摘要
根据成都市西部南河的水文、水质资料和沿岸排污情况,以水质敏感点(某企业取水口)为节点,对河流进行计算单元划分,采用河流二维水质模型,计算对比不同典型年(偏丰年、平水年、偏枯年)水文条件下南河的COD和NH3-N的环境容量,并对计算结果进行分析,从而计算得到不同典型年各计算单元的污染物入河削减量,尤其是提出偏枯年条件下针对南河实际的排污总量控制建议,以达到南河的水质目标要求。
According to the hydrology, water quality and coastal sewage situation of Nanhe River in the southwest of Chengdu City, the river could be divided into some units, then the two - dimensional water quality model was used to calculate and compare the environmental capacity of COD and NH3 - N in different typical years （wet year,average year,dry year） .On the basis of the calculation results,the authors analyzed and calculated the amount of pollutants emissions to Nanhe River in different typical years, put forward some practical suggestions to control the total amount of pollutant emissions to Nanhe River in dry year, on the purpose of reaching the water quality objectives of Nanhe River.
