Calculation for Water Environmental Capacity of Total Phosphorus in Urban-type River PanLongJiang

For total amount of water pollutant control,river PanLongJiang water environmental capacity was divided into four sections.Total Phosphorus integrated degradation coefficient of river PanLongJiang was determined by two-point tracer monitoring method,and verified using one-dimensional water quality model.Water environmental capacity of TP of each section was calculated by one-dimensional water environmental capacity model.The results showed that TP integrated degradation coefficient of river PanLongJiang was 0.016 d-1±0.002 d-1,and that the capacity for TP in the sectionⅠ,sectionⅡ,section Ⅲ and section Ⅳ of river PanLongJiang were respectively 1.60 t/a～1.61 t/a,10.00 t/a～10.02 t/a,14.52 t/a～14.60 t/a,and 22.23 t/a～22.28 t/a.It would help the prevention and treatment of water pollution for the Dian Lake.
