November 30, after more than two months of commissioning operations, Anhui's first fully buried sewage treatment plant project - Hefei Qingxi water purification plant successfully passed the environmental acceptance, into the water operation stage.
It is understood that the project is one of the first PPP (government and social capital cooperation) demonstration projects in Anhui Province. The project design scale is 200,000 cubic meters / day, the maximum treatment capacity of 260,000 cubic meters / day, is expected to be fully completed in June next year. After completion of the service area of up to 66 square kilometers, will effectively ease the pressure of sewage treatment in the Hefei area.
"Compared with the sewage treatment plant, the Qingxi water purification plant saves up to 2/3 of the land," said Zhang Yuanming, the project manager, adding that compared with the traditional sewage treatment plant, the all-embedded Qingxi water purification plant has unique advantages in terms of footprint, service efficiency, and improvement of the cityscape.

While the footprint is "reduced", the sewage purification capacity of the plant has not been "discounted". The operator's deputy general manager Zhao Eryan introduced: "After coarse and fine grating filtration, lifting, primary sedimentation, biochemical reaction, secondary sedimentation, biofilter and other multi-channel process treatment of water, water quality level has exceeded the highest level of the national standard of the first class A standard." He said the plant's treated water eventually flows into the Inter River, which will greatly improve the river's water quality.
