Review and Summary of Key Technology for System Commissioning of Taihe Full Underground Wastewater Treatment Plant

Taihe Wastewater Treatment Plant is the largest wastewater treatment plant (WWTP) with the whole process and full underground intensive layout in China. The construction scale of the first phase project is 400 000 m3/d. The scheme optimizing the sludge inoculation cultivation and acclimation, the linkage scheduling of system pipe network, the optimization of commissioning sequence and the others are adopted in the commissioning process. Within the shortest time, the up-to-standard discharge of WWTP has been realized and the environmental efficiency of Taihe Wastewater Treatment Plant has been brought into play. The key technologies in the commissioning process of Taihe Wastewater Treatment Plant are reviewed, and the commissioning points of the full underground large-volume WWTP are summarized.
