Through experiment studied that the variation of air-water ratio, hydraulic loading, organic concentration in the removal of COD and NH 3 -N effects, observe and analyse the change of COD and NH 3 -N removal and the characteristics of microorganisms of filter’s different height. The results showed that COD and NH 3 -N removal are high under the condition of air-water ratio 4:1~5:1, hydraulic loading 1~2 m 3 / (m 2 ●h), organic concentration 300~400 mg/L. The concentration of COD and NH 3 -N of effluent which are treated by biological aerated filter can meet with second degree discharging standards.Read More
