Experimental Study on Domestic Sewage Treatment by Biological Aerated Filter

摘要：

On the up-flow biological aerated filter to remove COD and NH3-N were studied the effect and contrast in various stages of finding the optimal operating conditions, so as to achieve energy conservation, the purpose of reducing operating costs. Through experiment studied that the variation of air-water ratio, hydraulic loading, organic concentration in the removal of COD and NH3-N effects, observe and analyse the change of COD and NH3-N removal and the characteristics of microorganisms of filters different height. The results showed that COD and NH3-N removal are high under the condition of air-water ratio 4:1～5:1, hydraulic loading 1～2 m3/(m2·h), organic concentration 300～400 mg/L. The concentration of COD and NH3-N of effluent which are treated by biological aerated filter can meet with second degree discharging standards.
