摘 要:
Guangzhou Liede Sewage Treatment Plant phase Ⅱ,which adopted the UNITANK process,has been used for 9 years.The design scale is 220 000 tons per day.The removal efficiencies for organic maters,nitrogen and phosphorus pollutants were high,and the effluent concentration could reach the first class A standard of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB18918-2002).The MLSS concentration in biochemical pool was about 3 000 mg/L,and the sludge loading rate was about 0.14 kgBOD5/(kg MLSS·d).Compared with the design parameters,the practical operation was very close to the design requirement.
