If you visit Nanchang and Jiujiang cities in east China's Jiangxi province, you will marvel at their lush green, picturesque mountains and clear waters. The feat they have achieved in ecological protection is the source of Jiangxi's confidence and strength for development.
The province is implementing targeted measures to promote green development and maintain its blue sky, clean water and eco-friendly land, balancing economic development with environmental protection.
From dump site to power plant
In the Nanchang Economic and Technological Development Zone, a garbage storage area whose foul odor used to plague the people living nearby, has been transformed into a power generation site.
The Jiangxi Hongcheng Environment Co. has built two biogas power plants under the garbage storage area. Every day, three large cranes pick up the trash in their giant claws and feed it to a nearby furnace.
"The heat energy produced from burning the garbage is converted into clean electricity and supplied to the national grid for consumption needs nationwide," said Xiong Wei, vice general manager of the Hongcheng Environment. This has not only cleaned up the area, but also boosted the circular economy.
Innovative sewage treatment
The Xinjian Ecological Water Plant in Nanchang has hidden its sewage treatment plant underground. Overground, a green park has been built for leisure activities.
"We adopted the concept of 'pollution treatment underground, park overground' in building the plant," said Zeng Kai, executive vice general manager at the Jiangxi JDL Environmental Protection Co., which operates the wastewater treatment plant.
Currently, the plant treats about 20,000 tons of wastewater daily. Some of the treated water is discharged to form a water landscape in the ecological park, where people like to go for an outing. The remaining treated water meeting the discharge standards is released into the rivers or land to promote water recycling.
China Petroleum & Chemical Corporation (Sinopec)'s Jiujiang branch has also joined the ranks of eco-friendly pioneers.
Sinopec has implemented environmental control measures, achieving 100 percent compliance with the regulations for wastewater discharge, controlled emissions, and proper disposal of hazardous waste. "Treating wastewater is as crucial as producing premium oil. It is very important to do the source control for the environment," said Yu Dingping, who is in charge of the inspection and measurement at the Jiujiang branch.
"A new equipment is used to extract organic waste from wastewater and send it directly to the hydrogenation furnace, producing hydrogen gas and saving over 300 tons of coal annually," said Tang Anzhong, an environmental protection management expert at the Jiujiang branch.
Jiujiang has built 21 urban sewage treatment plants with a daily treatment capacity of 667,500 tons. In the first quarter of this year, the proportion of the best water environment quality in Jiujiang in the national surface water assessment section reached 100 percent, as per official statistics.
