- Abstract:
- River water quality to meet surface water standard is an important assessment content in black and odorous water treatment projects. The establishment of scientific and appropriate boundary conditions for water quality to meet the surface water standard is the key to the smooth promotion of the project and passing the assessment. Influence of precipitation, interception and upstream inflow on water quality of a river improvement project in an urban area in Southwestern China was analyzed by using hydrodynamic coupled mathematical model and orthogonal analysis method,and the optimal factor combinations for river water quality to meet the surface water standard after precipitation was obtained. Reasonable boundary conditions and project scale for river water quality to meet the surface water standard were determined through checking and analyzing. The application of orthogonal analysis method has the advantages of simplicity, comprehensive analysis and accurate results.
