The Guizhou Shuanglong Airport Economic Zone, located in Guiyang city, capital of China's Southwest Guizhou province, is reportedly continuing to achieve success in pushing ahead with its green development.
It's a continuation of the template set at its establishment in October 2014, when the zone firmly adopted environmental and ecological priorities and took the path to green development, identifying it as its biggest development advantage and competitive advantage.
In terms of sewage treatment, in 2015 the zone invested 4.26 billion yuan ($649.1 million) to implement a series of comprehensive water environment management projects including sewage treatment facilities, installation of a sewage interception pipeline network, river dredging and river landscape improvements.
Moreover, it has built a 15-kilometer river landscape green belt along the Xiaobi, Maodong and Yuliang rivers -- and established the Longdongbao sewage treatment plant with a processing capacity of 50,000 metric tons per day, as well as the Dapo sewage treatment plant with a processing capacity of 5,000 tons per day.
The zone has also carried out key tasks such as investigations into and remedial work at small, poorly managed and heavily polluting enterprises, as well as restricted the use of high-polluting fuels.
As a result, the air quality compliance rate in the zone has been maintained at more than 96 percent for many years.
In February 2021, Shuanglong reportedly ranked first among all the districts, cities, counties and development zones in the city in terms of air quality.
Meanwhile, the zone completed 13,000 mu (867 hectares) of afforestation and established 20 city and county-level parks.
The zone also introduced third-party environmental management agencies in 2017. That was in order to facilitate environmental management work, such as river inspections and corporate environmental protection training, as well as to guide businesses on how to improve their pollution prevention and control measures.
