8. RESEARCH ON APPLYING MIKE 11 MODEL TO EVALUATE THE QUALITY OF WATER RECEIVING SOURCE FROM VINH YEN DOMESTIC WASTEWATER TREATMENT PLANT

Tóm tắt

This study aims to assess the impact of wastewater discharge from the Vinh Yen 2 wastewater treatment plant on the water quality of the Phan River using the MIKE 11 model. The model simulated the spatial and temporal variations of key pollutants, including BOD₅, ammonium (NH₄⁺), total nitrogen (TN), and total phosphorus (TP), under two scenarios: with and without the operation of the Vinh Yen 2 plant. The results indicate that the operation of the plant significantly reduces pollutant concentrations in the downstream section of the Phan River, particularly for TN and TP, which remain below the limits of column B in QCVN 08:2023/BTNMT. These findings demonstrate the positive role of the new treatment system in improving regional water quality and support the sustainable management of wastewater in Vinh Phuc province.
