Since its establishment, Guizhou Shuanglong Airport Economic Zone has always adhered to green development principles to achieve high-quality development. The zone is a national airport economic demonstration zone.
On Dec 31, 2020, the public-private partnership (PPP) water environment treatment project in the zone was completed, marking a new level of water pollution prevention and control work.
Early in 2015, the economic zone invested 4.26 billion yuan ($659.72 million) in sewage treatment plant construction, sewage interception pipe network construction, river dredging and river landscape improvement.
After years of construction, the economic zone has formed a 15-kilometer-long river ecological landscape belt along the Xiaobi, Maodong and Yuliang rivers.
The Longdongbao Sewage Treatment Plant with a daily processing capacity of 50,000 metric tons and the Dapo Sewage Treatment Plant with a daily processing capacity of 5,000 tons have also been built.
In terms of controlling air pollution, the economic zone has actively carried out essential tasks such as investigating and remediating heavy-polluting enterprises and volatile organic pollutants.
The atmospheric environmental quality compliance rate has remained above 96 percent for many years.
Shuanglong economic zone has also promoted the greening of barren hills, improved forest management and the management of mountains, and successively built 20 city and county-level demonstration parks such as Shuanglong Ecological Park.
