Upgrade and Operation of Nitrogen and Phosphorus Removal Process in the Sewage Treatment Plant of Jinan City

Abstract:

The designed capacity of Jinan Citys wastewater treatment plant (the second sewage treatment plant) is 200,000 m³/d, and the biological treatment process is DE-type oxidation ditch process. Because of self-control requirements, equipment quality and management , alternat-ing operation of anoxia and oxygen can not be achieved. Acting in concert with the engineering of south-to-north water diversion and water quality improvement of the Xiaoqing River, water quality improvement and transformation of nitrogen and phosphorus removal process was condu-cted. By increasing the diversion wall, digestive reflux and other measures, the DE oxidat-ion ditch process was transformed into A²/O process, while the depth of V-efficiency fiber filter processing and chemical phosphorus removal process were increased. After the upgrade, the process is stable, the effluent quality reached an A standard of " discharge standard of pollutants for municipal wastewater treatment plant" (GB18918-2002).
