"4380 sewage treatment facilities inspections, more than 6,500 million tons of sewage turning water", this is the latest operating data from the development of Tianjin Zhangguizhuang sewage treatment plant.

The water plant is the first municipal sewage plant in China Railway Construction, and it is also the largest sewage plant project in the field of domestic sewage management in the field of domestic sewage in recent years. Since the transfer of the first phase of July 2021, the development of the "Multi -level AO Biochemical Reacting Pond+High -efficiency Sembrontation Tank+Nitrome Deep Bed Filter" has been introduced innovatively to ensure that the water quality indicators are stable to meet the standards. In addition, the project also uses harmless disposal technology to use 300 tons of sludge produced by sewage daily as garden green biofex. After improvement and energy consumption optimization, the energy consumption in 2021 decreased by 11%year -on -year.

According to reports, the sewage treatment plant can turn about 200,000 tons of sewage every day into purification water that meets national emission standards. The production of water for the water plant has all used its own purification treatment recovery water.

At present, the Tianjin Zhangguizhuang Sewage Treatment Plant has been operating the first anniversary of the safe and stable operation. The ranking of 9 in the Tianjin sewage industry inspection and evaluation has been increased by 9. The operating performance assessment has been well received by the competent authority of the Tianjin industry.

The second phase of the water plant will start construction in the second half of 2022, and use the smart water system for management. Through the digital management model, the production operation data can be monitored in real time. The vision of unattendedness has become the "new answer sheet" for China Railway Construction to build smart water.
