【 摘 要 】

Calculating the allowable permitted assimilative capacity under influence of hydropower development is meaningful for water pollution prevention. This paper takes Nan River as the research object, and uses river one-dimensional model, lake uniform mixing model and Dillon model to calculate the allowable permitted assimilative capacity of chemical oxygen demand and total phosphorus and ammonia nitrogen in Nan River. The results show that allowable permitted assimilative capacity of chemical oxygen demand and total phosphorus and ammonia nitrogen are 6901.93, 511.78 and 150.31 t/a, respectively in Nan River. This paper can provide guidance for the determination of APAC of river under the influence of hydropower development.
