Abstract :
The raw water was diluted in four levels of 20%, 40%, 60%, 80% in the bio-membrane initiating process. When the raw water concentration was invariable , and hydraulic retention time, dissolved oxygen, pH and water temperature were 3 h, 3.5 mg/L, 7.05 ~ 8.23, 17.4 ~ 30.6°C respectively. Results showed removal rates of combined packing to COD, BOD5, NH3-N and TP were about 76.3%, 78.4%, 74.9% and 58.8%.
