- Abstract:
- The construction scale of the first phase of Fenghuangqiao wastewater purification plant in Lu’an is 4×104 m3/d, and the second phase of the project will increase the construction scale to 9×104 m3/d. The effluent quality should comply with the combined requirements of the class A standard of the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002) and the Discharge Limits of Major Water Pollutants for Municipal Wastewater Treatment Plants & Industries in the Chaohu Basin (DB 34/2710-2016). By exploring the potential of the first phase project and making partial transformations, the treatment capacity was enhanced to 5×104 m3/d while ensuring that the effluent met the new standard. Improved Bardenpho biological tanks and horizontal flow sedimentation tanks were adopted in the second phase project, and deep-bed filters/sulfur autotrophic denitrification filters were adopted to remove nitrogen, while advanced oxidation was adopted to remove emerging contaminants. The treatment capacity could be increased to 13×104 m3/d during the rainy season through the adjustment of operation. The operation results indicated that the effluent quality could meet the standards steadily.
