原
