【 摘 要 】

Due to the development of economics and society in China, the huge amount of wastewater becomes a serious problem in most of the Chinese cities. Therefore, the construction of wastewater treatment plant draws much more attentions than before. The discharge from the wastewater treatment plant is then considered as a point source in most of the important rivers and channels in China. In this study, a typical wastewater treatment plant extension project is introduced as a case study, a filed monitoring experiment is designed and executed to observe required data, then, a two-dimensional model is estabilished to simulate the water quality downsteam of the wastewater treatment plant, CODCris considered as a typical pollutant during the simulation. The simulation results indicate that different discharge conditions will lead to different CODCrconcentration downstream of the wastewater treatment plant, and an emergency plan should be prepared to minimize the risk of the pollution in the channel under unusual and accident conditions.
