Abstract
In this paper, we analyzed the current situation of water pollution sources near Macao airport, established a two-dimensional water exchange and water quality mathematical model near the project, and compared and simulated the reclamation schemes of Macao airport. According to the results of water exchange and COD calculation of water quality, the 80 m channel scheme was remarkably better than the 40 m one in terms of water exchange capacity and the possibility of achieving the water quality target. However, with the increase of channel width, the variation of water exchange rate and half exchange period would slow down. There was no significant difference in water exchange rate, water exchange period and water quality distribution between 80m channel and 120 m channel. The final scheme was to adopt the 80 m channel.
Highlights
The building of Macau International Airport was officially started in 1989 and completed in 1995. It is composed of runway artificial island, parking apron, terminal building and two taxiing bridges connecting artificial island and the apron
The water quality near Macao airport is affected by the upstream and downstream water and the tail water discharged from the nearby sewage treatment plant, and affected by the domestic sewage, factory waste water and initial rainwater discharge in surrounding land
The domestic sewage from Jiuao village and the Container terminal is directly discharged into the sea, and the sewage from workers in Luhuan power plant is discharged after being treated by the sewage treatment equipment of the power plant
Summary
The building of Macau International Airport was officially started in 1989 and completed in 1995. It is composed of runway artificial island, parking apron, terminal building and two taxiing bridges connecting artificial island and the apron. Some facilities have been saturated, such as commercial aviation facilities, passenger terminal buildings and land transport facilities, while other facilities, like the parking apron, will be inadequate one after another. The reclamation in the triangle area on the west of the airport runway artificial island will change the current connection between the upstream and downstream, and may have adverse effects on the ecological environment of the surrounding waters and the drainage of the land area on the west side of the airport. On the basis of full consideration of the land conditions and expansion needs of the waters around the airport, the comparison and selection of airport expansion schemes are carried out from the perspective of protecting the water ecological environment
