Calculation of assimilative capacity in Huangshui River based on one-dimensional water quality model
According to the monitoring data of each hydrologic station in Huangshui,the average flow rate of 90％ reliability of many years,COD and NH3-N as the control factors of main pollutants in the river.The one-dimensional water quality model are used to quantitative calculation the water assimilative capacity of the Huangshui River in the water functional area,COD and NH3-H assimilative capacity are 13 250.0 t/a and 543.3 t/a.Through the calculation and analysis,the theoretical results of chemical oxygen demand and ammonia nitrogen pollutant capacity in each water functional area can be obtained for the implementation of the most stringent water resources management system assessment,the further implementation of the various stages of pollutant discharge limit indicators to ensure that water resources sustainable use,support the sustainable development of the national economy to provide theoretical basis for decision making.
