The Government Work Report, delivered at the annual national legislative session in Beijing last March, has called for the expansion of effective investments, with a focus on national development strategies and the needs of the people, particularly in major infrastructure and public well-being projects.

"This project is a living example of the idea that 'lucid waters and lush mountains are invaluable assets', as it not only solves the problem of sewage treatment, but also creates a beautiful ecological environment, greatly improving the well-being of the local people," said Jiang.

He noted that an existing sewage treatment plant nearby had issues with inadequate deodorization technology, often resulting in unpleasant odors that caused suffering to local residents.

Li Jianmin, a resident near Fenghe River, said: "I could always smell the pungent odor when passing by the old factory. I hope the new park is completed sooner."

Jiang assured that the 'invisible' plant would completely change the situation, through the adoption of a 'plasma + biological filtration + activated carbon adsorption' deodorization process, leaving no odor at all.

"Moreover, we established an intelligent ventilation and monitoring system to control air quality through zoning linkage, truly realizing the 'underground digestion' of pollutants," he added.

With the topping-out of the main structures, the sewage treatment plant's operation is drawing closer, marking a significant step toward the completion of the smart eco-park.
