【 摘 要 】

In this paper, according to the river conditions and combined with the fully mixed model and the one-dimensional attenuation model, the concentration of pollutants at different distances is simulated, and the one-dimensional model is used to determine the sewage discharge capacity of the sewage treatment plant into the river drain. The result shows that under the current working conditions and design conditions, the status of pollution in the downstream affected zone of the river inlet is more than the capacity of the zone. In addition, the simulation result shows that COD and Ammonia nitrogen concentration gradually decrease due to the gradual degradation of pollutants in the longitudinal migration. Therefore, the sewage discharge port of the sewage treatment plant is set under the current working conditions and the design conditions, and the total amount of COD and Ammonia nitrogen missions does not exceed its pollution holding capacity. The section of the river still has a certain potential for pollution, and the water quality of the water can meet the water quality target requirements of the corresponding water function zone, and will not affect the function of Dongzhulong River.
