Abstract

The operation condition of wastewater treatment plants has great influence on river water quality. Different simulated working conditions of overflow and water supplement in Guanlan River Basin were established in this study according to the sewage treatment capacity of decentralized sewage treatment facilities in the basin and water purification capacity of water purification engineering for Guanlan estuary storage pond. A hydrodynamic and environment mathematical model for Guanlan River mainstream was developed, using pollution indicators like COD, NH3-N and TP concentrations to quantitatively analyze the water quantity and quality of the basin under different working conditions overflow and water supplement and to simulate the water quality changes in the main under the different operating conditions. The calculation results show that: (1) If there were only one overflow point and the overflow volume does not exceed 30,000 m3/d, the water quality of Qiping Section can meet the assessment requirements; (2) If overflow occurs at both overflow points, the water quality of Qiping Section meets the assessment requirements only when the overflow volume downstream the Guanlan plant does not exceed 20,000 m3/d and the overflow volume upstream the terminal gate does not exceed 15,000 m3/d; (3) The concentrations of COD, NH3-N and TP along the main stream are obviously lower under all working conditions of water supplement. This research is expected to provide scientific basis for water pollution control of Guanlan River Basin.
