It is understood that this project is one of the first batch of PPP (government and social capital cooperation) demonstration projects in Anhui Province. The design scale of the project is 200,000 square meters/day, and the maximum processing capacity is 260,000 square meters/day. It is estimated that the project will be fully completed in June next year. After completion, the service scope can reach 66 square kilometers, which will effectively alleviate the sewage treatment pressure in Hefei.
"Compared with the sewage treatment plant, Qingxi Water Purification Plant saves 2/3 of the land." Zhang Yuanming, the project manager, said that compared with the traditional sewage treatment plant, the totally buried Qingxi Water Purification Plant has unique advantages in terms of floor space, use efficiency and urban landscape improvement.

Although the floor space has been reduced, the sewage purification capacity of Qingxi Water Purification Plant has not been "discounted". Zhao Eryan, deputy general manager of the operator, said: "The water quality after many processes, such as coarse and fine grid filtration, lifting, primary precipitation, biochemical reaction, secondary precipitation and biofilter, has exceeded the first-class A standard of the national standard." He said that the water treated by the factory will eventually flow into the Fei River, which will greatly improve the water quality of the river.
