●  Project Overview:

This project adopts the treatment process of "AOA biochemical pond+secondary sedimentation pond+cloth filtration pond" which is the core of "sludge double reflux AOA advanced nitrogen and phosphorus removal process", applied for the first time in construction projects nationwide, and is also a characteristic project which we cooperate with an academician of Beijing Institute of Technology.  According to the inspection requirements of the Central Environmental Protection Inspection Group, this project has a tight schedule and featured as heavy tasks, innovative processes, and complex technology. Meanwhile, the original plot of land in the factory area was filled with garbage, with poor geology and a large difference in backfill height. The design adjusted the layout of the process flow, resulting in effective risk control, technological innovation, and stable operation of the plant.
